Wow, it worked for my old XL80..! 😳I must admit I had a mocking smile after watching your video! 🙄but I still gave it a try and tapped the gas valve (ok to waste another minute after 2 hours of troubleshooting) and it started. It teaches humility: I should know better after seeing my mom as a kid yanking the car carburetor with her shoe when stuck in the middle of an intersection!😅 Thank you!
After a few hours of scouring the internet I fall upon your video. Furnace mechanics is simple enough but I would not think a gas valve could stick. Moreover, I would not think hitting it a few times would get it to work, like an old tv back in the day. Sure enough after a day and a half of using the stove for heat, your trick worked. Of course I will replace the valve but now I know it is the valve. Thank you.
Thank you! Just worked for me on my old XE80. Last night it stopped firing up, no heat. Got up this morning (54 degrees in the house, 17 outside) and found this video after trying to manually light the burners to buy some time. Turned the on/off gas valve knob, tapped on the outer valve body, said a few choice words and voila...HEAT. Still warming up the house so we will see if it fires up again.
Enjoy your videos. It’s nice to find someone with the same exact furnace.. I’m not sure if you mentioned the bottom panel has a safety switch which you have to hold or bypass. One common thing everyone needs to do is change their filters or your unit will actually struggle.. having the right Merve is very important. Most of the parts on these furnaces you can change yourself. I’ve been buying spare parts even the control board I found on Amazon, which you know a dealer is gonna charge you three times the cost…
Mines doing the same thing. Tapped on the gas valve for a year now. Think I finally ran out of time. But bad timing. Supposed to be 0 degrees for a week
lol - i know the feeling. the furnace could fail anytime during the winter months but it has to fail on the coldest day of the year and most likely at night or on the weekend or on a holiday! :)
I have the same issue, I replaced the gas valve and still no gas. I put the old valve back on and fired it up and still no heat coming from the burners. I shut the unit down and traced the wires to the board and started to clean out some of the dust from the contact wires. Flip the power back on and I got heat. But it is intermittent, I think my issue and could be yours (if you haven't figured it out already) is electrical. I'm no HVAC guy, but I've repaired enough shit to get in there and mess around and figure things out.
Thanks for the post:). It's that time of year when the furnaces fire up and problems occur ... mine ended being the gas valve. Like yourself, I typically a fairly handy person and like to tackle things on my own if possible. In this case, I found a gas furnace repair person who replaced my value (I recorded effort in my take 3 video (linked in the description - I figured since I was paying for their time I might as well record it for others to learn from:))).
@@RealWorld thanks again! In 10 more years, I'd love to see these millennials try to repair some thing. I had to help this 25 year old change a tire the other day.. all I could do was shake my head in disbelief. Anyways, keep up the videos, they do help!
Got an xe 80 out of an old house... Code flashing pressure switch but. Im wondering if moter should come on 1st... Looking for like a sequence of wat should b happening in order
Thank you RealWorld! That is very helpful. I have the exact same furnace as yours. Inside the furnace, mine has foams on the 3 other sides (except the one for the filter) that are screwed to the furnace wall surrounding the blower. They are dirty. Do you in case know what they are for? I want to remove them. I cannot tell from the video whether your had or not. Thank you!
Glad to be of help ... always good to share knowledge!:) Not certain is you viewed the third video which might be of more help - ruclips.net/video/Y9TtwlZhjiQ/видео.html ... I do not recall removing any foam padding.
Just commenting in case anyone else has this problem. If the status light isn't on check your control board. Make sure there is power going to the board and inspect the outside of the board for burns/corrosion. Probably have to order a replacement board if power is getting to the board, if not then you will have to figure out if your outlet or power supply is bad or has a short in it somewhere. Also you will most likely have to order the control board through an online retailer because TRANE wouldn't sell to me directly as they said they don't sell directly to the public (at least at the trane store nearest me). Make sure it's the same part number too or is a replacement part for your part number. Also make sure you take a video of all connections before you disconnect the old control board. Also be prepared to either pay alot or have to wait a week or two for your part to come in. So there is an argument for calling a professional if you either aren't sure how to do it or can't locally source the part from a store.
9 Year Old (New in 2009) Trane XB Furnace (Propane) Has Trouble Starting. Need Suggestions. Model # is: tuc1b080a9421ac Already cleaned filter, removed flame sensor rod and used steel wool to clean off carbon deposits (wasn't very dirty), blew air into vacuum switch. All fans seem to be working. Igniter glows o.k. When turned on, it gets as far as glowing, but doesn't ignite. I switch it off and start it up again. This time I cup my hand and tap the air intake (PVC) pipe when the igniter clicks and glows. This action seems to do something that allows the propane to ignite, then it runs fine. After temperature is reached, shuts down o.k. Then the same thing happens when there is a call for heat and it tries to ignite again. it cycles 3 times, then the main fan comes on and blows cold air The flashing red light error code I get if I don't intervene is: 2 Flashes (System Lockout) (Retries or Recycles exceeded). It won't ignite, and fans continue to run, blowing cold air. I temporarily solved the problem by taking a red plastic cup, cutting a hole in the bottom of it (about the size of a quarter) and placed it over the intake pipe. By choking off a bit, the gas is now able to ignite (most of the time, but not always). I'm sure that there must be a better way to do this by making some kind of adjustment somewhere, but if so, I am not aware of what to adjust or replace. Any suggestions appreciated.
Keep us posted Reed ... sounds like you are on the right path. Unfortunately, I have a similar question and would think the same - must be a better way:).
@@RealWorld After watching part 3 of your series where you determined that it was a bad gas valve, I decided to just leave well enough alone. It's working 99% of the time, and my "red plastic cup with the hole in the bottom" solution is a LOT cheaper than buying a new gas valve and possibly having to pay a pro to install it. After all, my furnace is nearly 10 years old and will probably have something else fail sooner or later.
@@RealWorld I enjoyed your video and tried some of the simple techniques. When these did not work I called in a specialist. Turns out that because I had closed some of the vents in my house (about half of them to the lower floor while air conditioning in summer) it caused my furnace to work harder when it turned on. Also, the tech put in a new cheap fiber filter instead of the fabric material or hepa filter I had. Air flowed in the air intake by the filter without sucking the filter full force against the unit. This was witnessed visually, huge difference. Upon getting more airflow, my troubles were solved. He also suggested that is is not good practice to have a 15-20 degree spike between a night time setting and a morning setting. It tells the furnace to be on for a long time to bring the temp up, and this inturn causes overheating (4 blinks of the light).

2:02 I love that startup sound
Thank you so much. Watch your video allowed me to diagnosis and fix my problem on the same mode
glad to be of help!:)
right you should read 24 volts for about 3 to 5 seconds only after igniter glows and the there is a call for gas

Same situation here. I tapped on the box a few times and suddenly the furnace lit. I’m now heating up a cold house.
My xe80 sounds just like that when capacitor needs replaced...and it needs replaced every year or two.
good post/tip - i noticed the same at one point although i would think your capacitor should last longer than a year or two.
@@RealWorld you would think, but nope.

@@reedgrele6673 I know the feeling:). My furnace is just over 20 yrs old and still ticking. I plan to keep fixing until a major repair is needed:).
Tanks
This video frustrated me. Unplugging wires, multimeter... turned mine off and then back on and the burners lit.
i did the same multiple times over the course of a few weeks until the restart stopped working:)

GAS valve is bad.
Gas Valve.... get a trained technician.
Yes, agreed:). I do not like to mess with gas for obvious reasons.
