Adam F Posted September 12, 2017 Report Share Posted September 12, 2017 95 midel f, no heat. Circ pump flows, turn thermostat dial and I can hear it kick in, wire going to heater gets luke warm, but no heat. Tested continuity at heater and I got 10 ohms (good) so what is the problem?

mrwrick Posted September 13, 2017 Report Share Posted September 13, 2017 Check the relays for the heater. There may be 2, one for heater, one for jets or heater. Quote Link to comment Share on other sites More sharing options...
Adam F Posted September 13, 2017 Author Report Share Posted September 13, 2017 It appears to be a PITA to get at the control box, its in a tight spot and doesnt open up from the outside. Id have to remove it to check. Can I unplug the heater from the box, and use my meter to see if I'm getting 110v at the plug? Quote Link to comment Share on other sites More sharing options...
Adam F Posted September 13, 2017 Author Report Share Posted September 13, 2017 How do I test the 2 thermistors that are located on the no fault 1500 heater housing? Can I bypass them somehow to force it to heat up? Quote Link to comment Share on other sites More sharing options...
