George for Model Number GSH22JSXLSS My chilled water line was iceing up so I replaced the dispenser water tube heater which had corrected the issue in the past. This time the problem remained so I checked all the connections to the heater and found them to be good. I than checked the voltage to the tube heater and found 0 volts. I also checked the voltage at pins 2 & 6 on the PCB and found that to be 0 also. all other functions and lights on the PCB and refrigerator appear to be working properly. It would appear there is no power going to / from pin 2 on the PCB. Is this a bad PCB or is something else I should be looking at?
Answer George, With no voltage on the 2 and 6 pins, the dispenser control board would need to be replaced. WR55X23210 Read More... Answered by AppliancePartsPros.com | Monday, April 6, 2020
