Thermador Appliance Repair Service

Who makes Thermador

Thermador is a brand of BSH Home Appliances, the same company that makes Bosch and Gaggenau appliances and has been wholly owned by Robert Bosch GmbH since 2015. Thermador is BSH's US luxury line, covering pro-style ranges and rangetops with Star burners, Freedom induction cooktops, wall ovens, dishwashers, ventilation and column refrigeration. Thermador and Bosch share engineering and parts channels, and some Thermador products appear to be built alongside their Bosch counterparts.

What tends to fail

Thermador ranges and rangetops come in most often for burner problems: a Star burner that will not light or keeps clicking, which is usually an igniter, a spark module or a wet burner cap, and gas ovens that heat slowly or not at all, which tends to be the oven igniter. Electric and dual-fuel ovens fail at the relay board, control module, bake element or convection fan, and the heavy oven doors wear out hinges and springs. The repair involves lifting the cooktop or pulling the range, testing the ignition circuit or the element, and replacing the failed component.

Freedom induction cooktops usually fail at a power module or the touch control, and the glass can crack from impact. Column refrigerators and wine columns are built in and heavy; fans, defrost faults, ice makers, control boards and door gaskets are the common calls, and a compressor or refrigerant fault is a sealed-system job. Thermador dishwashers share the Bosch platform, so drain pumps, heat pumps and door latches lead the list there. Ventilation hoods mostly need blower motors, switches or lights.

Parts

Thermador parts come through BSH's US parts channel, the same source as Bosch, and many dishwasher and oven parts are shared across the two brands. Range-specific items such as burner heads, spark modules and oven doors, and refrigeration parts for column units, are more often special order with a longer wait, and some are only sold as assemblies. The technician reads the full E-Nr off the tag, confirms the part against it and quotes it before placing the order.

Finding the model number

Thermador tags show an E-Nr and an FD production number. On pro ranges the tag is usually behind the kick panel or storage drawer, or on the frame inside the oven door; on rangetops and cooktops it is underneath the unit, so there is often a duplicate on the cabinet or in the owner's packet. Wall ovens carry it on the frame behind the door, dishwashers on the top edge of the door, refrigerator and wine columns inside on a side wall or behind the top grille, and hoods behind the filters. Send a photo if you can get to it.

Error codes

Thermador ovens and dishwashers show E-codes in the same style as Bosch. Our pages on Thermador oven codes and Thermador dishwasher codes cover the common ones. Cooktops, refrigeration and hoods have their own code sets that vary by model, so note the code and when it appears and give it to us when you book. The technician checks the code against the service data for your exact E-Nr before deciding on a part.

Built-in refrigeration and pro ranges

Most Thermador refrigeration is a built-in column or an integrated unit with a cabinet panel, and the ranges are heavy units set into cabinetry. Both need extra time and sometimes a second person to pull, and column refrigerators are weighed down further by their panels. Tell us when you book whether the unit is panel-ready, how the toe-kick is attached and whether there is room to move the range, and we schedule the visit accordingly.
