Furnace starts but wont stay on

Hi, I'm new here,

Don't know a lot about it but here go's....furnace won't start ...if i turn off and on the electrical switch by the furnace, the furnace will start, you can see an element come on and start to get bright...hear a click... the gas(and flame) kicks in for a few seconds ..element goes dim.. gas (and flame) go out.

will do this 3 times then nothing until you turn the electrical switch on and off again.

Hope this makes sense.. thanks for any help

Edit: ok i now realize that the "element" that i mentioned is the igniter switch...should it be staying bright...hence keeping the gas(flame) going?

No, the igniter will shut off once the gas valve opens.

Sounds like either the flame sensor needs to be clean, or something else is shutting it down on you.

The flame rod will be on the far end from the igniter. This can be cleaned with a clean scotch brite pad, or steel wool. DO NOT use sand paper.

Let us know if that don't work after you clean it.

hey

thanks for the fast reply

this happen about a week and a half ago and the young furnace guy around the corner had a look and banged around a bit and got it working...said it might be the board or the motor..but it was working and may work forever so no charge(good neighbor)

I did the same and its working again....

I think if it goes again I'll have someone come and do as you suggested, I don't really want to mess with it.

Thanks again..any more advice would be appreciated...

Smile Furnace keeps going out

Hello, I'm new to this site. I can light my furnace and you see nice flames, it only last for a few seconds and then the pilot and flames disappear. Everytime I light it now, it goes back out.

I had a part replace last winter, because the pilot wouldn't light at all. Please can someone help me figure out what's going on with my furnace. I live in Minnesota and its starting to get cold.

Tricia

Is this an okl style furnace where you have to light the pilot manually and it stays on all winter(when it works right)? Or does this furnace actually automatically spark for the pilot to come everytime the thermostat calls for heat?

What kind is this furnace and what year? Describe if the exhaust gas goes into say a 2 inch white plastic pipe, or is a metal flue pipe used?

Was the thermocouple replaced? If not, then that may be the problem. If that was replaced, then I may call the dealer to see what kind of warranty they have behind the gas valve. and may stand behind it since this was just done last winter.

Furnace keeps going out

Thank you Jay. I will try replacing the Thermocouple this weekend. That part has never been changed. If that doesn't work, I will give the dealer a call.

Have a great weekend~

Have a great day~
