When I arrived I pulled the refrigerator out from the wall, then unplugged the refrigerator, then removed the compressor start relay from the side of the compressor and used my digital multimeter to ohm test it, I set my meter on 200 ohms, and my meter’s numbers didn’t change when I ohm tested it, and that means its bad.
Normal ohms should be 12 ohms or less, usually around 5 ohms. I installed a new compressor start relay and the compressor came right on and started cooling. I also cleaned the customers condenser coil. located underneath the front of the refrigerator, behind the kickplate grille.
Here’s the compressor start relay for this model:
When I arrived there was no ice at all in the ice bin that’s located directly under the ice maker. I removed the front cover, just unsnaps off, and turned the gear in the direction of the arrow, then it started cycling on its own and it put water in towards the end of the cycle.
The freezer was at 5 degrees which is good. I told the customer I would call him later that evening to see if it dumped the ice out, So four hours later I called the customer and he said no ice had dumped into the ice bin, I ordered a new ice maker and went out to install it, and he called me back saying the new ice maker dumped the first batch of ice.
Here’s the ice maker for this model:

I went out to this refrigerator and found the back panel inside the freezer had massive frost build-up on it. I first unplugged the refrigerator from the wall electrical outlet, then ohm tested the defrost heater and found it was bad, meaning the numbers on my digital multimeter didn’t change. Normal ohms for most at defrost heaters is mainly about 30 ohms or less.
I completely defrosted the entire evaporator coil, which is located behind the back panel in the freezer, then I removed the old defrost heater assembly and installed the new defrost heater assembly, worked great!
Here’s the defrost heater assembly for this model:

When I arrived the back panel inside the freezer has massive frost buildup on it. I unplugged the refrigerator from the wall outlet, then ohm tested the defrost thermostat while it was frosty and the heating element, both ohm tested good.
I ordered and replaced the adaptive defrost control board and it worked great!
Before the adaptive defrost control board is replaced its a must to defrost the entire evaporator coil from top to bottom.
Here is the adaptive defrost control board for this model:

When I arrived I opened the freezer door and there was massive frost build-up on the back panel inside the freezer. I Unplugged the refrigerator from the wall outlet, then I got my heat gun and started defrosting it, then I removed the back panel inside the freezer and continued defrosting the evaporator coil.
I noticed a bulge on the top of the defrost thermostat, and ohm tested it while it was still covered in frost and I got no ohms reading at all, so it was bad and the cause of this problem.
Here’s the defrost thermostat for this model:

Mostly sunny and breezy. Highs 71 to 76. North wind 15 to 25 mph.
I removed back panel in the freezer and found lots of ice clogging up the air vents going to the refrigerator section, and ice clogging the drain line below the freezer evaporator. I de-iced it all, it took awhile to do, but it has to be done before the refrigerator will cool properly again.
I saw the evaporator fan wasn’t running in the freezer, so I removed the electrical connector from it and used my multimeter to see if it was getting 120 volts to it, and it was. So I replaced the evaporator fan motor and it started blowing cold air.
Here’s the evaporator fan motor for this model:
