Problem: I have a bad igniter is there anyway to light a gas furnace manually?

Problem: I have a bad igniter, is there anyway to light a gas furnace manually? My family is cold please help!

Solution in an Emergency Situation: An Emergency situation would be a situation where your furnace ignitor goes out in the middle of the night, on the weekend or holiday. It is Super cold outside and you need to get heat from your furnace to protect your family and the pipes from freezing. We have had many customers who are cold and without heat over the years on the weekends or Holidays. They do not want to wait on a service tech or wait on shipping for a new ignitor. They need heat as soon as possible. I feel very sorry for them being without heat when it is real cold out! I decided I would include this YouTube video on how to light a gas furnace manually on our website. Below we have a YouTube Video which shows how to manually light a furnace when the ignitor fails. I only provide this video because I do not want to see anyone be cold when they could actually have heat in their home. Changes in the video that I would make would be to: (1) use a long wooden match instead of the lighter. (2) Make sure the match is burning when the draft inducer comes on. You must make sure the burning match is sitting in front of one of the burners before the gas valve opens. The worst mistake would be to allow gas to come into the furnace and then apply the match. This could produce a  mini-explosion or fire! (3) You should control the furnace On/Off using the electrical switch (like a light switch) usually located on the side of the furnace. This way you are not depending on someone else to turn the thermostat up and down and you have immediate control of the furnace.  The match needs to be burning and sitting in front of one of the burners before the gas valve opens. Please remember the gas valve is only going to be open for 7 to 10 seconds and if the flame sensor does not sense the furnace flame then the gas valve will shut off until there is another cycle. Below we have a YouTube Video that shows how to Manually Light a Gas Furnace when you have a bad igniter. This video was made by Chris Swain. Thanks to Mr. Swain for making this informative video. I hope this will save you from having a cold home.

Please send us your furnace’s model number if you would like for us to use one of our online parts programs to recommend a replacement ignitor for your furnace. On Bryant Carrier furnaces we will need the product number. On Rheem Ruud we will need both model number and serial number. All other furnaces just the model number.  Our email address is: support@arnoldservice.com. Please click here if you would like to see the furnace ignitors we sell.

  1. I bought this house almost 4 years ago, AC working fine but we had a lot of rain fall and the water level got up in blower. I gently washed it out and it continues to work fine however, there has been what appears to be pipe insulation that was around the power wires going from blower into the house. Now this insulation looks sagging and a wire that appears to be a ground is visible and even a small section of the power supply. Not sure what to do about it meaning can I get more pipe insulation and re wrap it with power off of course or do I need a ac person to look at it.

    1. Hi! I would suggest turning the power off and rewrapping the wire with electrical tape if possible. If you are referring to the black thick insulation that insulates the refrigeration lines then you can hopefully get some new armaflex at home depot. This is what I found when I googled the subject: https://www.google.com/#q=armaflex+home+depot I hope you have a great day! Steve
