Replacing the fuse with a factory-rated replacement is important to safely restore full functionality. This prevents potential electrical hazards and further damage to other parts. 

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore microwaves.

This temperature regulator is the oven's thermostat. It senses cavity heat and cycles the heating source to hold the set temperature, helping restore accurate baking performance and more consistent cooking results.

• Monitors oven temperature via its sensing bulb/capillary and controls the heating circuit
• Helps maintain the set temperature during preheat and baking
• Common symptoms of a failed regulator: oven runs too hot or too cold, never reaches set temp, wide temperature swings, or won't shut off
• If the knob turns but temperature doesn't respond, the regulator may be faulty

• Disconnect electrical power before servicing; for gas models, also shut off the gas supply
• Access through the control area/back panel; note the original routing of the capillary tube and sensing bulb
• Handle the capillary tube carefully—do not kink or sharply bend; route and secure it in the original path and location
• Transfer the control knob and any mounting hardware from the old regulator if required, then verify proper shaft alignment before reassembly
