2) PROBLEM The compressor does not work
CHECK Make sure that there is 12 VDC between the black wire of the relay [Fig. 16 ref. 2] and the red
wire of the fan speed selector [Fig. 16 ref. 8].
OPERATION Check the harness and the multi-wire connector [Fig. 16 ref. 7].
CHECK Make sure that there is 12 VDC on the fan speed selector [Fig. 16 ref. 8] between the orange and
the black wire of the relay.
OPERATION Replace fan speed selector.
CHECK Make sure there is 230 VAC between the white wire of the relay [Fig. 16 ref. 2] and the blue wire
of the feeder input terminal [Fig. 16 ref. 4].
OPERATION Replace the relay.
CHECK Make sure that when the hot/cold selector switch [Fig. 16 ref. 3] is positioned on cold, there is
230 VAC between the pink and the blue wire of the infeed terminal [Fig. 16 ref. 4].
OPERATION Replace the hot/cold selector switch.
CHECK Make sure that there is 230 VAC between the violet wire of the thermostat [Fig. 16 ref. 5] and the
blue wire of the infeed terminal [Fig. 16 ref. 4] (when the ambient temperature is below 16(C, the
thermostat will not close its contacts, so this test must be performed at an ambient temperature
over 20(C).
OPERATION Replace the thermostat
CHECK Make sure that when the hot/cold selector [Fig. 16 ref. 3] is in cold position, and after the plastic
side cover has been removed, the following are on the compressor [Fig. 16 ref. 11]: voltage at
230 VAC between the blue and the white wire; voltage at 230 VAC between the black and the
white wire; voltage at about 250 VAC between the orange and the white wire.
OPERATION Check the connector and the harness.
Replace the temperature switch on the compressor.
Replace the condenser [Fig. 16 ref. 10].
3) PROBLEM The fans do not work
CHECK Make sure that there is 12 VDC between the black wire of the relay [Fig. 16 ref. 2] and the red
wire of the fan speed selector [Fig. 16 ref. 8].
OPERATION Check the harness and the multi-wire connector [Fig. 16 ref. 7].
CHECK Make sure that there are 12 VDC between the green speed selector switch wire [Fig. 16 ref. 8]
and the black relay selector wire [Fig. 16 ref. 2].
OPERATION Replace the fan speed selector switch.
CHECK Make sure that there is 12 VDC between the black and the green wire of the evaporator ventilator
[Fig. 16 ref. 9].
OPERATION Check the harness and the multi-wire connector.
CHECK With the hot/cold selector [Fig. 16 ref. 3] on cold position, make sure there are 12 VDC between
both brown wires and the red wire of the ventilation speed selector [Fig. 16 ref. 8].
OPERATION Make sure that the contacts 2 and 3 of the hot/cold selector switch are closed, and replace them if
necessary.
CHECK Make sure that there are 12 VDC between the black and the red wire of the condenser [Fig. 16
ref. 12].
OPERATION Check the harness and the multi-wire connector.
4) PROBLEM The fan of the condenser does not work
CHECK With the hot/cold selector [Fig. 16 ref. 3] on cold position, make sure there is 12 VDC between
both brown wires and the red wire of the ventilation speed selector [Fig. 16 ref. 8].
OPERATION Make sure that the contacts 2 and 3 of the hot/cold selector switch are closed, and replace them if
necessary.
CHECK Make sure that there is 12 VDC between the black and the red wire of the condenser [Fig. 16 ref. 12].
