I went out to this customers house because they said their dryer was not heating at all. When I got there I unplugged the dryer, then used my multimeter to test the 240 volt wall outlet that the dryer was plugged into, my multimeter said 240 volts across the two 120 volt hot legs.
With the dryer still unplugged I then disassembled their dryer and ohm tested the heating element, my multimeter did not register anything(meaning my digital multimeter numbers did not change) when I touched each meter probe to the heating element terminals, so it was bad. The normal ohms should be 50 ohms or less when the heating element is good.
Here’s the heating element for this model:

Western Arizona Weather:
Clear. Lows 48 to 58. Northwest wind 5 to 15 mph.
Sunny and warmer. Highs 84 to 89. Northeast wind around 5 mph in the morning becoming northwest 5 to 10 mph in the afternoon.
The refrigerator was squealing very loud and it was coming from inside the freezer, I found the evaporator fan motor was squealing and shutting down in sequence, thus not cooling the freezer and refrigerator sections properly.
The evaporator coil had a thin layer of frost on it, which is normal, so the sealed system was working properly.
I replaced the evaporator fan motor, and it started working normal again.
Here’s the evaporator fan motor for this model:
Western Arizona Weather:
Mostly sunny, with a high near 79. North northeast wind around 5 mph becoming west northwest.
Mostly clear, with a low around 43. Northwest wind around 5 mph becoming calm.
The washer was not draining all the water properly, removed drain pump and noticed the impeller was not turning properly, the hoses to and from the drain pump were clear.
I replaced the drain pump, worked great!
Here’s the drain pump for this model:

“How To” video included in part link.
No cold air at all, compressor was not running, the compressor start device relay ohm tested good. Found the main control board was bad and not turning the compressor on.
Replaced the main control board and its FIXED!
Here’s the main control board for this model:

Unplugged dryer, ohm tested heating element to heater housing to check for grounded element, heating element ohm tested good, and not to the heater housing ground either.
Found stuck contact in timer causing this problem, Installed new timer, worked great!
Here’s the OEM timer I replaced for this model:
