Whirlpool WP67004188 Defrost Heater (Evaporator) OEM Part

Ended up being the defrost sensor. Ordered the heater and control board just in case. Started with the control board still didn't defrost. replaced the sensor and all is well. Super helpful tech staff answered all my questions...

Replace defrost heater and switch. Tested outside of limits of resistance

I replaced the heater, evap and thermostat, defrost. I watched your easy to understand videos and it was pretty easy, the hardest part was getting the screws off the panel inside the freezer.

I checked for continuity with an OHM meter. Defrost thermostat was good. I then replaced it any way since the unit is old, the problem was the heater evaporator but this is the advice . Take it out of the unit and check for cracks or any visible damage. I checked mine it was giving me a good reading, but when I took it out of the unit I saw a tiny crack right on the tip and replaced it for a new one and fixed the problem and my return was hassle free. Thanks appliance parts pros.

I actually ordered the part from Sears online first. It ended up it was on backorder from their supplier. I ordered it from appliance parts pro and got it in about 2 or 3 days. I have a maytag side by side refeigerator and it was tripping my gfci outlet in my garage. The problem was a defeost unit on the condensor. I had to remove the shelfs and every removable part.. (Ice tray, ice tray mechanism and light bulbs) then i removed the rear panels on the inside... I unsnapped the condensor, unplugged the defeost element which either wraps around the condensor or in my case was at the bottom of the condensor... Once i unplugged the element i plugged the refeigerator in and the gfci didnt trip... To further investigate the problem i just took a meter and checked the resistance. When the new part came in, i just installed it and everything i took apart. It works like a champ now.
