Sounds like a bad thermocouple.  should be an easy fix.  Thermocouples are cheap and easily installed.  ask for details at any hardware store.

Tractorman44 thanks but misunderdstood husband! When thermostat turned up the fan comes on before flames ignites. Plenum heats and furnace runs.


If the fan comes on first, then the flame ignites, it USUALLY indicates there is a problem in the ignition process of the furnace. Most new manufacturers have the adjustable 'time off' sequence for the blower, and most initiate a call for the blower to run within a pre-determined amount of time AFTER a call for heat has been established. ALSO, and this is where I think the problem is, the ignition sequence starts immediately upon a call for heat. If there is a heat ignition failure, it will attempt a restart. USUALLY, they allow 5 restarts within a certain timeframe then the circuit board locks out the heat sequence until it is reset by cycling the power or cycling the thermostat manually.

What I think is happening with yours it that your ignition sequence is experiencing a 'flame failure' upon a call for heat....then it re-establishes the ignition sequence, which takes another 30 to 45 seconds. During this time, the blower automatically starts (because the allotted time has expired) and blows COLD air because of the initial flame failure. In the meantime the ignition sequence establishes a flame on the second or possibly the third try and then you feel the warm air.

IF this is the case, ultimately what will happen is that the furnace will continue to experience 'flame failure' and eventually fail to the point of 'flame failure lockout' and you will have no heat, but the fan could possibly run continuously.

At any rate, without being able to be there to troubleshoot and test components physically, this is just a calculated and reasonably reasonable guess. What it is telling you is that you probably need to contact a reputable, reliable service organization to give your furnace a good going over before it lets you down on a good cooooold night!!!

I hope this helps you understand the basics of what happens within the system and bear in mind, this is a 'generic' sequence and possibly NOT the exact sequence of your particular furnace.

Can not get fan on to turn on. All else fine. heat only furnace. No air conditioning...only air circulation.I used to set it on "Cool" and "Fan On"and get air to circulate. Do I need new thermostat?


Since you have two thermostats that operate the heating unit and the fan, and the fact that neither will turn the blower on, I would suspect the furnace/ air handler. Turn the thermostat to heat and see if the heat and the fan comes on, if it does operate normally in heat, the fan relay or the high speed on the blower is most likely the culprit. (If the furnace is equipped with a circuit board, the fan relay is integral to the board, if it an older furnace it has a separate fan relay). If it does not operate normally in the heating mode, verify power to the furnace, see if the flame comes on, if it does: the fan motor, circuit board or the fan relay are most likely the cause. hope this helps!

I have a Braeburn 3200 and when the the temperature reaches the desired heat setting. The furnaces heat will shut off, but the fan will continue to run indefinetly. eventually blowing very cold air up


The fan relay is stuck in the on position. When the temperature drops the heater does not ignite because the fan is already running and ignition is locked out after the heat cycle starts an the fan turns on

First, for those of you who might not know, "What is a flame sensor?" A flame sensor is a safety device. When your furnace's main burners ignite (light Up) the flame sensor picks up the heat from the furnace's main burning and says, "YES," and sends a signal back to the main furnace control board saying that it is OK to let the main burner stay on. Or if the main burners do not ignite, the flame sensor does not pick up the heat and says, "NO" to the main control board, Shut That Gas Valve and Main Burners Down! Thank God we have safety controls like the flame sensor. Most of the time, after turning your furnace's power off, you may clean the flame sensors with light sand cloth, emery cloth or steel wool. Reinstall the flame sensor and you are back in business! Over the years flame sensors can build up a light coating of burned-in dust and dirt. This insulates the flame sensor so that it doesn't sense the heat of the flame well enough, so by cleaning it you have almost restored it to its new condition. Seldom, but sometimes they do go out completely.

Our Furnace doesnt seem to be working correct. We an: Air Pro BGM075128 and is Natural Gas. It will turn on when we turn up the thermostat.. but we never get any heat through the vents. There is a...


sounds like the blower motor is not working, if the furnace is actually lighting up and the burns are ignited. You should set your thermostat to auto, as if it is on fan then the fan runs all the time until you take it off of fan. I am a little confused and since I am not there I will give you a website that will walk you through the ignition process, this way we can eliminate flame sensor,ignitor, pressure switch,roll out switch, board,etc. I really hope this helps as I know what it is like to be in a cold house. Good Luck Tim

Igniter kicks the burners on, but about the time the main fan turns on, the burners blow back out. blowing cold air out as a result. plz help!!!


From what you are saying, I would bet you have acrack in the heat exchanger.See if you can watch the burner when the fan comes on. You should see the flame blow out and either move away from the flame sensor or onto a a rollout switch. I'm afraid the only remedy is to replace the heat exchanger or the furnace, depending on the age of the furnace.

Carrier Weathermaker SX model 58SX060-CC Blower runs all the time


Remove all power from the furnace, it is likely the brain in the furnace is need of being reset, from the battery replacement, why did you change the battery, was there an indicator telling you to change it?

Many times just removing all the power to the furnace will do the trick with a reset, if not let me know and we will go from there, but it sounds like the main brain is confused or bad, more likely confused, so try the power removed first.

Than let me know wbwill@sbcglobal.net

Carrier Furnace wouldn't light, fan was running all the time.


Most furnaces have a photo cell if it gets dirty the photo cell does not see a flame so it trips the reset button on flame failure.
