furnace now working
We have an '86 Excella 500, 32 foot we bought last fall. The furnace started once for us before the very cold temps hit so we couldn't do any repairs we wanted to get at thru the winter.
We got the furnace working--finally. I decided to replace the regulator and when I took the original one off, a lot of thick oil like liquid poured out. I guess the oil kept the gas from flowing , in volume, to the furnace but allowed the gas to the stove. I don't know where this oil came. All I know is--now the furnace is working great.
I just wish I had thought of this earlier.
So, if your furnace is not working but the burners will fire--check the regulator-- this may need to be replaced.
I hope this helps.
