Honeywell zone valve v8043e1012
Zone valve was turning when I called for heat. Wasn't engaging boiler to turn on. When I rotated dial, boiler would come on and produce heat. I was thinking zone valve end switch. I replace the whole powerhead. Worked for 2 or 3 weeks fine but it seems an intermittent problem that the valve doesn't fully engage to start the boiler. When I rotate new valve it starts boiler. Does the gold part where you sweat it into the zone go bad?
