Additional Cross Ref., Compatibility & Installation
ATTENTION: Most of these hot tub systems have 2 Jet Pumps, an Ozonator and a single speed air blower and this alternate replacement circuit board fuly supports.

However, a few systems have a multiple speed air blower:
Keep in mind, an air blower is not a jet pump.
If the system has a multi-speed air blower, it will now operate on one speed.

There is no change for a single speed air blower.

ATTENTION: systems with 3 or more pumps are not supported.
If the hot tub system has more than 2 pumps, please contact us for another replacement option.
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.
