jimpoleshuk Posted August 19, 2018 Report Share Posted August 19, 2018 I have 110v plug and play. 12 Ohms across element.(disconnected from controller) 0 Volts across element when calling for heat 120v from on each leg to neutral when calling for heat. 0.1 amp, essentially zero with amp clamp over each lead going to heater when calling for heat. Any ideas? Quote Link to comment Share on other sites More sharing options...
jimpoleshuk Posted August 19, 2018 Author Report Share Posted August 19, 2018 The heater relay is not closing. When i manually engage it, I get 10 amps to the heater. Its not getting the 16volts to actuate Pressure switch is set right. Another relay clicks on when heat is called for. Quote Link to comment Share on other sites More sharing options...
mrwrick Posted August 19, 2018 Report Share Posted August 19, 2018 I have a 110 volt spa. My heater system showed similar result oin tests. I had a bad relay. There were 2, I replaced one, but it was the wrong one. Once i replaced the correct heater relay all works well for several years now.Good luck, Use this form and the manufacturer contacts. They all helped me. Quote Link to comment Share on other sites More sharing options...
