My furnace blowers turn on and then the heat blowers will blow fire into the furnace for about 5-10 seconds, then turn off and the blower will continue about another 5 seconds and the cycle repeats.

Hello Sharon Witherspoon,

No ake or model came thru w/question...(?).

At some point your heater will attempt... via a heat sensor, that the FLAME IS ACTUALLY ON...

These are varied configurations..

As it fails to "sense" the heat it will shut off...
and recycle

(I believe this should only repeat a VERY FEW TIMES... so as to not cause an EXTREME DANGER to the user.

On old style heaters this is done by a "THERMOCOUPLE"

I have every confidence ... if you check the OWNERS MANUAL
you will find the trouble shooting.. will point you in this direction...

Make & model.. and search for you paper on the internet
if you do not have your original papers.

hope this helps.

There are 2 blowers to be concerned with. The main blower simply passes the household air over the heat exchanger to provide warm air for the supply vents. The other blower, which is more important, is the draft inducer blower. This is a smaller blower that starts first to create a negative pressure in the fire box to ensure that carbon monoxide gases will pass up the flue when the gas jets ignite. There is a pressure switch associated with this blower. When the inducer blower starts, it pulls air up thru the flue until the pressure switch activates. Then the gas jets can ignite, warming the heat exchanger. A few seconds later, the main blower will start to warm the air. If the inducer blower or the pressure switch is faulty, the furnace will not fire up.

It sounds like your blower motor is not firing up for some reason. This could be a circuit board issue or simply a dead blower motor. What is happening is that the system is basically sensing that the heat is not being "blown" to the rest of the house and it shuts it self off to prevent damage. After the flame comes on you should hear another motor come on. Also, most furnace's have whats called an error led that will blink when the system shuts off. Each blink represents a different error. You will probably get something about high heat limit reached.

I have a goodman mfg gmp100-4 furnace. When I turn theromsat to heat I hear blowing for sixty seconds but that is all that happens. What should I check first?


Your furnace has a combustion blower on it. If it runs and don't pull in the vacuum switch the furnace will not start. On the combustion blower you will find a little rubber hose follow that hose to the vacuum switch. You will see 2 wires on the vacuum switch connect the 2 wires on the vacuum switch together. If your furnace starts and runs fine for 15 to 20 minutes you need a new vacuum switch. Try this first

in this image A is vacuum switch B is combustion blower

Hope this helps......

Carrier Furnace infinity 96.model 58MVP060-F-18114. Furnace heats


Sounds like it could be your fan limit switch. Part costs about 20 bucks and is fairly simple to replace. This limit switch is a safety that prevents your furnace from over heating. Usually when your t/s is satisfied the blower runs for a little longer after the burners have stopped, and the reason for that is the limit switch. The blower is supposed to cool this limit switch to a certain temp. and once it reaches this temp it shuts the blower off. Yours is stuck:(

The fan limiting switch is acting up. It should stay running until lower temp is reached. It will cycle until the temp stays below or at the low setting. Limit switches are adjustable.

Furnace runs but won't ignite.


Error code 12 is blower on after power up. Meaning: after you turn on power to the furnace for aprox. 60-90 seconds the blower will run. The blower should then shut down and the furnace should go through the start up process, providing that the thermostat is set for and calling for heat. If the furnace fails to start after blower shut down there should be a new fault/error code. However if the blower continues to run longer then 90 seconds and continues with the same fault code more then likely the circuit board is bad. Please let me know if this was helpful and give me a rating. Good luck.
