How does one remove the back panel inside the freezer to access the bi-metal AP4310486?
Answer Hello John. First you will need to remove the basket and the freezer door from the unit. Once these are removed, you will then remove the icemaker from the side of the freezer compartment. Then remove the screws securing the back wall to the unit. In the center of the back wall there is a vent. To remove the vent, there is a clip in the slot on the bottom that needs to be released to remove the cover. Once you remove the center cover, you will need to remove the cover on the right side and remove the thermistor from the cover. Once all of this is removed, you should be able to remove the back panel and access the bi-metal W10165425.
Can I get to the Bimetl - Def through the back panel?
Answer Hello John. Yes, you will need to remove the back panel inside the freezer to access the bi-metal W10165425. It is located on the freezer coils.
Hi-I have a Whirlpool refrigerator as indicated above and the bottom freezer acumulates ice on both the evaporator coil as well as a bit inside the cabinet. Someone had previously replaced the bimetal defrost due to the same problem. My question (s) are, what generally causes the freezing on the evaporator, since I checked continuity on the defrost heater and it shows that it is good (continuity, low ohms reading)? Should the bimetal defrost t'stat show normally open or closed when exposed to higher temps, and does this initiate the defrost cycle when it opens or closes? Also, since someone else repaired the refrigerator before me, I found no clip on the bimetal t'stat, therefore it was not coming in direct contact with the evap coil. What is the exact location the new bimetal t'stat should be when I replace it? I am actually a plumbing/HVAC contractor with extensive diagnostic experience in the field, but just a bit rusty on the nuances of refrigerators. Any and all complete comprehensive replies would be greatly appreciated. Thanks!
Answer Hello Mark. If the bi-metal W10165425 is cold, it should read closed. If it is hot, it should read open. The Bi-metal attaches to the top of the evaporator assembly on the large copper line. If the bi-metal and the heater test good, you will need to replace the control board 12784415. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter.

IS THIS THE HEATER FOR DEFROST?
Answer Hello Alan. No, W10165425 is the bi-metal defrost. 67002493 is the defrost heater. Hope this helps.
