Additional Cross Ref., Compatibility & Installation

This package deal includes an alternate replacement circuit board and a compatible topside control panel.
The old (original) topside control panel is outdated and not compatible.

ATTENTION: Some of these hot tub systems have an optional auxiliary topside control panel that is also outdated and not compatible with this alternate replacement circuit board.
If you have an optional auxiliary topside control panel, please contact us to inquire if a compatible one is available.

This alternate replacement only supports a single speed air blower.
Tip: an air blower is not a jet pump.
Jet pumps are fully supported.
If you have an air blower with more than one speed, you will need to choose a speed and disconnect the wires of the other speeds.

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.
