I saw your post on boileroom.com. I don't work on furnaces or boilers. I'm an electronic
tech and work on just about everything else. I had a problem on my furnace a year ago,
it was intermittent. It uses the same module. I usually fix my own, but got frustrated and
had to call a service guy. They sent a person one day, couldn't find the problem. Sent
another the next day, thought it was a bad module, but didn't have a replacement.

I took the unit apart and found bad solder connections. Once I drilled out the two brass grommets,
I got the circuit board out. There is a nylon connector with two round pins. Where the pins
soldered into the circuit board, there was a cold solder joint. Re-soldering the pin solved
the problem.

My system went out again, I suspected the same. Found another bad solder connection, this time
on the other pin. Put it back together, still didn't work. This time, found a crack in the surface
ignitor element. Purchased a new element, heats up this time, but doesn't turn the gas on.
A friend in the business says it has to draw 3.2 amps in order to turn the gas on. I measure a
little over .4 amps although the filament seems quite bright. Either I have a bad controller yet,
or they sold me the wrong element.

If you haven't solved your problem yet, check the solder connections. Hope this helps. I still
need help, no heat tonight.
