Fafco Electrical Overload or Short in Solar Pump Circuit

The solar system causes frequent trips of the electrical breaker when starting.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Solar pump motor shorted or seized, Undersized breaker for the pump load, Damaged pump cable insulation, Water intrusion into the junction box

Safety: Do not repeatedly reset a tripping breaker. Turn off power and investigate.

Inspect pump: Check the solar pump for signs of overheating, a burning smell, or a seized shaft.
Measure current draw: With a clamp meter and appropriate safety, measure pump startup current and compare it to the breaker rating.
Check wiring: Inspect the pump cable and any junction boxes for damage or moisture. Dry and repair as needed.
Replace faulty pump: If the motor is shorted or locked, replace the solar booster pump with a Fafco-specified model.
