When your Tappan oven turns off by itself, the touchpad is the most likely cause, especially if some buttons respond intermittently or not at all. A faulty touchpad can make the oven shut down during baking or prevent it from starting again. Next, check the thermal fuse. If the oven overheats, this fuse can trip and cut power, and a blown fuse must be replaced because it cannot be reset. Use a multimeter to test it for continuity. A defective touchpad and control panel can cause similar symptoms when some buttons work but others do not. If the oven has no power at all, verify that the circuit breaker has not tripped before replacing parts. Less commonly, loose or burned connections, failed relays, or an internal fault in the Tappan control board or main control board can interrupt power to the oven. Always disconnect power before testing or repairing your range. Enter your model number to find the exact replacement touchpad, thermal fuse, control panel, or control board for your Tappan range, stove, or oven.
01 - Tappan Range/Stove/Oven Touchpad
If the oven turns off on its own, determine if some of the buttons on the touchpad respond intermittently or not at all. If so, it's likely the touchpad is faulty and should be replaced.

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.
03 - Tappan Range/Stove/Oven Touchpad 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).
If an oven turns off on its own there could be an incoming power problem. Verify the circuit breaker hasn't tripped.

05 - Tappan Range/Stove/Oven Control 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.
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.
