Question about Heating & Cooling

1 Answer

Turned on the furnace last evening to warm things up. When reaching the auto, shut off temperature, the fire/heat shut off OK..but not the fan. Had to shut the power off in order to shut off the fan. What might I do to fix this problem? Is there a reset button (I didnot see one)? Thanks for any help!

Turn the syestem to off-no heat or cool and the fan to auto, turn the power back on, if the fan comes on you probably have a bad fan limit switch.

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.

You have a dirty or bad heat sensor. When you remove the front panel on you furnace you will see a probe that is 2 or 3 inches long that is in the flame when the furnace fires up. If it doesn't detect a certain temperature within the first 30 or 40 seconds it shuts down the furnace. You can either clean the probe off with sandpaper, or purchase a new one. They aren't very expensive and are easy to replace. In my experience it is usually a build up of carbon on the sensor and a good cleaning with sandpaper and alcohol usually takes care of the problem.

I installed an RTH2300 this winter to replace an old mercury thermostat. It worked fine for the heating season. I turned it to Cool for the first time today and my AC and furnace blower will not turn...


Maybe turn selector switch to off.see if every thing shuts off.if yes. turn FAN selector switch from (auto) to (on) mode.does the outside unit come on or does just the furnace blower only run ? the inside fan should be the ONLY thing on.if not, reverse the (G) & (Y) wires inside the new thermo.

Fan runs long after room reaches desired temp. heat goes off and fan continues to blow cold air, have a protech 520 thermostat


Is your 'Heater' you are talking about-- A furnace-- with a burner and a blower?

Either way-- We need to adjust a control that determines WHEN THE FAN RUNS--

Most furnaces have a section where the heated air collects, and there has to be a sensor in that chamber, that senses when that air is warm enough to circulate around--- and when the burner shuts off, the air in that area cools down, and the sensor should shut off the fan-

Can you find the Heated air area?-- and can you find a temperature control in that area?-- Can you adjust the control, so that it shuts off the fan when the air temp drops to 100- to 120 degrees F...

Tell us more about the type of furnace/heater we are workig with, so I can better help you-

Furnace will not shut off after the setting is reached. have changed thermostat. Temperature reading goes down on thermostat, furnace still runs. Model : Goodman furnace,gmh95/gch9


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.

My furnace heats the house well, but during the cool down it actually blows cold air dropping the temperature causing the furnace to re-ignite. How do I adjust? Goodman - GMS9/GCS9


Depending on the age of the furnace you may be able to adjust the cool down. On some furnaces there is a silver box usually made by honeywell. This is your fan limit control. If you take the cover off you will see a dial with different temperature settings with 3 pins in a grove. The first one is fan on with temperature rise this turns the blower on when the furnace starts and warms up. The second is the fan off after furnace shuts down, this would be the one you want to adjust to a higher temperature to keep the blower from blowing cold air. The last pin is the high limit if the furnace gets to this temperature it will shut the furnace off but keep the blower running. Make sure that the thermostat fan option is set to auto and not on.

Heater won't heat very long


there isnt a pilot if it has jets , it has a Hot surface ignitor. you should see a glow and then the jets light , if its running for a few min it may be overheating, have you changed the filter recently? you should also have a flash code you can locate when the furnace shut off and is no longer doin what its supposed to look thru the bottom door peep hole and watch for a series of red flashes. if you remove the cover after retrieving the flash code there will be a chart on the inside of the cover that will tell you why the furnace is shutting off. by the way the model # you gave is for the A/C coil above the furnace, not the furnace.

The furnace is blowing warm air even if the thermostat low.


The only thing that tells the unit to come on and off is the thermostat so I would definatly say it is it. When you turn the system back on, does the a/c run normally? If it does, then it's the problem with the heating side of the tstat. Also, does the fan come on when you put it to on and then turn of when you switch it back to auto? If it does, then the system is working fine, its the t-stat. Let me know if you have any more problems.

Fan cycles on and off to often the burner stays on and the fan cy


what is happening is that the heat exchanger has to get to a certain temperature before the fan comes on that way you have warm air blowing out of the grilles and when the heat excahnger gets cool it shuts off until it warms back up again.
