Hidden Heater Diagnostics
Heater terminals are located on the side of the pump motor assembly, and can be tested there or at the
main control board. Remove connector J703, and look for 10 to 15 ohms across the violet to white/red wires.
If the circuit is open, replace the complete pump motor assembly. Voltage may also be checked with the
main control in the service position. With all connectors seated, place in
the circulation pump to power the heater. Check for 120 VAC at connector 703 across the violet to white/red
wires.
