The cold storage side of this unit is not cooling well, 40º at best. Freezer is okay. Fans are working but can't isolate them or the dampers to check individually. There is a good frost pattern on the evap. The thermistors are the new type. Also, there is condensation on the lower to mid left wall.
I requested a service manual for this unit and received a mini-manual which does not help in putting it into service mode to check dampers, etc.. I tried the service mode procedure for the other dual evap units but that did not work. Any advice or service mode info is much appreciated.
This is a dual evap unit and the fridge side doesn't seem to be getting to set temp. It is cooling into the 40's, set at 37º. I put it into diagnostic mode: fans, thermistors, dampers and communication to the main board checked out okay. However I did get a fault in the communication between main control and dispenser, also duct door to dispenser wouldn't open in diagnostic mode yet it opens when dispensing ice normally. Dispenser is fully functional.
I also checked the 3-way valve operation, I could feel it moving so I assume it's okay.
I would guess that I need to replace the motherboard but I'm also wondering about the dispenser board. Any advice?
