How to Fix / Troubleshooting
Safety: Repeated breaker tripping indicates a potentially dangerous fault. Turn off the breaker and do not reset repeatedly. Only a qualified person should troubleshoot.
- Visual inspection: Look for burned wires, melted insulation, or scorch marks inside the electrical compartment and around the blower and transformer.
- Isolate components: Disconnect suspect loads (blower, transformer) one at a time and test if the breaker still trips when power is applied. This should only be done by someone comfortable with electrical testing.
- Check breaker rating: Confirm that the breaker size matches Zodiac installation requirements for the heater's amperage.
- Replace failed components: Replace any shorted blower motor, transformer, or damaged wiring with Zodiac-approved parts.
- Professional service: Due to shock and fire risk, have a licensed electrician or pool heater technician complete this repair.
