Suggest you get some one to look at it or phone someone to find out

pro or at least some one with more experience take a look for you it
is gas after all. Strongly look at a new furnace if you can.


Just because you are ignorant and insecure doesn't mean that everyone
else is. If you don't have anything useful to suggest the than
calling a tradesman I suggest you keep your non advice to yourself.

Tony Hwang did remind me of a simple voltage test. Its there at 28
Vac. Thanks Tony. I don't do this often enough to have missed a
simple test llike that. But it was midnight, the light was poor and I
was tired. My next step is to take out the current thermocouple and
get a match. Its a $8 item and gets me out of the house. If it
doesn't fix the problem I leave it there anyway as a new one saves me
a future failure. Then I'll troubleshoot something else. The kind of
repairs require only a module change, no fancy parts repairs. That's
how things are done these days be it a module or a whole PCB for even
the most complex equipment. I have more more than 20 years of fixing
oilfield and industrial equipment.

Calling in one of your fellow tradesmen will easily set me back more
than $100 plus the aggravation of hearing him cry death and
destruction if I don't get him to replace the whole furnace
immediately. I do my own maintenance and my furnace looks as new as
the day it was installed. I had the heat exchanger tubes inspected by
the gas company two years ago and there is a lot of life left in them.
I asked and he showed me what to look for. When there comes a day for
them to be replaced I'll do it myself and I can do a better job than
many a tradesman.
