Ventilation

Usage & Operation

After installation, the hood does not work.

There are several solutions to this problem:

  • The power source is not turned on. If so, make sure the circuit breaker and the unit's power is on.
  • The powerline and the cable locking connector is not connecting properly. Check the power connection and make sure the unit is connected properly.
  • The switchboard and control board wirings are disconnected. Make sure the wirings between the switch board and control board are connected properly.
  • The switchboard or control board is defective. To have this fixed, contact Thermador Support at 800-735-4328.

There is no power at the power plug/socket.

To check if the power plug/socket functions, plug in other electrical devices and see if they work. If the power plug/socket does not function, check whether the residual-current-operated circuit-breaker (FI) or the domestic fuse for the electric circuit has tripped. The main fuse and residual-current-operated circuit-breaker (FI) are for your safety and respond if there has been an overload or short-circuit in the electric circuit. Check whether other appliances in the electric circuit have caused an overload. If required, contact an electrician.

There is insufficient air supply.

Open kitchen windows to create more air supply. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back drafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.

Local building codes may require the use of make-up air systems when using ducted ventilation systems greater than specified CFM of air movement. The specified CFM varies from locale to locale. Consult your HVAC professional for specific requirements in your area.

The hood does not vent properly.

There are several solutions to this problem:

  • The hood might be hanging too high from the cooktop. Adjust the distance between the cooktop and the bottom of the hood within 30" and 36" range.
  • Wind is affecting ventilation. Close all the windows and doors to eliminate the outside wind flow.
  • The duct opening or ductwork is obstructed. Remove all obstructions from the ductwork or duct opening.
  • The direction of duct opening is against the wind. Adjust the duct opening direction.
  • The ducting used is the wrong size. Change the ducting to at least 8” or higher.

There is excess smoke even when the ventilation is turned on.

Set a higher fan setting to extract more smoke.

The blower should be turned on for about 5 minutes before cooking in order to establish air currents upward through the hood or downdraft. Thus when heat, smoke, moisture, grease and cooking odors are produced, they will be carried outside instead of drifting into other rooms. Use the low speeds for normal use and the higher speeds for strong odors or fumes.

Drafts across the range or cooktop will reduce the effectiveness of the hood or downdraft. Such drafts should be prevented when possible.

The grease filters do not absorb the particles from the kitchen fumes.

The filters need to be cleaned. To clean the filter, make sure the appliance has cooled down. Switch the fuse off or pull the main plug. Never use any aggressive, acidic, or alkaline cleaning products. Clean the holder of the grease filters using a damp cloth and wash the metal-mesh grease filters in the dishwasher or by hand. Further information can be found in your owner's manual. Be sure to clean the metal-mesh grease filters approximately once every month for normal usage (1-2 hours daily).

The hood is vibrating.

There are several solutions to this problem.

  • The motor is not secure and needs to be tightened.
  • The blower wheel is damaged. To have this fixed, contact Thermador Support at 800-735-4328.
  • The hood is not secure. Make sure the hood is secure.

The metal filter is vibrating.

The metal filter is loose. Properly secure the grease filter to the grease tray.

There is a whistling sound coming from the exhaust air pipe.

The diameter of the exhaust pipe is too small. When you use the recommended duct size in the installation manual, the hood becomes quieter and achieves the optimum extraction result. Unfortunately, we cannot accept warranty claims for complaints that are attributed to the exhaust duct.

The downdraft ventilation whistles when retracted.

The appliance continues to run when retracted and the air is then pulled through increasingly smaller intake openings. This may result in a whistling sound. Switch the appliance off and wait until the run-on time has ended before you retract the hood. Low noise generation in this appliance is in accordance with the state of technology.

The light works but the motor is not turning.

If the motor is too hot to operate, the thermally protected system will shut the motor down. The motor will function properly after the thermally protected system cools down.

There are deposits in the housing in the exhaust air line.

Select a higher power setting and ensure that the pipeline slopes downwards to the outside. After cooking, leave the appliance running for a while to prevent condensation from depositing in the pipeline.

There are deposits and particles dripping from the hood.

High airflow speeds may cause fat particles to not reach the filter. The particles will bind together and drip from the filter after the hood is off. This does not impair the function of the hood. After cooking, clean the surface with a soft, damp cloth, and mild detergent.

There is residual moisture on the hood.

To ensure moisture does not collect on the appliance, switch on the fan before cooking to warm the surfaces. After use, leave the fan on to dry the residual moisture.

What is the Exhaust-Air Mode?

The hood fan draws the vapors produced during cooking into the hood, where they pass through the grease filter and out into the open air. The grease filter absorbs the grease contained in the vapors produced during cooking. The kitchen is kept virtually free from grease and odors.

Ducted fans must always be vented to the outdoors. To properly exhaust air, be sure to duct air outside. Do not vent exhaust air into spaces within walls, ceilings, attics, crawl spaces, or garages.

What is the Recirculating-Air Mode?

To operate in this mode, it is necessary to install a recirculation kit with an activated carbon filter. The hood fan draws the vapors produced during cooking into the hood, where they pass through the grease filter before the clean air is discharged back into the kitchen. The grease filter absorbs the grease while the activated carbon filter absorbs odors.

Do the filters collect germs, such as dirt mites, or those that cause allergies?

No, they are designed to capture grease particles. Additional cooking by-products, such as steam, heat, smoke, and odors vent outside the home through the ducting system.

What do CFM, sones and static pressure mean in relation to ventilation?

CFM: CFM stands for cubic feet per minute. The higher the CFM, the higher the air flow.

Sones: A sone measures the amount of sound that is perceived by a person. It is not the same thing as a decibel, which measures the intensity of sound. One sone is equivalent to the sound of a quiet refrigerator. The lower the sone, the lower the sound perceived.

Static Pressure: Static pressure measures the air flow resistance as air is moved through ductwork. This air flow resistance reduces the effectiveness of the ventilator fan. A fan must have the ability to overcome the static pressure to effectively move air through the duct.
