Most Frequent Causes for Oven shuts off on its own

For the most accurate results, enter your model number.


Cause 1Thermal Fuse

If the oven gets too hot, the thermal fuse trips to shut off power to the oven. If the thermal fuse has blown, the oven will not heat. However, this is not a common occurrence. To determine if the thermal fuse is at fault, use a multimeter to test the fuse for continuity. If the thermal fuse does not have continuity, replace it. The thermal fuse cannot be reset—if the fuse has blown, it must be replaced.

Parts
Cause 2Touchpad and Control Panel

If an oven won't turn on, it's possible the touchpad and control panel is defective. One way to help confirm this is to determine if some touchpad buttons respond while others don't. If some of the buttons still work, then it's quite probable the touchpad and control panel is faulty and requires replacement (if none of the buttons work, a defective control board is more likely the cause of the oven not turning on).

Parts
Cause 3Incoming Power Problem

If an oven turns off on its own there could be an incoming power problem. Verify the circuit breaker hasn't tripped. Electric ovens require 240 volts of alternating current. Gas ovens require 120 volts. To determine if the electrical outlet is providing sufficient voltage, use a multimeter to test the incoming power at the wall socket.

Cause 4Control Board

The board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.

Parts
Cause 5Main Control Board

The main control board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.

Parts
Cause 6Oven Control Board

The oven control board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.

Parts
Cause 7Loose or Burnt Wire Connection

One of the wires that supplies power to the oven element or igniter might be loose or burnt out. These wires commonly burn out near the heat source. To determine if a wire has burned out, inspect the wires leading to the element or igniter. If a wire is burned out, it will often be visibly burnt.
