Additional Cross Ref., Compatibility & Installation
ATTENTION: You will LOSE the SECOND speed on Pump 2 when using this replacement circuit board.
Everything else operates the same.

If you don't want to LOSE the second speed on Pump 2 then do NOT place this order.
Instead, please give us a call for another replacement option (if available).
Tip: When replacing a hot tub circuit board, testing the heater and replacing it (if bad), is recommended before installing or applying voltage on a new circuit board.
Note: A continuity test is not a sufficient heater test. Contact us by phone for more details on testing a heater.

Tip: Burned circuit boards or burned heater relays are often due to a loose electrical connection or a bad heater or both.
If all connections are tight and if the heater is good then the heater relays are probably old and worn out.
If a burned relay was powering a pump and all electrical connections are tight then the relay is probably old and worn out or the pump might be bad or going bad or all three.
Replacing the heater and/or pump with a new one is recommended if any of those scenarios apply.

Tip: Items shown in RELATED PRODUCTS below have also been found in hot tub systems with Balboa 52252 SW100R1(x) circuit boards.
