My 12 yr. od heat and air currier 8000 weather maker is acting up. The main blower(lower)
Will come on, then the top little one, the ignition gets red hot but then it will shut down and restart. Some times the propane will just ignite then shut down again. I found that if I pulled one way or the other on the upper wires, of the panel where all the wires join,(control panel) it will work fine. I haven't 180ed the panel to check out the other side yet.
Short maybe?
Thanks, tim

I get a code #31

Check for

Also check for blocked fresh air and flues, birds nest, wasp nests, plugged pressure switch vacuum ports.
