Issue:
Compressor is starting fully loaded
Resolution:
- Check amp draw on startup to see if the compressor is truly starting at 100% RLA
- Check the chart in the notes section below to see how the compressor load should ramp up
- Note whether the female load stepper pulls in or not, and how fast the compressor loads up to full load.
- Compressor full load should not occur quicker that 1-2 minutes after compressor start.
- Next, use a gauge set hose to unload the male piston pressure back to compressor suction via a schrader near the male loader solenoid valves.
- If the male piston is stuck, then it can be replaced. Use RTAA-SVB-12A-EN for instructions.
- If it is the female unloader that is stuck, this cannot be easily repaired. The compressor will have to be replaced.
