When your Frigidaire oven turns off by itself, the touchpad is the most likely cause, especially when some buttons respond intermittently or not at all. A faulty touchpad can make the oven shut down or stop accepting commands and usually needs replacement. A tripped or blown thermal fuse is another possibility. The fuse can trip if the Frigidaire oven gets too hot, and it cannot be reset. Disconnect power, then test the thermal fuse for continuity with a multimeter. If it has no continuity, replace it. A defective touchpad and control panel can also cause an oven that keeps turning off, particularly when some buttons work and others do not. Next, check for an incoming power problem, including a tripped circuit breaker. If those parts check out, inspect the control board and main control board for loose or burned connections, failed relays, or other damage. These boards distribute power to the oven components and may need replacement. Whether your Frigidaire oven shuts off while baking or turns off by itself, enter your model number to find the exact replacement part for your specific range, stove, or oven.
01 - Frigidaire 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 - Frigidaire 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 - Frigidaire 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.
06 - Frigidaire Range/Stove/Oven Main 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.
