Paul S Posted February 24, 2019 Report Share Posted February 24, 2019 I have a Limelight Flair (FLR1R3307) that had a bad topside control board. I replaced it with part #76845 but now pump 2 is not working. It was before the top board went bad. I noticed the black wire from motor 2 is not connected. Apparently it was working with only the green and white wires connected. Two questions: (1) Can I test pump 2 by plugging all three wires from pump 2 onto the pump 1 pins? (2) Does the new top board need to have the pump 2 black wire plugged in somewhere? Quote Link to comment Share on other sites More sharing options...
Paul S Posted February 24, 2019 Author Report Share Posted February 24, 2019 Problem solved. I found out why the wire was off. Quote Link to comment Share on other sites More sharing options...
Hot Spring Official Posted February 26, 2019 Report Share Posted February 26, 2019 Changing the top side should not affect the program of the main board, so it should still know it has 2 pumps. All 3 wires need to be connected for the pump to work, and you should also have an external copper bonding wire on all the pumps and heater. Please check with your local dealer if you have any questions to verify your tub is working safely and properly. Quote Link to comment Share on other sites More sharing options...
