    Blower Running but no heat is coming out
    My central heating and air unit stopped putting out warm air last night. I woke up freezing. The blower will still run but no warm air will come out. What steps do I need to take before calling a repairman?

    I had the same problem. The problem was the flame sensor. I have to clean it every year. Shut the furnace off at the switch on the furnace. Remove the flame sensor and clean it with an emery cloth. Re install it and turn the switch back on. Make sure all the covers that you remove are put back in place before you turn it back on.

    Where might this flame sensor be found? I have a carrier unit.

    You may only be able to see the back half of it which is the part with the blade on it for the electrical connection. It'll be held in with a hex head (probably) screw.

Musky odor coming from heat vents [ 1 Answers ]

We installed a humidifier to our furnace in February. Could it be causing the musky odor that we periodically get from the vents? What is funny about it is that the smell is not there 24/7 and when it is present it comes more from one or two vents only. If that makes any sense.
