In Topic: GSH22JFREWW - Evaporator Fan Motor Not Coming On

Today, 10:39 AM

The yellow wire is the pulse width modulated (PWM) speed signal from the  muthaboard to the motor's internal inverter. It's a square wave signal of varying length pulses according to how fast the muthaboard wants the fan motor to run. The effective voltage on the yellow wire varies as the length of the square wave increases.

 

The actual driving voltage that the internal inverter uses to run the BLDC motor is supplied on the red wire. That's why when you hot wire the motor, both the red and yellow wires are tied to +Vcc-- with the yellow wire tied to a steady +Vcc power supply, it's as though the muthaboard is sending the command to the inverter board, "Make your speed max RPMs." 

 

Your hot wire test conclusively proved that the motor's internal inverter is fried. What we don't know at this point is whether or not the main board is also bad since, as Brother Durham pointed out, bad fan motors have a nasty habit of taking out muthaboards in GE fridges.

Given the age of this machine, you will probably need to replace the damper pads at the base of the transmission. This is a visual check-- remove the front panel and push the tub back to see if the pads are still in place. Part number: AP4024203

The Fast Track tells you everything you need to know for diagnostics. The service manual is really only good for disassembly, which is pretty standard and straight-forward for most Samsung dryers. This video covers the main disassembly steps for the model you'll be working on:

That explains it. Maybe we can cross it over to an Ameedican model number if you can post a part number of something from the dishwasher like the control board.
