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.

How To Repair An Electric Range



The three most common failures in an electric range are the infinite switch, the heating element, and the oven temperature sensor.  You can easily learn the basics in how to repair an electric range by following the procedures listed below. Before doing any work on the range, first unplug the range or turn off the circuit breaker at the breaker box.

BURNER FAILS TO HEAT

When the surface burner fails to heat properly, do the following:

1. Check the electric range burner

Remove the burner from the receptacle and install a working burner. If this burner is not heating, it indicates that either the infinite switch or the burner receptacle is defective. If another burner is not available for this test, using an ohm meter, attach one test probe to one of the burner 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. Exam burner receptacle

Look for charring on the electric range burner receptacle or burnt wires. If either is found, replace the receptacle. If the receptacle and attaching wires appear to be in good shape and the burner is making good contact in the socket of the receptacle, it’s time to check the infinity switch.

3. Test infinite switch

On the back of the electric range infinite 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. 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 proper test results, the switch must be replaced.

OVEN NOT HEATING

If the oven bake or broil electric range element fails to heat, or is not heating at the proper temperature, perform the following tests:

1. Test the element

Remove the two screws holding the element in place. Perform the same procedure as was performed when testing the burner. If the element passes the test, go to the sensor.

2. Check the temperature sensor

The temperature 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 oven infinite switch

Test the electric range oven infinite switch just the same as the test for the burner infinite switch explained in number 3 above.
