I was a Building Contractor along with owning rental properties where I did most of the repairs myself. Its my pleasure to pass on to you some of the methods I had used in the past. Hopefully, this will save you the expense of hiring a professional to do the work.

Electric Oven Troubleshooting



 Electric oven troubleshooting consists of checking the heating element, temperature sensor and infinite switch to determine which item is malfunctioning.

Steps in Electric Oven Troubleshooting:

1. Test the element

Remove the two screws holding the element in place. Using an ohm meter, attach one test probe to one of the element terminals and the other probe to the remaining terminal and check for continuity.  If the  reading is high, the element has good continuity and is funtioning well.

2. Check the temperature sensor

The sensor is located at the rear wall near the top of the oven. Remove the two screws holding the sensor and carefully pull the sensor wire and connector through the hole enough to disconnect it. If the mounting screws are not exposed at the rear wall, or the connector wire could not be pulled through the opening, it will be necessary to remove the back panel from the range to remove the sensor.

After setting an ohm meter to its lowest setting, place one probe into one side of the sensor connector and the other probe into the other side. Ideally the ohm reading should be approximately 1080 ohms at room temperature. If the reading is not near this figure, replace the sensor.

3. Test infinite switch

The next major component in electric oven troubleshooting is the infinite switch. On the back of the switch are 5 terminals, L1,L2,H1,H2, and P. Unhook each wire individually and mark the location as imprinted on the switch surface using tape or other means. Set the test meter to the Rx1 scale and set the meter at zero. With the infinite switch turned to the on position, attach one of the test leads to L1 and the other to P terminal.  You should get a high reading showing good continuity.

Do the same with L1 and H1, and L2 and H2 terminals. You should get a high reading with these tests as well. Next, with the switch placed in the off position, attach the test leads just as before. This time all the readings should be at zero showing no continuity. If you did not get the required test results, the switch must be replaced.  This is the final check in electric oven troubleshooting.
