anwar Posted May 29, 2015 Report Share Posted May 29, 2015 I have a Jandy Lxi heater that will not run. I have it narrowed down to either the blower motor or the ignition control. (All of the limit switches test OK) The blower motor will not turn on. I replaced the capacitor because it tested bad. It is 220v and it appears that the ignition control powers the blower from the terminals F1 and F2. F1 is putting out 120v but F2 is putting out 3.7. Does anyone know what voltage should be at F2? Is there a prefered way to test the ignition control? Thanks for the help. Quote Link to comment Share on other sites More sharing options...
Bugman1400 Posted June 29, 2015 Report Share Posted June 29, 2015 Did you ever get your heater working? I doubt its the ignition module. There are a lot of safety checks/switches that have to be verified before the blower starts. Quote Link to comment Share on other sites More sharing options...

Bugman1400 Posted July 13, 2015 Report Share Posted July 13, 2015 Since the motor is 220V, the ignition module will have 120V on F1 (Phase 1) and 120V on F2 (Phase 2). The F1 will always have the 120V but, the F2 will only switch in the other 120V when all the safety checks have passed. I would use a jumper to figure out which safety switch is bad.
