Step 1
1
Check the power source for correct power.
Step 2
2
Check for 120Vac supplied to Main PCB. 
Step 3
3
If 120Vac is present at Main PCB test for 12Vdc to Display PCB.
Step 4
Step
Check for blinking error codes on the Main PCB
Step 5
Step
On some BLDC Compressor models it is necessary to make sure the OLP for the compressor is not open.

**NOTICE**

Wiring Colors, Connectors, and Pins will vary by model/product code. Always be sure to download and use the service manual for your specific model.

Step 1

Check the power source for correct power.

Step 2

Verify you have power at the Main PCB

Step 3

Verify you have power at the Display PCB

Step 4

Check the Main PCB for an 8 Flash Code.

If you have 120Vac at the Main PCB, see if you have an 8 flash Code on the Main PCB.

If you have an 8 Flash code, there could be a DC component  that has failed, visually check for noticeable defects.

If you have no defects you will need to start unplugging components from the Main PCB to isolate what component is the issue.

Step 5

Check the OLP for the Compressor.

If you have a BLDC compressor  it will likely have an OLP that will kill power to the unit if it is open, check this component.
