Cleaning & Care

How to clean the burner bases.

Make sure the cooktop has cooled completely before cleaning the burner bases. Clean the burner bases with hot water, mild detergent, and a soft cloth. Use a stiff nylon toothbrush to clean port openings. Do not scratch or gouge the port openings. Rinse and dry. Dry the burner cap thoroughly after cleaning.

How to clean the burner caps.

Make sure the cooktop has cooled completely before cleaning the burner caps. Clean the burner caps with hot water, mild detergent, and a soft cloth or sponge. Rinse and dry. Dry the burner cap thoroughly after cleaning. Do not soak burner caps.

How to clean the control knobs.

To remove knobs, simply pull them straight forward. Use hot, sudsy water with a soft cloth. Rinse and dry. Do not soak the knobs or use abrasive cleaners and scrubbers.

How to clean the igniters.

After the igniters have cooled down, carefully wipe them with a cotton swab dampened with water. Gently scrape off any soil or debris with a toothpick. Avoid exposing the igniters to excessive water, as a damp igniter may not light up.

How to clean and season the griddle.

Wash with warm, soapy water. Rinse thoroughly and dry with a soft cloth. To season, spread a small amount of vegetable oil evenly while heating (avoiding corners). When the oil begins to smoke, turn it off. Repeat this process two more times and re-season as needed. Seasoning will help protect the griddle from rusting and prevents foods from sticking to the surface during cooking.

How to clean the grill.

Burn the grease off the briquettes using the HI setting. While the grill grate is still hot, use a wire brush dipped in hot water to remove the soil from the grate.

How to activate the oven's self-cleaning feature.

All models have slightly different instructions. Please refer to your owner's manual to learn how to self-clean your oven. View the Thermador YouTube Channel to learn how to prep your oven for self-cleaning .

Oven is not self-cleaning properly

Before running the self-clean feature, allow the oven to cool, wipe away loose soils/debris or heavy spills, and remove the racks and all other accessories from the oven. Set the oven to the maximum self-clean time if the oven is badly soiled.

Can I use oven cleaner in my self-cleaning oven? 

No, we do not recommend using chemical cleaners in self-cleaning ovens. The porcelain surface is smooth and chemical cleaners may cause surface damage.

How to clean the spots that remain inside the oven window after a self-clean mode.

Use hot, soapy water on a non-abrasive sponge. Squeeze most of the water out before wiping. Rinse the glass and dry.

My oven does not self-clean. How do I clean my oven?

Use hot, soapy water or a mild cleaner and a nonabrasive sponge. Only use mild cleaners such as Soft Scrub, Bon-Ami or Ajax . Rub lightly with a nonabrasive sponge, rinse thoroughly and dry with a soft cloth. If food has burned onto the oven and is difficult to remove, use a mild cleaner with an SOS or Brillo pad and rub gently. The Ajax, SOS pad, and the Brillo pad may scratch the porcelain in the oven interior. This does not affect oven performance.

How to remove light soil from the oven.

Use hot, soapy water on a paper towel. Rinse thoroughly and dry with a soft cloth.

How to clean the oven racks.

Wash with hot, soapy water, and a soft cloth. Rinse and dry.

Do not clean the racks in the self-cleaning oven. If flat racks are cleaned in the oven during the self-cleaning mode, they will lose their shiny finish and may not glide smoothly. If this happens, wipe the rack edges with a small amount of vegetable oil and then wipe off.

How to clean the telescopic rack.

Wash with hot, soapy water, and a soft cloth. Rinse and dry. Avoid getting cleansing powder or residue in the telescopic slides. Re-lubricate the telescopic slides as needed by using high-temperature food-grade lubricants.

How to clean fiberglass gasket.

Do not clean the fiberglass gasket.

I ordered the wood block accessory cover for the griddle. How do I protect it from absorbing stains?

Protect the wood from harboring soil and bacteria by applying unscented mineral oil to the surface. Use small amounts of oil and repeat until the surface does not allow soil to penetrate. Do not use any other types of oil for this function as it will turn rancid over time. Reapply after scrubbing with detergent and hot water.

How to clean stainless steel surfaces.

Clean stainless steel areas by using mild, soapy water with a soft cloth. Wipe in the direction of the stainless steel grain when washing and drying. Rinse with water and wipe dry to avoid watermarks. Do not use cleaning agents that are abrasive or contain chlorine since both are corrosive to stainless steel. For added shine, apply stainless steel conditioner and wipe off excess with a soft cloth.

Warning: Stainless steel conditioners and cleaners can have negative effects on materials other than stainless steel. Do not apply stainless steel conditioners and cleaners to control labels, logos, or black stainless steel.

The Thermador Stainless Steel Conditioner (part # 00576697) is available for purchase in the online Thermador Accessories Store > . View the Thermador YouTube Channel to learn how to clean stainless steel .

How to clean the glass surface of the range.

Wash with hot, soapy water, and a soft cloth. Rinse and dry. A glass cleaner can also be used to clean the glass.

How to clean the porcelain surface of my range.

Immediately wipe away acid spills like fruit juice, milk and tomatoes with a dry cloth. Do not use a moistened sponge or cloth on hot porcelain. When the oven has cooled, clean it with hot, soapy water and a soft cloth. Rinse and dry. It is normal for porcelain to show fine lines with age due to exposure to heat and food.

How to clean the painted surface of the range.

Wash with hot, soapy water and a soft cloth. Rinse and dry. Do not use powdered cleaning agents, steel wool pads, oven cleaners, and other abrasive cleaning materials.

Usage & Operation

The gas burner does not start.

Make sure the gas shut off valve is in the ON position and the gas supply is on. The burners must be positioned properly. Check to see if there are any food debris in the burner ports and clean as needed. The igniters also must be clean and dry for the burner to start. Check the power supply and make sure the unit is plugged in and the circuit breaker has not tripped.

It is hard to ignite the gas rings – burners are not igniting or there is a constant clicking sound.

There are several solutions to this problem:

  • The igniter ports may be dirty. Carefully wipe the igniter with a cotton swab dampened with water after the igniter has cooled down. Gently scrape soil off with a toothpick. Avoid exposing the igniters to excessive water as a damp igniter may not light up. Remove any lint that may remain after cleaning.
  • Ignition will be quicker if a cooking pan is in place on the grate. Ignite the gas at full and once alight, turn down to around 50%. It should lock on within 6 seconds.
  • The main gas supply may not be turned on. Make sure it is turned on.
  • Does the burner click when the burner knob is in the ON position? If yes, you may have a wiring issue at the outlet that the appliance is connected to. Turn off the main gas supply and contact a qualified electrician to fix this.
  • Does the burner click when the burner knob is in the OFF position? If yes, check for the following:
    • 1. Burner caps are properly placed and the igniter is not wet or dirty.
    • 2. Check to see if the regulator supplied with the unit is installed properly. The arrow on the regulator should be pointing to the appliance. Please call a professional installer or schedule a service visit if the regulator has not been installed properly.

The ignition spark operates continuously.

There are several solutions to this problem.

  • The knobs may be in the LIGHTING/SPARK position. Turn the knobs to the OFF position.
  • Make sure there is no draft in the room. Select models have a re-ignition function, which is part of the flame recognition feature. The re-ignition function will attempt to reignite a flame that has been blown out or disturbed.
  • This may be caused by the presence of water due to cleaning the cooking surface with excess water or water boiling over onto the cooking surface and entering the appliance. This problem will cure itself once the cooking surface dries out.
  • If you have tried all of the above and the problem continues, you will need an authorized service technician to dismantle the appliance and repair it. You should never attempt to dismantle a gas appliance unless you are officially qualified to do so. Please schedule a service visit .

For cooktops purchased after September 2018, the ignition spark operates continuously if a knob is held down past the child lock position.

The igniter makes more than four clicks before lighting.

Align the burner caps properly on the burner base.

The igniters spark even though knobs are in the OFF position.

There are several solutions to this problem:

  • When an electrical power connection has been activated at the first power up or reconnected after an outage, the igniters may spark once or twice even though all burner knobs are in the OFF position. If igniters continue to spark, schedule a service visit .
  • This may be caused by the presence of water from cleaning the cooking surface or water boiling over onto the cooking surface and entering the appliance. This problem will cure itself once the cooking surface dries out. If the problem persists after several days, schedule a service visit .
  • The igniter box may have failed and you will need to schedule a service visit .

There is intermittent sparking.

The ceramic igniters are wet or dirty. Carefully dry or clean the igniter. Intermittent sparking can also happen if the burner ports are clogged. Clean ports on burner cap with a wire, a needle, or straightened paper clip. Intermittent sparking can also be caused by air movements or gusts in the room. Make sure there is no draft in the room.

The burner flame goes out unexpectedly.

Make sure there is no draft in the room.

The flames are too high or are uneven.

There are several solutions to this problem.

  • The burner caps may not be installed properly or may have been moved. Make sure the burner caps are properly positioned.
  • The regulator supplied with the unit may not be installed. Please ask a professional installer to install it or schedule a service visit .

The gas burners have the automatic re-ignition feature. Occasionally, one burner will not light while all the others do light.

The burner cap is out of alignment. Adjust the cap so that the tab fits into the notch in the burner base.

There is a gas odor coming from the cooktop.

There are several solutions to this problem:

  • The burner knobs may not be completely turned off. Turn the knobs to the OFF position. If the smell does not go away after doing this, turn the main gas supply off and schedule a service visit .
  • Does the smell disappear when the burner is lit? It is normal to smell gas for up to four seconds after igniting the burner. The smell will go away after the burner is lit. If the smell does not go away when the burner is lit, turn the main gas supply off and schedule a service visit .

What is the Star™ Burner?

It is a 3-in-1 burner that is exclusive to Thermador and features high performance, 5-point design, and ExtraLow® burner capability. The Re-engineered Star™ Burner provides unsurpassed flame spread, faster time-to-boil, and rapid recovery time. Designed in a star shape, it provides more even heat to your cookware.

Why would I need ExtraLow®?

ExtraLow® will keep a consistent or low simmer, which will prevent your food from burning or scorching.

What are the BTU levels on Thermador rangers?

The BTU levels vary depending on the model. Thermador's Professional® Series of ranges and rangetops have a higher amount of BTUs than Thermador Masterpiece® Series gas cooktops.

Can I order a Natural Gas or LP Gas range?

Yes. All gas ranges are factory Natural Gas or Liquid Propane (LP). Dual-fuel ranges are factory Natural Gas.

The LP Conversion Kit can be purchased in the online Thermador Accessories Store > .

Can I put a downdraft ventilator behind a Professional® Series range?

No. We strongly recommend a Professional Series hood with all Professional ranges.

Do you need ventilation over a range?

Yes, all ranges, rangetops need ventilation.

Do I need to install the anti-tip bracket?

The anti-tip bracket is not needed for 48” Harmony units.

However, the anti-tip bracket is needed for all other Thermador units. You may be held legally responsible if the anti-tip bracket is not installed and for any damage or injury that occurs due to it not being installed.

Overtime, the grates become shiny.

This is caused by using inexpensive, non-coated, aluminum pans on the grates. The texture of the grates can remove bright, shiny aluminum from the pan because the pan is non-coated. The shiny aluminum fills in areas on the grates and makes the grates shiny. There is nothing wrong with the grate.

If you use non-coated, bright, non-colored, aluminum pans on the grates, try to gently clean off the shiny spots with a clean, new Scotch-Brite abrasive pad or a coarse, steel wool pad.

The food is cooked unevenly.

There are several solutions to this problem:

  • The base of the pan may be warped. Use a different pan.
  • Make sure to place the pan over the center of the burner so the heat is evenly distributed.

The oven light does not turn off.

Check for any obstructions in and around the oven door and check to see if the hinge is bent.

There is smoke coming out of the oven during the initial use.

Yes, ovens have factory oils and they will burn off. Rid oils faster by turning the oven on for 15 more minutes or by wiping the oven with hot, sudsy water before use.

What is convection?

An oven that has a fan, which constantly recirculates the heated air has "Convection" mode. This moving air strips away the natural thermal barriers that surround food and allows the heat to start cooking sooner. It will dry the food's outside surface, while the inside remains moist.

How can I get the best results from convection cooking?

Use low-sided, metal pans so that the heat can reach as much of the food's surface as possible.

Should I leave the oven door open while broiling?

No, this is not necessary. Make sure the oven is closed during broiling and this will reduce the amount of heat in the kitchen.

When is it necessary to preheat the oven? 

Preheat for delicate foods that have short baking times, such as cookies, cakes, and muffins. These types of foods need more precision timing for good results. Conversely, roasts and casseroles do not require as precise timing.

Baked goods are overdone or underdone.

This may be due to an error in the baking technique (human error) or the oven may not be performing optimally. Performing the Biscuit/Cookie Bake Test will let you know if the cause is human error or oven error. We use this test to help develop our ovens:

1. Purchase Pillsbury Grands Biscuits or Pillsbury Sugar Cookies. They are “unbaked” and can be found in the refrigerated section of most grocery stores.

2. Use a shiny, aluminum cookie sheet that is 12 x 15” or larger.

3. Follow package instructions for laying the biscuits/cookies out on the cookie sheet. Failure to follow package recommended spacing will negatively affect bake results.

4. Do not put the cookie sheets into the oven until PREHEAT is finished.

5. If baking one cookie sheet, place it on rack position 3. If baking two cookie sheets at once, place them on rack positions 2 and 4.

6. Follow package instructions for baking time.

7. Do not open the oven door once the biscuits/cookies have been put into the oven. Use the oven light and window to view the biscuits/cookies if you wish.

8. At the minimum baking time listed on the package, check the baking results through the window. If the biscuits/cookies are not baked to satisfaction, check them every minute and allow them to bake more until fully baked or until the maximum baking time listed on the package has been reached, whichever happens first.

9. If the biscuits/cookies turn out well during the baking times noted on the package – this means the oven is performing properly and does not need a service visit.

10. If the biscuits/cookies turn out overdone or underdone during the baking times noted on the package – this means the oven needs to be checked by an authorized Thermador servicer. Please schedule a service visit .

View the Thermador YouTube Channel to learn how to check your oven’s temperature (perform the bake test).
