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:

The customer complaint was the dryer was very noisy, I ran the dryer and did confirm it was extremely loud when the drum was turning. I unplugged the dryer and disassembled it and found two of the drum rollers were bad and worn out, wobbling on the roller shaft. The roller shaft also had metal shavings on the dryer base.
I replaced all four rollers and roller shafts, it’s always best to replace all four at once. After I replaced them it sounded like a normal dryer running.
Here’s the roller and shaft assembly for this model:

Western Arizona Weather:
Sunny, with a high near 100. Breezy, with a south southeast wind around 15 mph, with gusts as high as 20 mph.
Clear, with a low around 63. Breezy, with a south southwest wind 10 to 15 mph becoming southeast after midnight.
I found the customers dryer vent clogged on the outside of their house, which caused the thermal cut-off, which is located on the heating element housing, to go bad.
I cleaned their outside exhaust vent, and cleaned their entire vent hose exhaust in the back of the dryer of all lint.
I unplugged the dryer, then disassembled the dryer and removed the drum to get better access to it, then I ohm tested the thermal cut-off and I got no continuity on my multimeter. I also ohm tested the heating element and the high-limit thermostat and both ohm tested good.
I replaced the thermal cut-off, reassembled the dryer, plugged it in, and it started heating normally again.
Here’s the thermal cut-off(also called a thermal fuse) for this model:

I went out to see why this refrigerator wasn’t cooling. I found that the condenser fan motor, that’s located in the very back of the refrigerator, wasn’t running and blowing air. It had stopped running and I was getting 120 volts to it.
Also due to the condenser fan motor not running it overheated the compressor start relay and made that go bad too. So I replaced both parts and it worked great!
Here’s the condenser fan motor for this model:
