Thermador Range Won't Turn On
Range Won't Turn On is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
A tripped breaker or blown fuse
Worth ruling out first since it's the simplest and most common cause.
A failed power cord or internal wiring fault
Can develop over time, especially in units that have been moved or renovated around.
A failed control board
The unit may have power reaching it but a board failure prevents it from powering on normally.
Local conditions that matter here
This is the newest housing stock of any site in the network — barely 2.5% predates 1940 and 17.8% went up since 2000 — so the install is rarely the problem. When a cooking appliance fails here it is usually the appliance, not the opening it sits in.
