We need to replace this part. We can't find any instructions. Could we have your help to install it.
To replace the defrost heater, you will need to disconnect power to the unit. Remove the shelving in the freezer compartment. Take the rear cover off the back of the freezer compartment. Unplug the connector at the top for the heater and thermostat assembly and take out the 2 screws that hold the heater in place and remove. Reinstall in reverse.
The defrost does not work. Is this the only part I need to change or there are others parts I need to check out?
Answer Hello Peter. If the heater and the thermostat WR51X10029 are open, then this will be the only part you will need for the repair. If they are closed, then you may have a bad defrost timer WR9X489. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
