Hey everyone, New member here. I am having a issue with my heater. The unit is about 3 years old. It will fire up and get up to 88 degrees and then turn off and will try to cycle on and off. The AFS light will flash on and off but not consistently but no service heater light. I have recently replaced the thermal regulator as well. I do notice that the temp on the heater 104 does not match the easy touch controller as its warming up. Pulled the cover and checked all the wires and connections everything looks good. Need some help!
