Additional Cross Ref., Compatibility & Installation
This alternate circuit board replacement package includes a new circuit board and a new compatible topside keypad with a 10 foot cord!
Tip: The old (original) topside keypad is outdated, not compatible and replaced with the new topside keypad in this package.

If you want this same package deal with a shorter topside cord at a lower price, please scroll down to Related Products and find the other alternate replacement shown.

ATTENTION: Some of these hot tub systems have an optional auxiliary topside keypad that is also not compatible with this alternate replacement circuit board.
If you have an optional auxiliary topside keypad, please call us with its part number (before placing this order) for inquiries on replacement availability.
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.
