I didn't time it, but it seemed to try to start for a minute, then pause for a minute and repeat. So, in the hour I thought about it, it must have tried 30 times or so. The house only cooled a few degrees and it was frigid out, so it couldn't have been too long, but lets say it cycled 40 times before I fixed it.
It is working fine and I don't want help fixing it. I just have a simple question... how long does it do that before it simply stops? Well, two simple questions... if it does in fact stop, does it ever try again?
Reason I ask... the house is 6 years old. Former owner didn't live here, but had the heat on in the winter. Seems strange that it worked fine for 5 years and failed my first year. Maybe it did fail, but no one was here to know. When it warmed up and the ice melted, it started again. They drained the water, so there would have been no damage.
It would eventually stop trying, and shut down for life, or a power outtage, or someone turning the furnace breaker off and back on. Whichever comes first.
