WHENEVER I TURN MY HEAT UP, MY FURNACE IS ALL OF A SUDDEN RUNNING LOUD. THE FLOOR IS SHAKING, THIS DID NOT HAPPEN LAST WINTER, HOWEVER THE BLOWER DID GO OUT LAST YEAR AND IT HAD TO BE REPLACED. THE FURNACE IS ONLY 2 YEARS OLD.

Re: FURNACE RUNNING LOUD
Sounds like either the motor is off balance
or is going bad again
either way id be on the phone to the guy who did the rapair
more than likely the set screw on the sqiral cage came loose and now its vibrating

Check all wire connections for tightness. Those solenoids on the humidifiers will eventually need to be replaced. Try turning the dial all the way up to the test position if it is still clicking you may just need a new solenoid.
Hello, seems like there is no way to turn on the humidifier. There would either need to be a new transformer installed, a current sensing relay, or a sail switch to activate the humidifier when the blower motor kicks on.
If the humidifier has a 6" duct on one side, this must be open in winter you should find a handle, if there is not any label, move it so the handle is parallel to the ductwork.
If the humidifier do not have a duct on one side, it must have a fan, if you can't hear it working, probably is time to get a new humidifier, and make sure contractor check furnace heat exchanger for CO2 leaks.
Really not efficent to run a heat pump at those temperatures. Below freezing is not good for the compressor in the outside unit. The humidity in the house with the low temp. is causing the condensation on the windows to freeze. Kinda like an air conditoner does in the summer without the freezing humid air from the house goes over the cold a/c coil and the moisture condensates on the coil running down to drain pan. raising the temp. in the house and lowering the humidity should help. I would also recommend running the electric heat in low outside teperatures.
Hi John Your whole question did not show up (maybe you can re-post) . I can answer what part i understand though. If the humidifier was wired in right it will not send power to the humidifier until the furnace is on, and calling for heat. This stops the unit from working in the cooling mode in summer.Make sure your furnace filter is clean as well
The humidifier should not turn on untill the furnace blower starts. Since the fan stays on. does the solenoid valve also stay on? If they both stay on you probably have a bad humidistat. If only the blower stays on then the circuit bourd in the humidifier is defective.
I called the service company that put in my new furnace (FAmily Heating and Cooling in Detroit, very highly recommend these people)
Anyway they sent out a second service tech who determined that I would be better off having the humidifier wired to go on whenever the furnace fan was running instead of using the humidifier signal from the circuit board on the furnace. After he changed the wiring the unit runs fine. It is pretty likely that the circuit board was bad also.
