Issue: No Cool/No Compressor Operation

Troubleshooting: First confirm the fan motors are running.

Note: If any of the fans are running, the Main PCB is calling for cooling and the Inverter PCB should be receiving a sig-

nal to run the compressor.

To begin troubleshooting, follow these steps:

1. Access the inverter PCB located directly above the Main PCB on back of the unit, and then check the status of

the Red LED.

2. If there is no LED operation, check the fuse. If the fuse is good and 120VAC is present between the Red and

Grey wires, replace the Main PCB. See the diagram below.

3. If the LED is on or flashing, the main PCB is functioning normally and you can do all the remaining test proce-

dures from the Inverter PCB. Identify the number of LED flashes to determine the error code.

Regardless of the number of flashes, follow these test steps:

1. Using the diagram below, check the resistance of the compressor windings. The resistance should be approxi-

mately 10 Ohms. Measure the resistance between: Blue – Purple, Blue – Black, and Purple – Black.

2. Check the Over Load Protect (OLP). It should be closed.

3. There should be 120VAC present between the Red – Grey wires.

If the LED flashes 1, 2, or 3 times, and all tests pass, replace the Inverter PCB.

If the LED flashes 4, 5, or 6 times, and all tests pass, suspect a failed compressor. Replace the Inverter PCB and com-

pressor.
