Jandy Products PCB7588C LT Heater Control Repair Service

Professional diagnostic and board-level repair service for this Jandy Products PCB7588C LT Heater Control.

Jandy PCB7588C LT Heater Control is the main logic board that drives the heating element and safety interlocks in a Jandy LT pool/spa heater. Common failures on this model include burned or tripped MOSFETs/relays, damaged capacitors, and shorted protection circuits; power‑supply voltage drops or intermittent contact at the board’s connector can also cause cycling or no‑heat operation. First‑check steps: verify 24 V DC input to the board, inspect for visible burn marks or cracked components, and test relay contacts with a multimeter for continuity. If those are clean, review any error codes displayed on the heater’s panel and confirm that the water‑flow sensor is functioning and not obstructed. Post Comment
