This could be a couple of things, first is the fan limit switch. Make sure your fan limit is set at the correct settings, there is a fan on setting and a flame shut off setting located on the front of air handler inside the front cover. Usaully set at 140 fan on 200 gas shut off. You do not say what unit you have so this could be a pc board or module. Second this could be the blower it's self over heating and shutting down, feel if motor is gettig hot. This could be a run cap. or motor it's self. But it is more than likely the limit switch.

Have a miller furnace. and when i light the pilot, and turn on the furnace. the combustion chamber comes on. it blows out the pilot whats the issue please help no heat.


if the pilot goes out before the fan comes on then your heat exchanger is plugged . if it goes out when the fan comes on then you may have a cracked heat exchanger. it also could be dirty burners with a delay. is there nd slight poping on igintion see if cross overs on the burners are dirty

Rheem 90+ NG Furnace. When furnace starts, draft inducer starts, ignitor glows and gas ignites. Burners stay lit for 10 seconds or so, then the flame reduces for a few seconds then goes out. Main blower...


Check the draft inducer air switch ( vacuum diaphragm switch) If the switch is opening when the burner starts, you might have a blockage on air piping coming into the furnace. Also prime the condensate trap on the condensate drain from the combustion fan. Also check the gas pressure, if your gas pressure is dropping, the gas pressure switch will shut it down. If it's too high the moment it comes on could raise the pressure in the furnace dropping out the combustion fan proving switch.

Can you tell me the order in which each componet of a gas furnace comes on to start the furance?


Yes there is a sequence:
0:00 Dial for fan/limit switch is at 70 deg position. Furnace is cold. I turn T-stat to 80 deg to start furnace.
1:00 Burner comes on and dial begins to move slowly up.
2:30 Dial at 140 deg and fan motor comes on. Dial never goes above 150 deg.
3:00 Burner turns off. Dial slowly moves back towards 90 deg.
4:45 Burner turns on and dial is at 110 deg.
4:50 Fan turns off with dial still at 110 deg.
5:30 Burner off. Dial at 120 deg.
6:15 Fan on. Dial at 140 deg. Burner is still off.
7:00 Burner on. Dial at 120 deg.
7:40 Burner off. Dial still at 120 deg.
8:30 Fan off with dial at 110 deg., and it quickly snaps back to the 80 deg. position.
8:30 plus, cycle continues.....

Goodman GS9 propane furnace inducer motor runs continuously


it sounds like the low temp limit switch, the one that cools the furnace down with the burner off and the thermostat open, when it cools to a point the fan stops, the other switch in burner area turns burner off/on, hope this helps

Main blower stays on, burner fan on intermitantly,


All gas furnaces have a fan control of some sort. Either a mechanical fan control where there is a temperature probe that reaches into the heat exchanger compartment thru a hole in the panel that separates the control part of the furnace(this would be the front of the furnace where all the controls are) from the heat exchanger. This type of control is either a small black plastic control about 4 inches by 2 inches and about 1 1/2 inches thick secured to the panel with 2 screws. Or it is a slightly larger silver colored control that should have a pull off cover. It may say Honeywell on it. Either way the control will need replacing.
The other type of fan control is a solid state control board. This will most likely be located in the indoor fan compartment. It should be located under a covered control box. The box with all the wires going into it. This board will also need to be replaced if your furnace uses this type of fan control. You will need to bring your furnace model and serial number to a dealer that sells your brand of furnace or go online to a parts dealer that carries parts for your furnace. Hope I was of help to you! Good luck!

Furnace pilot problem


check the pilot gas pressure, might be too weak and blowing out when the blower starts, the clicking noise is the gas valve shutting down when it detecks no pilot flame, that park is normal.

Burners come on and go out amana 80sse


Ths is an easy problen to solve. Looking close to the burners is a pilot sensor. It looks like a thin metal pin about 1" 1/2 long. Clean this with sandpaper. This will allow you furnace to stay lit.

Hope this helps,
