Thank you!!! Its 17 (

[@jthwang4841]

Thank you. Very helpful to temporally get the house warm until replacement igniter arrives Sunday. Appreciate it.

[@AmericanNuke54]

I've read all the comments warning not to do this. My heat surface igniter went out on me tonight. Its suppose to be in the low 20s. I don't want to freeze so I'm going to try this. Already ordered the new ones so its definitely temporary.

[@kenc2257]

My Ruud furnace has a spark ignitor. A "failure to light" malfunction usually means there's crud built-up on the spark ignitor. Usually, you can carefully clean the surface of the ignitor. Really though, the ignitors are fairly cheap (less than $20), and available everywhere (including online) so I just keep an extra ignitor in the furnace closet.

This is really educational to watch, when you are in a jam.

[@howardstewart2549]

So, I’m to understand that when the pilot light/flame is not ongoing in your furnace, there is no problem or risk of a gas leak, in the house. This is during the period of time when you are not using the central heating function of your furnace & the furnace flame remains unlit. The central a/c unit is located outdoors, but the a/c reset mechanism is not located in the thermostat, but in the home furnace unit, it appears to me. Am I correct?After changing the batteries in the wall thermostat, I had to push several switches, close the doors to the furnace properly, unplug & plug back in the power to the furnace, & now the a/c fan(outside) works! I don’t understand the workings of the system. Can you elucidate, please?I forgot to mention, I checked my thermostat & there is no controls for reset, as I noticed, in viewing other thermostats on KZbin instructional videos.

[@Mr.PoopyDoobertPants]

Loving the collab videos!

[@EverydayHomeRepairs]

Thx, more to come 🙌

[@DaveSomething]

I've stuck a propane torch in the igniter hole. I have a networked thermostat, so I'd fire up the torch, stick it in the hole where the igniter went, and turn up the temp. I did that for a week while waiting for a new igniter.

[@jamessotherden5909]

I could have used this technique 2 years ago when my ignitor went bad. Thanks for the info, Now I know.

[@EverydayHomeRepairs]

Good knowledge to have in the back pocket 👍

[@Detroit_Dawg]

I did this and now I have heat. I saw no red glow. So when the house reaches temp and stops blowing, will it keep heating, or do I have to light this every single time? Like every few hours or everyday?

[@captaingenius-o1c]

you have to KEEP lighting it ONCE it reaches the SET temperature and SHUTS OFF....When it goes to turn on again, since their is NO FLAME, there is NOTHING to heat the gas, so YES, you will keep having to MANUALLY light it EACH time......

[@NickShoust]

Tis the season

[@lailapolooza]

Dealing with this right now. I changed the heat sensor because I figured that's why the hot air wasn't blowing. Then i turned on the furnace, red flame (is that the ignitor?) came on, but then didn't catch to blue flames, shut down, and did it again. Any advice please besides calling an HVAC guy?

[@Seabass1206]

is the gas on, do you hear the electronic gas valve open, there could be so many issues and if you are blindly changing parts it could be just the piping, i would recommend getting a multimeter

[@YasminPorchman]

What if the fan not working what if the hold thing not working not making a sound

[@ve3plo]

Yup, please also educate your audience what delayed ignition means and what that could cause when heat exchanger fills up with explosive mixture of fuel and air and someone lights it then.

[@UndecidedHobbies]

There could be many reasons a furnace doesn't fire. Being in the trade rarely replace a faulty ignitor vs other issues. Should be left to people with experience to repair it properly. Ignitors are cheap

[@colinpiegore6146]

Puzzling. If there are no safety concerns, then why does my furnace have a label affixed to it with a warning that says, "Do not try to light the burner by hand."

[@diyhvacguy]

Then don’t, you can freeze until your hvac guy comes in 3 days haha

[@diyhvacguy]

Also what about this seemed unsafe to you?

[@turtlepowersf]

It's obviously for liability purposes.

[@d2ds17]

The Q-tip box says not to put those in your ears... been doing it since I was 5. Stop living in fear, you wuss!

[@AyyuBX7]

That's there for legal reasons. Inexperienced people tend to blow things up when they think they can fix something that they have no certification or knowledge in fixing. Often, rules are laid, not because someone thinks it up but, because someone has done it before.

[@Chevytech1977]

Don't most furnaces with a peizeo or hot surface igniters have a failsafe if they fail to light the gas!? I know on my dad's old furnace, his hot surface igniter failed and would shut the gas off within 5 seconds of a failed ignition

[@EverydayHomeRepairs]

Yep, the flame detector is the failsafe. That is why you only have 4 seconds to light the burners or the gas valve will shut off. 👍

[@ajs7878]

There are furnaces out there that use the ignitor as the flame sensor also. Don't see them too often anymore tho

[@samson11105]

@@ajs7878 that's because the gas valve was controlling the logic for ignition. They were called honeywell smart valves and were abhorrently expensive.

[@ajs7878]

@@samson11105 The ones I'm talking about are older than the smart valves. Even the smart valves have a dedicated flame sensor. These the hsi did both without a rod

[@xxDOTH3DEWxx]

The inducer motor is pulling and testing for vacuum, the pressure valve will verify that a vacuum is pulled so that the exhaust gases can be adequately vented out of the house. You missed a step between the inducer motor starting and the hot surface igniter lighting.

[@z95m]

Does the inducer continue to run after ignition?

[@andrewludwig9251]

@@z95m this motor runs THE ENTIRE TIME until the call for heat is satisfied-- if the induced draft motor failed, the flames wouldn't get pulled into the heat exchanger anymore.

[@z95m]

@@andrewludwig9251 Thanks!

[@diyhvacguy]

@@z95m no it only comes ok for about 30 seconds and then when you have ignition, it turns off. That’s why this has to be manually lit every time you want to run the furnace in an emergency situation where your igniter is bad.

[@diyhvacguy]

@@z95m oops I’m sorry, I thought you said the igniter. YES the inducer runs the whole time the furnace is in heat mode because it is always pulling exhaust out of the heat exchanger.

A bunch of people commented on here that they used this trick in the past and got them out of a sticky situation. Just because someone has the knowledge on how to do this doesn’t mean they will do it, but knowledge is power and we are all about sharing knowledge. Also I’m curious but how would one damage their equipment by lighting it manually? Cheers

[@tedlahm5740]

My 1962 gas boiler water heating system uses no electricity. Thermopile for the gas valve and no circulator on the system. all gravity feed heat.

[@williamgunn4691]

This is highly unsafe to do by a non-professional.

[@oshitomaha]

My igniter works, it lights up bright orange/red and I can hear the gas thing click, but the burners won’t come on. How come? It’s a 2020 Goodman (4 burners).

[@Falcon-eh8tq]

But remember, if you're a professional and do this it's potentially a code violation depending on where you live. These units are only certified for use or installation as they were originally certified. IE if it's IPI it stays IPI. Don't do this, get a space heater and replace the HSI for 65 bucks. I'd pay at least 65 bucks just to avoid having to do this repeatedly, I guess if you don't value your time or someone else's safety I've seen guys pull their manometer off an NG gas valve with the burner on and it flashed and started a roaring fireball out of the front of the furnace. He lost most of his facial hair and almost started a house fire.

[@Falcon-eh8tq]

Just aayin.. illegal to run a unit like this voids your homeowners insurance here if the insurance company ever catches wind that a lighter was even near an IPI system. 9 times out of 10 you won't have a problem. But that 10th time if you're not careful you won't even have a chance to know something went wrong

[@CalebKnox]

If the inducer fan has water in it and is not pulling sufficiently this could be dangerous.

[@diyhvacguy]

Actually, It won’t get to the stage of turning the hot surface igniter in and allowing gas in if the inducer isn’t pulling proper vacuum at the pressure switch.

[@RCinginSC]

Now that you have your furnace lit, brace yourself for the incoming gas bill. 😲

[@ASR-BA]

This is not practical and not safe!

[@mcc5483]

Hey my guy, you are so wrong and I really hope to God nobody takes your advice if it's not lighting it's not lighting for a reason. Just because you can do something doesn't mean you should. Say one of those orifices were plugged or the manifold had a crack in it and you had a spill leak and you are now going to go and put an ignition source not in the way of the draft from the inducer, kaboom I've done residential HVAC for over 15 years and I would never recommend somebody to do what you're telling them to do hell look at the install of that equipment you on.

This is for an emergency heat situation. And that’s the purpose of the rollout switches. If someone doesn’t want to fool with it, we aren’t twisting their wrist but this gives them an option.

[@swainscheps]

This is like mechanics not recommending people fix their own cars. Maybe you’re right maybe you’re wrong, but you have a financial interest in people not doing this on their own, which makes us skeptical.
