Glasshopper77 Posted September 27, 2021 Report Share Posted September 27, 2021 Hi all, I had a board burn up on me with a loose heater wire. I contacted the guy who sold me the tub and he gave me an extra board he had laying around. My question is: Old board pump 1 and 2 are labeled as 15FLA New board pump 1 and 2 are labeled as 14FLA MAX If I install this new board will my pumps trip the breaker or worse burn up this board? Or is that 1 amp difference not a concern? If it matters I have Dynasty Spa with a Spa Builders Gecko board (old one) New one is a Gecko S Class Thanks!!

CanadianSpaTech Posted September 27, 2021 Report Share Posted September 27, 2021 What is the pump high speed amp draw? Should be white sticker on the pumps Quote Link to comment Share on other sites More sharing options...
Glasshopper77 Posted September 28, 2021 Author Report Share Posted September 28, 2021 Pump is SF. Amps 15.0 No listing for high or low speed amps, just the 15.0 Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted September 28, 2021 Report Share Posted September 28, 2021 Labeled where? If the relays on the board are rated for 15 or 20 amps (typical) then you will be fine. Control system amperage ratings are about circuit breaker size and what can run all at once. The individual components are standard ratings, usually 15, 20, or 30 amp. 1 Quote Link to comment Share on other sites More sharing options...
Glasshopper77 Posted September 28, 2021 Author Report Share Posted September 28, 2021 Thanks for the responses! Both pump relays on the board are labeled 10a/30a My circuit breaker size is 50a My main concern is the control box says 14amp max as you can see in the picture. (The old control box is labeled 15a). Both pumps are 15a seen in the picture. 1 Quote Link to comment Share on other sites More sharing options...
cranbiz Posted September 28, 2021 Report Share Posted September 28, 2021 FLA is Full Load Amp draw. In reality, that's an ideal, unrealistic number in a Spa. SF amps is Service Factor Amps, which is the Amp draw at full service factor (pretty much the same as FLA). Honestly, it will not be an issue. 2 Quote Link to comment Share on other sites More sharing options...
