    Burner limit circuit open on a quatro consolidated furnace model MBA 100 NH3R, HELP?
    I have a burner limit circuit open code on my quatro by consolidated industries furnace model number MBA 100 NH3R. I have tested the burner limit switches and the primary limit switch. All 3 seem to be working. The condensate line was clogged over the summer from the air conditioner, which caused some water to run into the control side. That was all cleaned up and the air conditioner worked fine the rest of the summer. The furnace worked fine earlier this year. Absolutely no gas smell or flame or anything resembling heat. Has happened at all. Any help out there/
