    Bryant furnace 310AAV042090ACJA not warming.
    I have a Bryant furnace, model 310AAV042090ACJA, that's throwing an error # 33 - limit circuit fault. I believe the limit switch is bad. Am I correct in my assumption? Or is it something else?

    The whole house is not getting warm. The furnace will run for a bit (including the blower motor) and then shuts off. It never reaches complete temperature in the house. It only gets to around 57 F (when it's 20 something outside) and doesn't get any warmer.

    Is it the limit switch?

    It turned out to be clogged A/C coils. A thorough cleaning resolved the issue.

Oil Furnace not warming house [ 12 Answers ]

Our oil furnace doesn't give us much heat in our bedrooms which are on the end of our home. We removed a wall in our kitchen a few years ago and it's very uncomfortable now. Our Home is 1354 Sq. Ft. and we think it should be warmer than it is. Any suggestions?
