SOURCE: ignition failure code on

Sounding like a flame proving device is failing to sense flame. Try to clean the device with some steel wool. It is located right next to the last burner looks like a thick wire. Take the steel wool and gently rub the carbon that has built up off. Should only take 4 or 5 strokes. Let me know it that did it. Ken

SOURCE: Carrier Gas Furnace and Hunter Thermostat not working

Definitely a furnace issue. The gas valve is not opening if you see no flame. I have seen the igniter glow but not send enough voltage to the circuit board to make the gas valve open. If this is the case you should replace the igniter. It is very fragile so please use care when replacing. Check all connections at the circuit board as well as the gas valve. Check your gas supply. Check to see if you get 24 volts AC to the gas valve. If no, replace the circuit board. If yes, replace the gas valve once you confirm that you have gas to it. If you get a pilot flame only, you will need to clean the burners and flame tray that spreads the flame from one burner to the next.

SOURCE: furnace ignites when thermostat calls for heat,

You don't say if the blower is coming on, no blower would cause the limit to open. By the way, the limit is internal and auto-reset, not the manual reset roll out switches on the burner assembly.

SOURCE: I have a gas furnace with electronic ignition.

Hopefully someone with more experience will respond as well, but my experience with this type of furnace is that this is likely to be a clogged line or gas feeder control device. The behavior indicates that there not enough gas being presented to the unit. Unfortunately this is NOT a DIY type of repair. A licensed plumber should examine this unit. Gas units can be dangerous if not serviced properly. Please seek local assistance frmo a professional.

Bryant 340mav036080 limit switch reset time


The primary limit switch in your furnace is an "automatic reset" switch, and should reset itself within a few minutes.

It is a safety device designed to prevent your furnace from overheating. If the furnace does get too hot, the limit switch opens and the burners turn off. The blower should continue to run until the furnace cools down again. The limit switch should then reset itself (usually less than five minutes).

If it will not reset, try tapping on the switch with a screwdriver or other tool. This will often un-stick it. If this does not work, the switch has failed and must be replaced.

A furnace will overheat for many reasons, but the most common are a dirty air filter (should be changed every 1-3 months), or a dirty evaporator coil (only if you also have central air). Make sure everything is clean and all your vents are open to help avoid this problem in the future!

There are other limit switches in the furnace as well, which are "manual reset". They will not reset unless the little red button on them is pressed. If one of these switches opens, it is best to call a contractor to evaluate your furnace, as an unsafe condition may exist.

Bryant furnace the ignitor does not get hot the furnace comes on ( the blower) runs for a couple of minutes then shuts down lower small blower comes on. the gas is released but ignitor is not glowing or...


Hello, if you have a multimeter you can check the resistance of the ignitor, if it is silcon carbide ignitor the resisitance should be between 40-90 ohms and if silicon nitride it should be between 11-18 ohms. if the reistace is not in this range replace the ignitor. Also, make sure the pressure switch is closing, if it remains open then the ignition seqence can;t begin

Should reset by shutting off power to furnace and then back on With a Bryant if you turn power off and then on, if the thermostat is calling for heat when power is restored blower will run for couple minutes before trying to fire furnace. This is normal

Furnace comes on after two or three minutes off.furnace seems to run to often.


If the blower only runs it is likely due to a dirty filter or too many vents blocked or closed. Sencondly if the furnace runs more than you remember before installing the new thermostat look for an adjustment (sometimes called heat anticipation) and select fewer cycles per hour, this will allow a little lower temperature before it comes on hence fewer cycles per hour.

Why Wont My Bryant Furnace Stay Running


Look on the blower door panel in the wiring diagram there should be a flash code but it sounds like the flame sensor is not picking up the flame and you may be able to clean it
