The door micro-switch does kill power to the furnace. We had a similar
problem a couple years back (mid-winter) and the company doing the
service (not anymore) took a week (yes a week) to figure it out. My
wife and I had to go down around the clock and manually restart from
the circut board. Turns out the service company said they had checked
the gas valve which it later turned out they hadn't, and the valve was
the culprit. Our lockout codes could be "overwritten" (manually) only
for a short period of time, hence the constant restarting..........Doc

Yeah. That's why I need the board to hold a code. The problem has
occurred 3 times out of probably 100 ignition cycles now. The tech who
replaced our board 3 years ago told me not to call for service until I get
a code to tell them. They could have us solve the problem by a simple
phone call.
