Hi!
Hope someone can answer this one.
I'm working on an old American standard, Empire boiler, with detroit controls. The relay would buzz when the thermostat was calling for heat. After doing some trouble-shooting, I replaced the relay. That worked for a couple of days, and then it started again. I had eliminated the thermostat before and it still buzzed. The transformer gives the correct 24.6 volts. So I am lost.
Anyone been in this situation before???
Thanks in advance. :)
