- Check for door seal.
* Evaporator ice up.
- Check defrost element, check continuity.
- Check door seal / door left open.
* No refrigeration.
- Does compressor run? If no, check power
supplies. If yes, check refrigeration system.
If running, check for live frost/fully flooded
evaporator. If not, check for leak.

- Check for fault code (refer to Sections 10.1.1
- Is there a 12Volt supply, PC light working?
- If yes, check fan connection(s) at fan end, also
at power/control module end of the harness.
- If no, check for power/control module failure.

cold.
* FC sensor location.
- Check set temperature.
Sensor clipped and located in correct
position?
* Faulty sensor.
- Check calibration of sensor ice point using
interface binary (refer to Sections 10.1.5 or
10.2.3) or refer to thermistor resistance table
(refer to Section 4.22).
* PC fan not going.
- Check for fault code (refer to Sections 10.1.1
- Check for mechanical obstruction.
- Check polarity.
- Check for broken wires.
- Replace fan.
FC TOO WARM
Bottom warm top frozen.
* Iced up evaporator.
- Check defrost element is working, replace if
faulty.
- Check doors are sealing or have they been left
