Hello, I have a Heil 7000 furnace that hasn’t been working right. Of course it is a weekend so I’d rather not call anyone to pay weekend rates. I have done some basic troubleshooting but does anyone know of a good website that has a systematic way to troubleshoot?
The induction fan comes on, flames will light, blower fan blows then blows, then after about 45 seconds the flames will go out and the blower will run for a minute or so. After the blower shuts off I can hear an electrical humm but can’t find where it is coming from. After about 5 minutes it’ll repeat the process.
There doesn’t appear to be a flame sensor that I can find on this model. The igniter is working fine, the induction blower is working fine (I did change this about about 2 weeks ago because the old one sounded like it was going to explode, so that could be related). I sucked on the pressure switch and checked for continuity and it worked, however there was a drop of water that came out when I disconnected the line from the induction fan housing. I blew the line out. Reconnected it and then the furnace ran for a couple of minutes so I wonder why that changed. After that first cycle it went back to the roughly 45 seconds of working.
I suspect something with the pressure switch but I don’t know. Is there a good troubleshooting chart somewhere to run through this?
Thanks
