FAULT CODES

If  a  fault  should  develop  in  the  temperature  measurement  system,  defrost  system,
temperature control variable resistor, or should the compressor fail to start, an audio
fault alarm will sound when to P.C. door is opened.  The alarm consists of a number
of beeps emitted by the beeper located in the control module.  The number of beeps
emitted indicates the fault as shown in the Fault Code Table below.

3.1 

Fault Code Table

Fault 2:

2 beeps

Reason:

Defrost sensor failed to reach +8

o

C within 30 minutes.  This has

happened  in  the  last  three  defrosts,  therefore  probably  defrost
heater failure.

Action:

Check connections at the control module and inline connectors.
Check defrost heater.  If faulty, replace.

Fault 3:

3 beeps

Reason:

The  resistance  of  both  the  temperature  sensors  is  outside  the
normal range (> 45K Ohms).

Primary Action:

Check the 4 way connector at the control module.

Secondary Action:

Check sensor resistance.
Re-terminate the 4 way connector.

Tertiary Action:

Replace the control module.

Fault 4: 4 beeps

Reason:

The  resistance  of  both  the  temperature  sensors  is  outside  the
normal range (< 660 Ohms).

Primary Action:

Check the 4-way connector at the control module.

Secondary Action:

Check sensor resistance.
Re-terminate the 4 way connector.

Tertiary Action:

Replace the control module.

Fault 7: 7 beeps

Reason:

The resistance of the defrost sensor is outside the normal range
(> 45K Ohms).

Primary Action:

Check sensor resistance.
Check the sensor connection at the control module.

Secondary Action:

Replace the sensor.

Fault 8: 8 beeps

Reason:

The resistance of the defrost sensor is outside the normal range
(< 660 Ohms).

Primary Action:

Check sensor resistance.
Check the sensor connection at the control module.

Secondary Action:

Replace the sensor.
