Check if your thermostat is set on 'o fan' setting.
If it is, trey to set it on 'Auto-fan' instead.
since it seem as if the heating does go off,only the fan may be running continuously.
this is possible if the thermostat is incorrectly set or installed.
good luck.

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.

Does the furnace stays off?.
Furnace are ment to cycle on and off because of limits .If you set to 70 furnace would cycle several times before reaching that temperature.
Just make sure your filters are clean and you got proper return air flow because lack of air flow will cause furnace to shut off sooner than normal

I have an early 80's mobile home with an "intertherm gas atmospheric furnace" pilot light is lit but can't get the furnace to "fire". Seems as though the limit control is stuck open. ...


If your pilot light is lit then I would first check your thermostat. Make sure it is on heat setting and fan is on auto, turn stat up to where it should be calling for heat. If you don't get burner to light remove front cover from thermostat and see if it has a mercury switch, if it does move temperature selector up and down and see if you can see a spark in mercury switch vial. If y ou cannot see a spark remove screws that attach t-stat to base.Remove carefully and disconnect wires that go to r and w terminals on stat base. Temporarily connect these two wires together. This should make burner light if you have power to thermostat. If burner does light disconnect wires and replace thermostat. Also if you have a volt meter check across these two wires and see if you have power there. Should be around 24 volts a.c. If your thermostat has a fan on setting try that. If fan runs you know you have power to furnace The gas valve needs 24 volts to operate and inside the electric control box in furnace there is a transformer to step down 110-120 supply voltage to 24 volts. If transformer is working you should be able to hear a low buzz or humming sound. You can also check across gas valve terminals when t-stat is set for heat, you should read about 24 volts. If you have 24 volts to gas valve and it is not opening then you need to replace gas valve. The main purpose of the limit switches is to turn blower on when temperature in heat exchanger reaches fan on temp,shut off blower after burner shuts off and heat in heat exchanger reaches fan off temperature, and limit if temperature exceedes set point without blower coming on. I hope this helps you. Thanks

Gas Furnace will not start when outside temperature rises to 50F


There is a pressure switch near your draft inducer motor that needs to close when draft inducer motor is running. Verify that the switch is closing. If it is not closing, you might have a problem with either the switch itself, or there could be some sort of blockage in your flue. I would start with the switch first. This switch has to "prove" before it will allow anything else to happen. The loud click could be from your switch or your gas valve. If the switch is closing and nothing else is happening, it could be a problem with your gas valve or HSI.

Electric furnace runs but won't shut off on heat setting


I would insist that Sears either have a Senior tech come out and fix it or return it to the state it was prior to them touching. Then call some one else. Have them involve the Goodman rep in your area.

Furnace blower not working how it should


first off buy yourself a honeywell stat, in my personal opinion lux stats are garbage, I have run into so many that are bad stats !!! but as far as your fan not shuting down, sounds to me like your fan center on your circuit board is bad and will not shut down the fan when needed, you will have to replace the circuit board, as the fan center is a part of the whole of the circuit board, hope that helps

RUUD (Protech Model 500) Thermostat Single Stage Not Programable


problem is not the thermostat, thermostat is an on-off switch that happens to work on temperature. Your furnace is locking out. cycling the heat off switch resets the micro-processor in the furnace. You need to diagnose the problem in the furnace, to go further we will need the model and approximate age of the unit
