Looking for some advise. The furnace stopped working in the following way. It got cold, so I turned the heat on. In looking at the furnace, there was a delay of around 7 minutes before the induction motor kicked on and the glow plug started to glow. The furnace would then ignite, but within 5 - 20 seconds, the induction sensor relay would click and the flame would go out. It would then try to re - light with the same results until I turn the furnace off. I did find that while the furnace was trying to stay on, if I unhooked the connectors to the induction sensor relay, and shorted them out, that the furnace would run for as long as I had the connection shorted. When I hooked the sensor back up, it went back to to the same on/off/on/off symptom....

My question is, what is failing. Is it a bad induction sensor, or is it possible that the induction motor is failing causing the sensor to turn off?
