018857F Raypak® AVIA PC Board Kit For Model 264 Heaters. Restores Ignition And Temperature Control For Reliable Starts, Stable Operation, And Built-In Safety
The 018857F Raypak® AVIA PC Board Kit is the correct replacement control board kit for AVIA Model 264 pool and spa heaters. This kit is designed to replace the heater’s PC board responsible for managing ignition and temperature control functions, helping restore normal startup sequence, stable burner operation, and consistent water temperature regulation.
When the main control/ignition board begins to fail, AVIA heaters may experience intermittent operation or complete no-start conditions. Common symptoms can include ignition failure or repeated retries, burner short-cycling, unexpected shutdowns, erratic temperature behavior, lockout conditions, and recurring service faults related to the ignition and control system. Replacing the board with the proper kit—018857F—returns the heater’s control platform to correct operation and ensures proper communication with the heater’s sensors and wiring harnesses.
This is a complete PC Board Kit (not just a bare board). In addition to the replacement control board, it includes the required mounting spacers used to properly secure and isolate the board in the heater’s control compartment. For AVIA heaters, the 018857F kit is specifically for Model 264 (it is not the same kit used on Model 404).
