During the middle of the first cold night the furnace stopped working while we were asleep. We could not get it to start up again though we played with the on/off switch and the temperature control switch on the thermostat. In the morning we got it working again for a while by sliding the temperature control back and forth. Then after a while it stopped working again. I noticed that if I moved the temperature control switch below room temperature and then slowly moved it to the current room temperature I would hear the slight click at the thermostat and a louder click at the furnace but the fan would not come on. Once I got the furnace fan to come on I would get ignition. So the intermittent problem is that the furnace fan will sometimes not come on. We were hooked up to shore power at the time. It would seem that the colder it was outside, the more prone it was not to work. I am now at home and the outside temperatures are way up again. The furnace now works flawlessly now that we don't need it.
