The ice maker stop working on this 2-year old refrigerator. I have checked that water is flowing (water comes out of the water dispensor). Pulled the front cover off the icemaker and inserted jumper wire from T to H and the harvest mode initiated. Still not working. I suspect the ice maker water valve may be defective. Or it could be the ice maker thermostat. Any idea how to isolate the problem?
Answer Hello Steven,
The jumper from T to H bypasses the icemaker thermostat so it is not a consideration at this point. If you do this again with a test meter on the icemaker water valve terminals, near the end of the cycle there should be about 7 seconds that the meter should read 120Vac. If not, the contacts in the icemaker motor module are not passing voltage and the icemaker W10377151 will have to be replaced. If you do get the 120Vac for about 7 seconds, the water valve W10349187 is defective and will have to be replaced.
My freezer is frosted up, but nothing frozen, and fridge is not cooling at all.
Answer Hello Deepthunder. Make sure a door gasket is not leaking and letting warm air into the unit and frosting up everything. If not, It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the evaporator coils in the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the control board. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
