I’ve tested continuity between thermostat and heater, Check OK. Power seems to come from control board, no timer. I need a wiring diagram to verify. Also, found a TSB for an evap fan that could cause similar issue, says to NOT REPLACE BOARD. Anyone run into this?
Continuity Check of components and defrosting evaporator (frosted up in a day)
- Guest asked 5 years ago
Hello
There is one service bulletin on warm fresh food temperatures. If you have a part of your defrost system that is not functioning, it will take 4-6 days to frost up the evaporator. If the evaporator fan is not moving enough air or stops intermittently it will cause a frost build up on the coil within one day.
( Service Bulletin )
Replace the fresh food evaporator fan with part WR60X29099. The new fan is a
direct replacement for the original and does not require software to be updated (updating the
software with NewFI or with a SUM is no longer required for this repair). When the original
fan part number is ordered it will supersede to the new part number (WR60X29099).
