While on the bake setting my Kenmore oven heated up, but only on the broiler element. The display read E2 F3 and I couldn't shut the oven off. I eventually had to turn the breaker off to stop it. Do I need a new temperature sensor or is it something else?
Answer Hello Joe,
The E2-F3 error code indicates that the electronic oven control board in the range senses an over-temperature condition in the oven, (known by technicians as "runaway temperature"). This can be caused by a temperature sensor probe 8273340 out of tolerance, a wiring problem between the sensor and the control board, or an electronic control board relay failure. If the oven is not heating when this error code appears, (unit not turned on), then you probably have an out-of-tolerance temperature sensor probe. To test with an ohm-meter, it should read about 1100O at room temperature, (70°F). If the oven is overheating, then you likely have a stuck relay on the electronic oven control board 8523665.
The oven doesn't stay on. It keeps turning off. Please advise.
Answer Hello Jun,
This sounds like a bad connection. Once the control is set, the relay continues to pass the current until the primary voltage to the relay is discontinued. This will only happen when the off button is pressed or something else stops the voltage supply from being available to the primary relay coil. I would start at the breaker and work toward the unit. I have found many issues with the receptacles and power cords are losing connection. The power cord will lose connection at the terminal block if the nuts are not tightened sufficiently. If the receptacle is losing connection, there will be a burned spot on one of the prongs that go into the receptacle.
