Error Code 83

Compressor drawing too much electrical current

Also displayed as: 83C

What This Means

Compressor winding short circuit; Compressor piston or rotor mechanically stuck; Inverter gate drive signal distorted or weak; Inverter PCB soldering defect or short circuit; Compressor current sensor defective

First Thing to Check

Parts Involved

How to Fix

1. 1

   1. Check compressor power connectors are properly seated

2. 2

   2. Inspect Inverter PCB soldering for bridges or damage

3. 3

   3. Check if compressor makes grinding or unusual noises

4. 4

   4. Verify DC 15V from SMPS is at least 13.5V

5. 5

   5. Use oscilloscope to check gate drive waveform to compressor

6. 6

   6. If waveform is distorted, replace Inverter PCB

7. 7

   7. If waveform is normal but current still abnormal, compressor may be shorted internally
