I have recently purchased a 1973 boler
with a wagonmaster furnace
.I am familiar with how a gravity propane furnace
works. the furnace
has not worked for 10 years or so. The problem is the pilot light
not staying lit when releasing the control.
After trying new thermocouples and heating them with a butane torch even, I am most certainly getting the 35mv. that is supposed to be enough voltage to energize the pilot light
valve electromagnet that in turn keeps the pilot light
valve open, when the push in control is released.
I decided to remove this electromagnet and bench test it. I found that a 1.5vAA battery
would most certainly turn it into an electromagnet, but the paltry 35mv was not up the the job. Has anybody out there gone this deep before, and can you provide me with some insight? The windings on the electromagnet do not appear to be damaged or burnt. If there are any retired or current rv furnace mechanics out there, perhaps you have heard of this and it may be a common problem. thanks
