The freezer is running at -20f, the ref side at 37f. The evap freezes up. Blocks the drain and water collects and freezes on bottom of freezer compartment. Ran diagnostics. All check out but test 5. Damper runs but doesn't close and evap fan doesnt run on test 5. Parts breakdown doesn't show freezer thermister as does wiring diagram on unit. I have changed the main electronic control board. Same results. Sometimes the over temp alarm activates. Any ideas?
ANSWER Hello Tony,
The thermistor for the freezer is located by the air duct and comes in from the refrigerator side under the diffuser. The thermistor part number for diffuser is 2188819 and is the same as refrigerator thermistor. The drain through freezing the drain line would normally be a clogged drain. Clear ice and drain line if continues then you will want to make sure that the fan is not coming on during the defrost cycle.
