The low ambient heater is drawing less current than expected. Either the heater or wiring is open circuit or the heater is faulty.
Check the wiring and connections at both heater and power module
Check the low ambient heater resistance. If not within limits replace.
As for the fan, 1. Disconnect the refrigerator from the power supply. 2. Remove all PC shelving. 3. Remove the duct grill in the PC. 4. Remove the PC duct cover and polystyrene insulation. 5. Using 2 fingers, withdraw the fan motor upwards. It is mounted horizontally in the divider partition. 6. With the motor out, this will expose a small multi plug and socket connection to the fan motor and wiring harness. Unplug. 7. To refit back together, fit the wiring harness multi plug first into the pocket of the divider partition. 8. Using your 2 fingers, slip the motor back into the divider partition to fit horizontally. NOTE: The back of the fan motor faces upwards. 9. Refit the duct covers and test.
