Hello, I just replaced the defrost heater with thermostat but I didn’t fully defrost all of the heavy frost off on the inner coils, is this necessary or will it freeze over again until I do so or will it defrost on its own with the new heater?

Hello David, Thank you for the question. Before installing the new part you should manually defrost the coils. We hope this helps!

How does the defrost heaters get it's power to turn them on?
For model number TFX20jrxdwh

Hi Lee, thank you for contacting us. The defrost timer, part number FIX310858, functions to shut off the compressor. When the compressor completes its interval, the defrost timer is on and allows power to turn on the defrost heater. We hope this information is helpful.

Major defrost issue
With the refrigerator unplugged, remove food, any racks in freezer and cover plates for coils and defrost timer (in fridge side). Defrost timer is simple: remove housing from rear wall, unplug timer and remove mounting screws. Install new timer (set timer so it is out of defrost mode -listen to the clicks or watch the video for assistan ce) and reverse process. Defrost heater is simple but may require more time. Use of hair dryer / heat gun may be needed to remove frost on coils. Each heater had two screws to hold to the coil frame and one shared electrical connector to attach to the main harness. Heater wires are positioned behind pinch points and behind the coils, so use of a reaching tool may help. Once the heater and accompanying thermostat (clips onto top coil) are removed install the new unit. Be sure to NOT touch the glass tube for the heater and position all wires properly. Reinstall all cover plates, racks, food and plug in, then wait 24hours for the refrigerator to do its job.

Frost build up in the freezer-cold air not reaching the fridge.
Pretty straight forward. Access the back panel of the freezer. Remove the 4 screws that hold the panel and the screws that support the light/ice maker cover. Pay attention to how things are wired and mounted. 4 screws a clip and an electrical plug will remove the defrost heater & thermostat. Mount in reverse order..from the bottom up. Ins tructions provided are somewhat helpful. Getting everything out of the freezer & removing the shelves will be the most time consuming.
