OEM Raypak 018933F PC board kit for AVIA Model 404 heaters. Replaces temperature and ignition control board to restore safe heater operation.
The Raypak 018933F PC Board Kit is a genuine OEM replacement designed specifically for Raypak AVIA Model 404 pool and spa heaters. This kit replaces the primary temperature and ignition control board, which governs heater startup, ignition sequencing, flame monitoring, and temperature regulation. It is a critical electronic assembly required for proper heater operation and safety control.
When the PC board begins to fail, heaters may experience ignition failure, intermittent firing, lockouts, inaccurate temperature control, or complete no-start conditions. Electrical stress, heat exposure, moisture, or aging components are common causes of failure. Replacing the control board with the correct OEM kit restores proper communication between ignition components, sensors, and safety circuits.
The Raypak 018933F kit is factory-engineered to match original AVIA specifications and includes the correct ignition/temperature control board and mounting hardware required for proper installation. Using the correct OEM board ensures accurate control logic, reliable ignition performance, and long-term heater reliability. Aftermarket or incorrect boards can cause operational faults, error codes, or safety shutdowns.
This PC Board Kit is intended exclusively for AVIA Model 404 heaters and should be installed only as a direct replacement for the original board configuration.

Please be advised that certain manufacturers - including Pentair® (with their TradeGrade® products), Jandy®/Fluidra® (with their Trade Series Exclusive™ products), and Hayward® (with their Expert Line® products) - do not honor manufacturer warranties on specific product lines purchased online.
These policies are intentionally enforced by the manufacturers to prevent customers from purchasing the same products at lower prices online.
Warranty coverage for these products is generally only available when purchased in person from an authorized local dealer.
While we strive to take care of our customers by offering the lowest possible prices on brand new, genuine products, we do not provide warranty coverage ourselves, nor can we guarantee that the manufacturer will honor the warranty on products purchased from our online store.
It is the buyer’s responsibility to confirm warranty eligibility directly with the manufacturer before making a purchase.
If you are a local customer, you may be able to purchase these items in-store and obtain manufacturer warranty coverage. However, for many of our customers across the country, paying significantly more locally just to access a manufacturer warranty often doesn’t make financial sense, especially when some local suppliers charge considerably higher prices.
By completing your purchase, you acknowledge and agree that we are not responsible for warranty support or claims denied by the manufacturer due to their online sales restrictions.
