Troubleshooting a Whirlpool Gas Oven That Won't Shut Off

Check the controls for your oven. Some modern Whirlpool ovens come with a touch pad control instead of dials. If the oven won't shut off when you press the "Power" button, there could be faulty material used in the control pad. Try pressing other buttons on the control pad to see if the oven responds. If the problem is the control pad, it will need to be replaced. If it isn't, proceed to the next step.

Check the controls again to ensure that the oven is indeed in manual control. If it is set to an automatic function, this could be the reason the oven won't shut off. Consult the manual for your particular model Whirlpool to find out how to change modes on the oven.

Pull your Whirlpool oven away from the wall so you have access to the rear panel. Unplug the oven from its power source or shut the main breaker switch off.

Remove any screws holding the panel in place and remove the panel. Locate the cycling relay in the oven. This is the circuit board where all the wires connect.

Unplug the wires from the relay terminals and turn on your voltmeter. Set the dial to read in ohms.

Plug the oven back in and touch the red "+" lead to the relay terminals. There should be no continuity displayed on the voltmeter when testing any other terminals than the terminals marked "S" and "R." If there is continuity, the relay is likely damaged and will need to be replaced. If this isn't the issue, unplug the oven, replace the wiring in the terminals and proceed to the next step.

Locate the thermostat in your oven. This is likely located next to the cycling relay, but you may need to consult your user's manual to be certain.

Unplug the wires connected to the thermostat.

Plug in the oven and touch the terminals on the thermostat with the red "+" lead of the meter. Hold the lead in place. If there is no reading produced on any of the terminals, the thermostat is likely broken and needs to be replaced.
