Lp furnance ignites for 3seconds then shut off.


A pressure switch code means there is an unsafe condition that should be looked at by a competent service tech. Sometimes there is a switch failure, but most of the time there is an unsafe condition.

My furnance keeps turning off and I could go to furnance flip switch on and it only last 5 minutes then shuts off again


You may want to check the limit switch or you could have a issue with the gas valve or transformer. I would check the low voltage transformer first, Sometimes I have found that under load the transformer will open ( quit working) and will close after power is removed and it cools down, It indicates a bad internal connection.

I have a Goodman gas furnance. The furmance kicks on the glow rod lights and then the furnance shuts down after about 60 seconds it goes through the same cycle. The burners never come on. What's wrong?


Gas valve is not kicking in or gas shut offs are off. Can you check voltage where 2 wires connect to gas valve. Can you see blinking lights thru lower door window and count blinks. Code sticker should be on inside of lower door.

You could have plugged orfices in the line coming out of the gas valve. Next you could have a plugged gas regulator.The only way your going to find this out is to check gas pressure before the gas valve during a call for heat and then check it after the gas valve during a call for heat you could have a bad gas valve. Try this let me know what you find Thanks and please leave feedback

The furnance runs fine for about 3min. Then the burners go out. The fan limit is still closed, pressure switch is pulled in, and the manuel reset switch on the flue is not tripped. What's causing the...


On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).
