GB142 Intermittent No Heat
Taco zone control shows zone one calling for heat, circ pump running, GB142 is not firing. No error codes. I switch off boiler, wait maybe 5 minutes, switch on and it fires. Had thoughts about jumping out AM10 outdoor reset. Any other ideas? Has not been service since installed almost 3 years ago. Thanks a lot for any help!
