Question about Heating & Cooling

1 Answer

Nortron electric furnace series

Heat will not turn off when set point is reached. Even if you select heat off with the thermostat it will still blow heat. I'm not sure if I turn the fan off if heat stays on I'm afraid to do that. There must be a relay sticking I have changed the thermostat to a newer model and have had the same problem reoccure.

Sounds like a stuck sequencer. Verify there is not 24 Volt control voltage to sequencer coil, then replace sequencer.

SOURCE: Nordyne electric furnace heats up but fan won't

If the fan runs in the ON setting then you have a bad fan relay for the heat mode.
Did you install the t-stat before or after the problem?
If after, you have a bad fan relay.

SOURCE: Bryant-Carrier Furnace Fan Stays On

Hi, you have replaced the stat several times, and adjusted the anticipator so its not the stat.This is a split gas/elect unit, and working on these for many years and looking at some of the solutions given, they are right.You need to be looking at the Furnace fan control.Units of that age they do tend to stick open and run constantly.I doubt its the fan relay, maybe if you were in the cooling mode.Fan controls are not that expensive. You probably have a Honeywell 7" to 11" Probe, with the auto/manual button, with a temp dial to set you're on off temps. I would inspect the heat exchanger for any signs of cracks or bulging being its that old. If you find any, you are looking at carbon monoxided and should be thinking about an upgrade soon.Also flame roll out.I am thinking of you're safety is all.If you do have this type of fan control, there is a tab that has to be cut before you install for 24v. control.It comes set for 120v. and will burn out all of your 24v. componants.Those old Bryants will run for years. Good Luck!

Honeywell thermostat blows cold air on heat


Thermostats don't actually blow anything, the heating system might though. Check the breakers for your heat system, then call a heating specialist. They're really not that expensive.

Model sf35f furnace wont quit heating after reaching thermostat setting


Sounds like the heat anticipator in your thermostat is either bad or out of adjustment. Turn of the furnace power. Remove the thermostat wires from the thermostat. Turn the power back on. Connect the white and red wires together. The furnace should start up. Let it run a couple of minutes. Then disconnect the wires. The burners should shut off immediately. The blower will continue to run for 60 to 360 seconds then shut off. If this happens replace your thermostat. If the burners continue to burn, then your problem is either the furnace or the thermostat wires.

Atwood 38591 Excalibur xt 1522 LP two stage furnace. Operates on high fan only


Hi Dave. I'm Roger. Its normal for a furnace to shut down completely when the set point on the thermostat is reached. The first and second stages are used when the temp. gets close to set point. The heat output drops to its low stage at around 3 degrees before set point. Check your owners manual for specifics on the fan though.

Furnace blowers continues to run after reaching temp


It actually sounds like you may have answered the question yourself. If the mercury isn't breaking contact, then obviously it's still calling for more heat. This is a common problem with the old mercury thermostats and are usually replaced with digital ones that are way more accurate. The are fairly cheap at Wal-Mart and such, and replacing one is basically all color coded.

My electric furnace/heat pump runs even when the therm is off.


electric furnaces turn on the heat in stages so you dont get a major surge. the fan and the "first stage of heat" are on the same switch. that switch is stuck closed, so that it always has power going thru it. it needs to be replaced

My air handler comes on ,not the outside unit when my thermostat is in the off position even if i turn the thermostat down to 50 and have it turned off the air handler comes on for about 5 to 10 minutes...


If you have a standard thermostat the fan switch is for the air handler only. It completely over rides the thermostat for most settings. Now lets see this is what I'd expect:
fan switch on Indoor fan runs all time
Fan switch auto Indoor fan only runs when thermostat is set to cool or heat and the thermostat is turned up above room temp for heat or below room temp for cooling. In both of these modes the furnace blower comes on and stays on til the room temperature is satisfied. The outdoor unit only comes on for AC the out door unit will not come on for heat or the "on" setting on the thermostat. See exception 1 & 2 below...

Exception 1- (in a heat pump the out door unit runs in both heat and cool mode unless it has emergency heat turned on then it will not come on outside in the heat mode, and depending on the type of heat pump and furnace or air handler it is). A heat pump thermostat usually has "backup heat" and an "emergency heat" setting switch on the thermostat.
Exception 2 - On some thermostats they are made to cycle on the heat if the temperature reaches a preset temp (around 50'f usually but definitely by 40'f). This mode prevents freezing when if instance the homeowner is away or while the home is under construction. In this mode the fan inside can run but the heat usually comes on with it.
Exception3 - On some electric furnaces the heating strips may be individually controlled and thus not all come on at one time. This may give the feel of no heat especially if the room is cold.

Now there may be other exceptions but Ive tried to give you a heads up on some of the most common ones.
If you need more help please post more specifics about your unit/system as to for sure what switches are set to what setting and what is happening with each. My first though was that maybe your system is OK and you needed to know if the thermostat was working properly.

If this helpd you understand your problem would you please give me as hifgh a mark as you can. Thnaks for using fixya and good luck.
