9 Faulty compressor Remove the Module as above, & unplug
from the compressor. Check that ohm
readings are the same across all
terminals of the compressor.
10 Heat sink overheated Allow components to cool down before
attempting re-start.
11 Compressor too cold If compressor is below freezing
temperature, allow to warm up before
attempting re-start.
C: Compressor Attempts to Start, or Starts Then Stops Shortly After:
1 Faulty or inadequate
power supply
Monitor the supply voltage at the

attempts to ensure that it does not fall
below threshold levels. If it does, check
power supply, ground connections &
components for integrity. Check for
correct wire sizing. Charge batteries if
necessary.
2 Faulty fan or pump relay
or unauthorized
component installed
Remove connectors from F & +
terminals on Module & attempt re-start.
Maximum current draw on these
terminals is limited to 0.7 amps 12v
3 Quick Connect fittings not
made
Check that all refrigerant fittings are
connected together properly.
D: System Runs, Box Temperature Too High:
1 Thermostat setting Rotate thermostat knob clockwise to a
higher number.
2 Speed setting
