Troubleshooting F30 and F31 Error Codes on a Range

See the written article that matches this video here: https://www.searspartsdirect.com/diy/...

This video from Sears PartsDirect will show you what to do when your range flashes an F30 or F31 error code. You might see this code when you try to bake or broil. For Kenmore and Frigidaire ranges like this one, these codes mean that the control detects a problem with the oven temperature sensor probe.
The 3 parts that can trigger this code are the oven temperature sensor probe, a wiring harness or the electronic oven control board. In this video, we’ll show you how to figure out exactly what’s wrong so you can get back to cooking.

Unplug the range and pull it out of the cabinet. If you have a gas range, shut off the gas supply. Remove the screws and pull off the top and the bottom back panels. First make sure the sensor probe is fully plugged into its wire harness. If the connection is loose, tighten the connection and reassemble the range. Restore electrical power to see if the code disappears. If it does, you fixed the problem by tightening that wire harness connection. If the code appears, let’s check the entire sensor circuit through the purple wires that connect to the control board. Unplug the wire harness with purple wires from the control board. With your multimeter set to check resistance, measure the resistance through the purple wires on the connection plug. It should measure around 1,080 ohms at room temperature. If you get near 1,080 ohms of resistance, the oven temperature sensor probe and its wiring are likely okay. But you’ll need to check for a ground to the metal range cabinet, which can also cause an F30 or F31 code. Check for resistance from each purple wire to metal on the back of the range. If you measure 0 ohms of resistance between one or both purple wires and the metal cabinet, that means a damaged wire is creating a short. Find and repair the wire damage that’s allowing bare sensor wiring to touch the metal cabinet. If you measure OL between each purple wire and the metal cabinet, there is no short and the wiring is okay. You’ll need to replace the control board because you’ve ruled out all other possible failures. Take a look at our video “Replacing a Range Oven Control Board” for more help. Now, if you didn’t measure near 1,080 ohms through the purple sensor wires that connect to the control board, a broken oven temperature sensor probe or a wiring failure is causing the F30 or F31 code. Let’s check the sensor first. Unplug the sensor from the wire harness and check the sensor resistance by placing the meter probes into the harness plug. If you don’t measure near 1,080 ohms, replace the oven temperature sensor. Our video “Replacing a Temperature Sensor in an Electric Range” will show you how. If you do measure near 1,080 ohms of resistance through the sensor, replace the wire harness because it’s keeping the control board from measuring the proper sensor resistance. Once you replaced the problem part, reinstall the back panels and plug in the range. The error code should be gone. That means you fixed the problem and can get back to baking!
