Possible Causes

Moisture in electrical compartment, Damaged insulation on wiring, Failing compressor or fan motor with ground fault, Incorrect neutral/ground bonding

How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping GFCI. Turn off power and investigate the cause.

  • Inspect for moisture: Open the electrical compartment and look for water, condensation, or corrosion. Dry thoroughly and correct any leaks.
  • Check wiring insulation: Look for nicks or cuts in wires that could contact the cabinet or ground.
  • Isolate components: A qualified technician can disconnect the compressor and fan motor one at a time to identify which component is causing the ground fault.
  • Correct bonding/grounding: Ensure the Raypak unit is bonded to the pool bonding grid and grounded per code. Incorrect neutral/ground connections in the panel can also cause nuisance trips.
