Munchkin, Blown Fuse on Circuit Board
Plenty of Munchkins in my area, but I've never had to service one with a blown fuse on the circuit board. This boiler is a 140M, made in 2002 and had a new circuit board installed 2-3 years ago. There's probably plenty of of things that could short out; gas valve, blower motor.....Can I ohm these components out to see if they are good or bad?
The owner had called me a few days ago to say that her zone valve controller had died. I haven't gone out yet. The two seem unrelated unless there was a power surge.
Often wrong, never in doubt.Click here
