Frigidaire Oven won't turn off: Common Causes & How to Fix
1Range/Stove/Oven Touchpad and Control Panel
Most Common Solution
Repair Instructions:
If your oven won't turn off, the touchpad might be broken or not working right. To check this, first turn off the power to let the oven cool down. Then unplug the touchpad ribbon from the control board. Turn the power back on and see if the oven turns on without the touchpad ribbon connected. If the oven doesn't turn on, the touchpad is probably the problem and you'll need to replace it.
How to Replace Range/Stove/Oven Touchpad and Control Panel
-
Disconnect power by turning off the circuit breaker for the cooktop/stove/oven.
-
Remove any retaining screws around perimeter of the control panel faceplate.
-
Carefully pry off faceplate using a plastic putty knife or thin-blade tool.
-
Disconnect wire harness connecting control functions to main control board.
-
Remove mounting screws attaching the touchpad directly to the appliance frame.
-
Withdraw old touchpad and controls once fully detached from mounting points.
-
Clean mounting surfaces where the new assembly will contact the appliance housing.
-
Mount replacement touchpad using retaining screws through holes in its mounting bracket.
-
Reconnect wire harness by plugging it back into the correct port on new touchpad.
-
Replace control panel faceplate and restore power to test operation of new controls.
2Range/Stove/Oven Temperature Control Thermostat
Most Common Solution
Repair Instructions:
The temperature control thermostat in an oven keeps track of the heat inside and turns on the heat when the temperature drops too low. If the thermostat is broken, the oven might not heat up. But this doesn't happen often. Before you replace the thermostat, you should check parts that break more often, like the igniter and the bake and broil elements. If those parts are fine, the thermostat could be the problem. Testing the thermostat can be tricky. If you think the thermostat is broken, you should replace it.
How to Replace Range/Stove/Oven Temperature Control Thermostat
-
Disconnect power supply - Locate the circuit breaker for the oven and switch it off before starting work. This prevents electric shock.
-
Remove control knobs - The knobs on the stovetop need to be removed to access the thermostat. Gently pull them straight off the stems.
-
Take off backguard - Unscrew any screws or brackets on the backguard and remove it to access the rear of the thermostat.
-
Disconnect wiring - Identify each thermostat wire connection and remove them. Tape wires to keep organized for reassembly.
-
Unmount old thermostat - Remove mounting screws to detach the old thermostat from the oven. Be careful not to lose any parts.
-
Install new thermostat - Secure the new thermostat in place with mounting screws. Make connections to match old wiring.
-
Replace backguard - Carefully reattach the backguard with the screws and brackets. Make sure wires are secure.
-
Reattach knobs - Line up the knobs and gently push back onto the control stems until fully seated.
-
Restore power - Return to the circuit breaker and switch the oven power back on.
-
Test operation - Set oven to various temperatures and verify accurate readings. Calibrate if needed per manufacturer instructions.
3Range/Stove/Oven Bake Element
Most Common Solution
Repair Instructions:
Sometimes, the heating element in the oven can burn out and short out to the oven's inside. If this happens, the oven won't turn off. You can often tell if the bake element has shorted out because it will look damaged. Check the heating element for any holes or blisters. You can use a multimeter, which tests the flow of electricity, to see if the bake element has shorted out. If the bake element doesn't have continuity, meaning electricity can't flow through it, you should replace it.
How to Replace Range/Stove/Oven Bake Element
-
Disconnect power supply - Locate the circuit breaker for the oven and switch it off before starting work. This prevents electric shock.
-
Remove oven racks - Take out all racks and accessories to clear the way to the bake element.
-
Locate mounting screws - The bake element is held in place by mounting screws accessible from the rear. Remove these screws.
-
Disconnect wires - Detach the electrical connectors from the terminals on the ends of the bake element. Make note of wire positions.
-
Extract old element - Gently slide out the old bake element, being careful not to damage the ceramic insulation.
-
Install new element - Carefully insert the replacement bake element into the oven cavity along the same path as the old one.
-
Reconnect wires - Attach element connector wires according to notes from disassembly to match original configuration.
-
Remount element - Insert mounting screws to securely fasten the new bake element into place.
-
Replace oven racks - Return all racks and accessories to their original positions within the oven.
-
Restore power & test - Turn circuit breaker back on. Turn on oven to verify proper heating operation.
4Range/Stove/Oven Broil Element
Most Common Solution
Repair Instructions:
If the broil element in the oven is shorted out, meaning it has a break in the flow of electricity, the oven might not turn off. Often, a shorted out element will look visibly damaged. Check the broil element for holes or blisters. You can use a multimeter, a tool that tests the flow of electricity, to check if the broil element is shorted out. If the broil element shows continuity from the terminals to the outer case, it means it's shorted out. If the broil element is shorted out, you should replace it.
How to Replace Range/Stove/Oven Broil Element
-
Disconnect power supply to the range at the main circuit breaker for safety.
-
Remove broiler/top oven panels by lifting out mounting clips or screws.
-
Carefully pull broil element shelf out to fully access element wires.
-
Detach wire leads from element by loosening screwdriver terminal screws.
-
Slide old broil element out of mounting slots at rear of broiler box.
-
Insert replacement element leads first through access hole before sliding into slots.
-
Tighten terminal screws to securely connect wires to new element.
-
Slide shelf back into position below element and replace panels.
-
Reconnect power supply at main breaker and test broiler function.
-
Replace any insulation blankets or heat shields removed during replacement.
5Range/Stove/Oven Oven Control Board
Most Common Solution
Repair Instructions:
The oven control board uses relays, which are like switches, to send electricity to the bake and broil circuits based on how you set the oven and what the sensor detects. If one of these relays gets stuck in the 'on' position, the control board might keep sending electricity to the heating circuit. If the oven keeps heating even after you turn it off, the control board is probably broken. If the control board is broken, you should replace it.
How to Replace Range/Stove/Oven Oven Control Board
-
Shut off power to the range by locating the circuit breaker and shutting it off. This prevents electric shock.
-
Remove the control knobs by gently pulling straight up and off of the stems they attach to. Set aside.
-
Remove the control panel of the oven by locating mounting screws around the edges and carefully removing them.
-
Disconnect the wire connectors attached to the control board by squeezing release tabs and gently pulling wires free.
-
Remove mounting screws or other hardware securing the board in place. Lift out the old board.
-
Install the new control board and attach with original mounting screws or hardware.
-
Reconnect wire connectors to matching terminals, ensuring colors or locations match up properly.
-
Replace the control panel and mounting screws around the edges.
-
Reattach control knobs by pushing them back onto the stems.
-
Restore power and test ovent functions like bake, broil, temperature controls.
6Range/Stove/Oven Touchpad
Most Common Solution
Repair Instructions:
If your oven won't turn off, first unplug it or cut the power and let it cool down. Then, remove the touchpad ribbon from the control board and turn the power back on. If the oven doesn't start heating up once the touchpad ribbon is disconnected, this suggests that the touchpad is probably broken and you'll need to replace it.
