I am looking to buy a house in forclosure. It has a Tappan gas furnace about 9 years old and there is no manual. Can you advise as to whether the following problem is serious and estimate what the cost of repair will be? Exhaust blower is always on; red light on circuit panel is constant. Then gas flame is ignited and burns for a couple of seconds; yellow light on circuit panel comes on. When blower motor begins, gas flame goes out, yellow light goes out, and red light repeats sequence of 2

Gas heat does not always come on when it is switched on, when it does it works fine when it does not, the house is filled with a bad smell, I'm assuming unused gas. we have had the burners scrubbed with a wire brush before and no problems for 2 years. Can the burners just be replaced? Pilot light works fine. The furnace tries to come on, i can hear it clicking to ignite. Thanks Ronnie from Atlanta
You need to check gas vent ASAP. You should not be getting any odors from your furnace. Have a technician check your furnace. Could have hole in Heat exchanger. If so you and anyone else there are in danger. Please do not operate till it has been che ... Air Conditioners

I have an 8 year od York furnace model P1XUC20N09501C 90%. The problem is the ignitor comes on, the left burner lights, but the other burners won't light. I can light the other burners manually with a lighter and the furnace works fine. My furnace repair guy was at my house and told me to remove all the burners and clean the ends of them. I took the first one out next to the one that lights and cleaned it. (What a challenge and time consuming) It still won't light. Obviously after the rema

Jan 10, 2010 - i should probably give some more info.. it's a ruud silhouette II gas furnace that had been giving me problems with the furnace starting up and shutting down immediately.. i solved this by cleaning the flame sensor rod, although i didn't replace it.. now it starts with a very weak flame and will only light one burner sometimes.. when it does light with all 4 burners they seem to kind shrink in size every few seconds like the gas isn't steady.. this is a new issue, is it possibly
It is possibly related to the flame sensor giving a week signal to the gas valve. You really nee to have the gas pressure checked and the flame sensor checked if you have a multimeter that checks miliamps you will know if it is the flame sensor. You ... Air Conditioners

I have a dayton furnace with a honeywell vr8440p-2088 gas control. The ignition works fine but the problem is I am getting no gas it seems to light the pilot. I checked the orifices at the end of the pilot gas tube and could see light thru it so it was not blocked. Could this mean I would need to replace the gas valve completely?

Actually, after exhaustive troubleshooting and testing, all testing told me the gas valve was defective. I then replaced it. Problem was still there. I then took a shot for what it was worth and went down to purchase a new thermocouple to sense the p ... Honeywell Air Conditioners
Hi , I have a Electronic pilot lighting system on my RUUD package unit. The pilot light flame keeps blowing out or is not working properly. I removed the panel to look and see what was wrong. I could not see any faults. The sparker worked just fine, the gas line tubing was fine no blockages( took it off to inspect it) every thing looked good. Worked fine for the last couple of weeks and now it will not ignite the pilot light to light the rest of the propane gas to heat the house. I tested the fl

I have a Rheem RGDA-100A-AR gas furnace, and I believe the pilot light is out and needs to be re-lit, but I'm not sure where it is. Any ideas where it might be or what it might look like?

Hello, I have a Heater/Furnace problem. I have a Carrier 58RAV095-16 Natural Gas Furnace. My furnace keeps restarting it's heating process. Upon turning the heater on, a small fan will engage and run for about 60 seconds, then the fan turns off and the gas engages and the igniter clicks and you hear the gas combust and the flames spew out onto the heating rods(?) and after a minute or so, the big fan will turn on and begin circulating air throughout the house.

Hi, i am on a pre pay gas meter and when the gas runs out it shuts everything off, which means i have to relight the pilot on my boiler. the ignition won't spark and it takes me ages to get the pilot to light, when it does it stays on. was wondering if it woukd be safe to light pilot with a gas lighter? i know the obvious solution is to have the ignition fixed but can't afford this at the moment, but i don't want to end up blowing my house to bits either, hope you can help.
I use the extended gas lighters for grills all the time. Its safer and keeps me from getting burned while lighting the pilot. ... Air Conditioners
