Note: If the problem is not included in the above categories, please consult CPS
service center support for addition information.
A.
No power to the unit after turning ON the Main Power Switch
Possible Cause:
Power Cord not connected correctly.
Solution:
Check to make sure the Power Cord is properly plugged into the correct power source and it is properly attached to
the back of the unit (via IEC plug). Turn main power switch on.
Possible Cause:
FX134A / FX1234 / FX3030 circuit breaker tripped.
Solution:
Check the Circuit Breaker on the back of the unit to see if it is tripped. If tripped, push the switch trip mechanism to
reset. If circuit breaker continues to trip.
Possible Cause:
The AC-DC power supply failed. The main Power Switch work through the Main PCB thus if no power to the
Main PCB via the power supply, the unit will not come on.
Solution:
Check all AC-DC power supply wire connectors are firmly engaged. Check that the Main Power Switch wires are
firmly engaged. If no output power, check the input voltage (100- 240 VAC) to the AC-DC power supply. If no inlet power
check wire connections. If inlet power is measured, then check the output voltage (12VDC) of AC-DC power supply. If no
outlet power, replace AC-DC power supply.
B.
Circuit breaker trips when plugging the unit into power source
Possible Cause:
Short circuit exists
Solution:
Take an OHM meter and check L1 and L2 of the IEC inlet to the IEC ground. If continuity exists, trace back
to where the short circuit exists.
C.
Circuit breaker trips when Compressor is to be energized
Possible Cause:
Extension cord under size.
Solution:
Use a extension cord minimum of 14ga
Possible Cause:
Compressor flooded with liquid refrigerant or seized compressor.
Solution:
Remove the front service panel. Locate the compressor suction port.
Possible Cause:
Bad compressor start relay or capacitor or bad motor windings (shorted to ground).
Solution:
Replace compressor start components and try re-starting compressor, if circuit breaker continues to trip when
there is no pressure on the compressor, the compressor maybe seized. Replace compressor.
Solution:
Also check continuity from ground to each of the compressor terminal points. If continuity exists on any of the
terminal points to ground, the compressor motor windings have failed. Replace the compressor.
