Independent repair, not a factory service center
TrueFix San Antonio is an independent repair company, not a Thermador service center. If your microwave is still under the manufacturer's warranty, contact Thermador first, since warranty work normally has to go through their own service network.

Thermador microwave repair: what to know
Thermador microwaves are built-in models: microwave drawers set under a counter or wall oven, and built-in microwaves or speed ovens stacked with a wall oven. The drawer moves on a motorized drive, so a drawer that hesitates or reverses points to the mechanism, its sensors or debris in the track. Speed ovens pair the microwave with convection heating on a separate circuit. Heating faults involve high-voltage parts that stay charged after the power is off.
Common Thermador microwave failures
These are the failure points to check first on a Thermador microwave:
- Microwave drawer drive or position sensor failure
- Door interlock switch failure on built-in units
- Magnetron or high-voltage diode failure
- Convection element fault on speed ovens
- Touch control panel unresponsive
A list like this points the diagnosis in the right direction, but one symptom can come from parts at very different prices, so the cause is confirmed at your home before you get a quote.
How we diagnose a Thermador microwave
Whatever the brand, on a microwave we check the door interlock switches before anything else — they fail more than any other microwave part and they're also the safety cutoff, so nothing further gets tested until they check out.
One microwave symptom that's easy to misread is a microwave that lights up, turns and hums but leaves food cold, which feels like a total loss but usually means a failed magnetron, high-voltage diode or capacitor, not the control board.
Built-in Thermador equipment: what the visit involves
Most Thermador equipment is built into cabinetry or anchored in place, so the visit starts with working out how to reach it. We allow a longer appointment and protect floors, cabinet faces and countertops before anything moves.
It changes the economics as well. Replacing a fitted Thermador microwave usually means cabinet or countertop work on top of the new appliance, so a failure that would retire a freestanding unit is usually still a repair here.
Before the visit
The model and serial number are inside the door frame, or on the back or side of the cabinet. A photo of that label is the most useful thing you can send when you book: it tells us which Thermador platform you have and which parts to bring.
Check the breaker and make sure the door latches firmly. If it runs but doesn't heat, stop using it: the fault is in the high-voltage section, which isn't a do-it-yourself repair.
In San Antonio, keep in mind over-the-range microwaves in builder kitchens that double as the range vent, where the grease filters and exhaust fan become part of the job.

The drawer's motor and sensors stop it when they detect resistance, so check the track and the floor of the cabinet opening for anything catching. If it still stalls, the drive gear, motor or position sensors need testing.
Not usually. A built-in microwave slides out of its trim kit separately from the oven above or below it. The trim and mounting screws are removed carefully so the finish isn't marked.
The two functions have separate power circuits. A failed magnetron, diode, capacitor or door switch stops microwave heating while the convection element keeps working. These high-voltage parts can hold a charge, so they need a technician.
The part, and whether it's an over-the-range or built-in unit that has to come off the wall or out of the cabinet. Door switches and turntable motors are small parts; magnetrons and control boards cost more.
