Last weekend my pool heater was working fine. My pool heater is a Aquacal 155 that is only three years old. This weekend I noticed that the heater was not producing any heat. The fan runs and the heater light displays "heating" I can here the relay close but no heat, no condensation and the compressor does not run. I took off the front covers and take a look at what I found. There was no moisture or condensation in the box. No insects or animals that I could find that would cause a short. The heat was so intense it melted copper wire. The two wires in the photo are going to the compressor. The source wires to the relay look fine.
Opinions are appreciated.
