What can cause the GFCI to keep tripping?
A properly functioning Ground Fault Circuit Interrupter (GFCI) activates when it senses even a very small voltage leak or short to ground. They are designed to react very quickly. The cause can be many things. To isolate the culprit, shut-off the power source, then disconnect the system’s major components including: blower, ozonator, pumps, heater, etc. Power on. If it now trips, your problem is isolated to the wiring or circuit board. If the GFCI does not trip, plug these things back in one at a time until the GFCI trips again. (Make sure power is off whenever connecting or disconnecting components). When it trips, you’ve located the culprit. If it is not one of these, check for bad wire connections, missing or burnt insulation or chafes, and loose screws or corrosion on terminals. If that is not the problem, sometimes a heater element that is going bad will cause the GFCI to trip. Another cause may be a defective GFCI unit itself. They do not last forever, and especially in damp loca
