Hello! Sorry for the lengthy description that follows. Suddenly my 2 year old heater says: Fault Fuse link/field. It will not heat. The red heat light will not go on for either the pool or the spa. Last year this happened and I changed the fusible link and it worked fine after that. I tried that again first and it didn't work. I then followed the trouble shooting guide/flow chart with my volt meter. A,B,1,2, & 3 all were fine. (power supply & Transformer) Then it took me to test point 4 & 5 (water pressure switch). There were proper volts there. Next were points 6 & 7 (lopress fuse link). 6 had no volts (orange wire) but 7 did (blue wire). Next were 8 & 9 (highpressure limit). Neither had volts. I replaced both high limit switches completely. This did not help. A side issue was BOTH switches were in the outbound flow side. The instructions said to place the 108* red dot switch in the inlet side, so I moved it there. I then installed the 126* switch in the outlet side in the tube furthest from the heater, out of the two possible tubes to screw it into. At points 10 & 11 (ignition control) I got no volts. When I unplug one of the red power wires in to the left side of the ignition control and plug it back in, the red diagnostic light flashes once. When I test on the right side an open spot for a connector to plug into, I do get voltage, but quite low. I did NOT get volts at test point C (coming from the ignition control), but I DID get volts from D (coming from the power supply). SO I'm thinking it may be the ignition control, the power interface board (universal controller power interface), or maybe both? It seems like too many points on the power board have issues:6,8,9,10 & 11 (on the ignition control but connected to the power board). I'm handy and can replace either easily, but I don't want to buy both if 1 is not needed, and I don't want to call a pool guy because they're $180 to show up, they'll upcharge the part by 100%, and then charge another $180 (possibly) to install the new part once they get it. Any one have any idea to help? I'd appreciate it from those in the know on here! Thanks! Ron
