2.2 REFRIGERATOR TOO WARM (Warmer than 8
0
C)
SYMPTOMS OF THE FAULT
1.The refrigerator compartment is too warm.
2.the compressor MAY not be running or running
Only very occasionally
Hoe to confirm this fault
1. Check the evaporator is adequately defrosted. If it is not this may be the problem.
Defrost the refrigerator.
2. Check that the “Do Not Freeze Ice Packs” or “Refrigerator Disconnected” indicator
lights are not lit. If they are lit the problem is not the thermostat, so proceed to the
next step in the faultfinding chart.
3. Check the thermostat wires are tightly connected to terminals T and C of the
compressor controller. If tightening the connection causes the compressor to run the
fault has been repaired.
4. Check the thermostat wires are tightly connected to the thermostat unit
(Mechanical type only). If tightening the connection causes the compressor to run
the fault has been repaired.
5. Check the wires from the thermostat unit to the compressor controller for signs of
damage. If damage is apparent replace the wire.
6.Adjust the thermostat to its coldest position.
7.If the compressor now runs the thermostat setting was incorrect. Adjust the
thermostat to obtain 2
0
C to 4
0
C in the bottom of the refrigerator compartment as
explained on page 83.
8. If the compressor still does not run connect a wire across the 2 terminals of the
thermostat.
