Frequently Asked Questions

How can I determine if the heater element itself is faulty?

Disconnect power to the washer. Disconnect the wires from the heater element. Use a multimeter to measure the resistance across the heater element terminals. A reading of infinity (OL) indicates an open circuit, meaning the element is faulty. A reading of near zero indicates a shorted element.

Where can I purchase a replacement main control board for my GE washer?

You can purchase a replacement main control board from appliance parts retailers online, local appliance parts stores, or directly from GE's parts website. Be sure to have your washer's model number handy to ensure you get the correct part.

What is the typical voltage reading I should expect at the heater element when it's energized?

You should expect to see approximately 120V AC at the heater element when the heater relay is energized and the washer is calling for heat. Use a multimeter to measure the voltage across the heater element terminals while the washer is in a heating cycle.
