So I got home from work tonight and according to the wife the house was about 48 degrees when she got home around 4:30p. By the time I got home it was up to about 60. Well the temp is no longer rising and when the furnace does kick on it's not getting hot and no warm air is coming out of the ducts. I am assuming the electronic ignitor is shot, but I'm not a heating an A/C specialist. Anyone work in that field?

I'm out in the Columbus/Pataskala area. Shoot me a pm if you are. I'll check back often.

It will kick on an run for about 1 minute or 2 then shuts off. I can get it to kick on at anytime when messing with the thermostat. I don't believe it kicks on by itself at this time. I have to mess with the thermostat, but when it does kick on it runs and shuts off. The furnace does not get hot and the blower does not kick on. I called the company that I had out 2 years ago to work on the A/C and he said he could come out tonight, but with it holding at 60 and we have an electric blanket on the bed which is where my wife and daughter are sleeping at now. I told him to wait until tomorrow. Besides if someone on here does it I would rather them get the money then someone else.

What make, and approx age is it? I had one at my old house that would start and run, but then would shut down shortly after lit. It turns out that the flame detector was "dirty" and not detecting the flame. I put dirty in quotes because it didn't LOOK dirty. I pulled it, cleaned it with a scotch-brite pad, or fine sandpaper, and all was good. Not sure if that's your problem, but it's a possibility.

I do not work in this field, but had a similar issue with an electronic furnace. The furnace would attempt to run, but shut off.The issue was the flame sensor. I had to replace it on this furnace. I know they can be cleaned, but if it is cracked, it will need to be replaced.

Not knowing the details of your furnace, brand/model/ approx. age,

here is a link to some high level info that might be useful to you.

The flame sensor will be loacted usually right near the pilot light. Maybe you can get parts diagram from the furnace manufacture website, assuming you can determine the make/model of the furnace from a sticker right on the furnace?

Yeah there is a error LED on the circuit board. I removed the cover and held int he safety cut off switch so it would cycle. I can here the gas valve open and the hissing for a few seconds then it cuts off. After it finished its cycling and it wasn't able to ignite the LED starting blinking one time. The sticker says one blink is either a gas issue or the flame sensor. I am thinking it's the flame sensor.

quick safety question... do you have a carbon monoxide detector in the house?

If not, you should give a call to the fire department and let them know your furnace is acting funny and you'd like to make sure you don't have a carbon monoxide problem, they'll send someone out to test it... did it for me at my apartment without any question.

nice lol that would have went over well.

the furnace isn't operational at this time. Since I have the panels removed it can't run and I won't be testing it anymore.

Ok the brand is Goodman model GMP050-3

No, I don't have a carbon monoxide detector in the house.

No joking, 100% serious here. Ring in the new year then run to the closest 24hr wal-mart and pick up a detector and put it near the furnace and/or where your all sleeping.

Carbon Monoxide is really no joke and can really put a damper on your holidays... you're probably fine overnight, but it's better to be safe than sorry.

Like I said, don't hesitate to call the non-emergency number in your area and ask to have a fireman check your carbon monoxide levels.

Ok, I found a pic showing a typical Goodman furnace burner.

The flame sensor is on the right, just in front of the burner tube. At the other end, you can see the HSI (Hot Surface Ignitor) glowing to ignite the first burner tube.

If I remember right, the one I had was the same, just opposite sides.
