Unitherm Governor Plug blew out today, I was not around when in occurred. I tested the Unitherm Governor (UG) in a pan of hot water, it cycled open and appeared to function properly. What else could cause the plug to blow?
I am debating purchasing a complete header kit, but what to make sure I am addressing the root cause.
Of note, I replaced the heat exchanger this summer, my old one had a small leak that corroded the lower studs and heater frame. I found an old unit in good shape to fix the frame and bought a new Hx. Everything appeared to work properly with no leaks up to this point.
