First Thing to Check

Parts Involved

How to Fix

1. 1

   1. Check input voltage at power cord — should be approximately 115V AC

2. 2

   2. If voltage is normal, check inverter DC 15V output — must be at least 13.5V

3. 3

   3. Check solder joints on Inverter PCB

4. 4

   4. Listen for compressor mechanical sounds — grinding indicates internal damage

5. 5

   5. Check compressor power connectors are seated properly

6. 6

   6. If all power and inverter checks are normal, compressor is mechanically failed
