Exactly right. Many guys slap in a new valve, run a cycle, take the customers check and leave. Always check output gas They are set higher at the factory to ensure ignition in most scenarios. High gas will make the furnace run hot, possibly causing hi limit shutoff and even shorten the life of the heat exchanger. You are a technician, sir.
I was wondering if we need to adjust the pressure when ALL of the gas appliances are on, so that pressure to furnace doesn't drop when that occurs? Or am I overthinking it?
@@cleansebob1 yes you are supposed to. It will say to in the manuals too. Depending on how many units are gas in a house, I may not worry about it because there's typically very little drop in pressure with other units running
Amazing gas valve video. I do have a request please. I'm a new tech , I came across valves not sure where to plug my manometer. Could you please do a video of different gas valves and their port to connect. It could be just a pictures of valves. I like the quality of your videos and most importantly, you show the step by step process. Thank you.
SO thankful for this video! HVAC contractor said I need a new furnace and immediately sent out a salesman. After telling them I wasn’t interested I tore into myself and was able to diagnose and fix the problem. This video helped a fair amount. Furnace will eventually need to be replaced but for now this saved me thousands!
Make sure to check incoming gas pressure before final diagnosis. Most gas valves are internally checked and will not open if gas pressure is too far off. Not super common, but does happen.
Thank you for the video. Our furnace works fine as long as it gets a break between uses of around an hour. Tech said it was the "Smart Valve" which will cost around $1000 to replace. Anything else it could be? Why would it still work when it gets a break but not fire up if you try to use it without enough of a break in between?
Wow Wow Wow! Wait you forgot one more test. If it does not open, tap on the valve several times. The reason for this is the valve might be stuck. The gas suppliers will add antifreeze to the gas from theirs storage facilities so the gas will not freeze. This can cause a little sticky build up in the valve. Once you free it your good for winter. Techs helping Techs
Thanks to your coment about gas valve stock after doing my test using a multimeter l did what you recomend in your suggestions and works!!!! Thanks, my friend!!!!
Thank you for the video. Helped me diagnose my problem. I was just about to order a new control board when I saw your video. I was able to isolate the problem to be my gas valve. I was unable to get a 24 volt measurement at the out of my board until I disconnected the wires from my gas valve and measured it that way. That told me the board was doing its job. Inducer motor, pressure switch and igniter all performed fine. I ordered a gas valve online because outlets in town will only sell to HVAC contractors.
Good video ! Thank you What if 24V to the gas valve is applied only for 1 or so second, Obviously no gas coming out and igniter is off in another 1-2 seconds. Wondering what does it mean ?
Hello friend, I have a question, my heater turns on but after 5 to 10 minutes Riley cuts off the gas and after 5 minutes I open it again and it turns on again and I changed the flame sensor and it does the same to me. It will be the tablet that Riley already it does not work
Looks like the gas valve been replaced before. Why not add a drip leg on the gas line and use a gas flex. Moisture may have gotten inside the gas valve. I always tell myself why did the gas valve failed.
For the DIY homeowner, can the CAT85 Manometer be rented? Obviously needed for tuning the GV. Buying a gas valve is one thing... but if you have to buy a CAT85 Manometer... $$$$$ big bucks for just one time use.
You should check the pressure of the gas before replacing the manifold. Its not common but can happen. The supply could be blocked or not even getting gas.
The only people that watch these videos are homeowners who can't afford to pay a technician to fix their furnace for them and like a complete a$$hat you pull out a 2 thousand dollar combustion analyzer when there is no way in hell any of those viewers will have a set of those laying around.....
Unless your customers are asking you to convert their furnaces into a rocket that can land on the moon you are way overcharging them if you can afford to buy unnecessary test equipment that costs more than their furnace.
Field Pulse... Great Video! To the Point! Very enjoyable! You are very easy to follow! Subscribed awhile bad because of the great content and easy to learn! Thanks Josh!!!
Great video, needed a good refresher since I don’t repair many units being an independent handyman. I am HVAC qualified, few jobs in between. Thank you…
The junk single stage Honeywell has valves with a grey top and small red switch will give you 24 with the leads unplugged, but when connected with short out the furnace, shut it down, then it goes into a retry. If you test for voltage with the leads hooked up to the valve, you'll always see zero. Leading you to think it's a board. Also, I rarely see a 36J go bad. How often do you run into a failed 36J?
Thanks for the explanation. My gas valve is getting 13v before the board sends 26v to it. My HVAC guy replaced the board and flame safety sensor and it did the same thing. Could this be the gas valve going bad or do I have wiring issues?
I have to ask, why didn't you do the pressure test with the meter and try adjusting the valve under the brass screw cap, before swapping the entire pressure valve assembly? Just seems kind of odd that the whole assembly would need to be changed out, when it could just be a corroded valve or something in there, that could possibly be tested and adjusted?? I have no idea, but I couldn't help wondering that while watching the video... Are they that cheap, that there's no point in bothering with that, to avoid a future service call or something?
This video really helped ! I heard the audio click, but that must have been from the mother board ! I will test the wiring and determine if in fact it is a faulty gas valve !
im having issues now where ive found a bad 2 stage gas valve, got a replacement and now the replacement isnt working. reading no resistance on the coil but everything else is right. no problems anywhere else in the system but for some reason this ones got me REALLY doubting myself.
It would be a big help to me to know what model of valve you are talking about and if you got it off the shelf or if it was shipped. The new standard of shipping is to toss a delicate piece of equipment in an oversized box with a single air pillow so that it bounces half way across the nation before it gets to you. Then when you install it you realize that you were probably better off leaving the original device in. What I would like to have seen in this video is some differential diagnosis of: Yes the inducer is running, yes the pressure switch is engaged, but what if there were intermittant problems like the inducer not being steady so that the pressure switch had minor open/closed problems that then might let the pilot light then shut it off? or the flame sensor being intermittant so that even if the mains lit that they might fail too? No bigger bugger than an intermittant fail. Lettuce know if you had any success with your valve.
I just watched another video where a solder connection on the back of that black terminal block broke loose, and all it took was a little solder and flux. I would try looking into that before replacing the whole valve. ruclips.net/video/goarb1XJhDI/видео.html
Use a sharp probe on the high and medium. jumper the high to medium and with the dammit switch taped on, use an alligator jumper from the R redead and put 1 24VAC ion the jumpered high and medium, listen for the click and the gas flow.
Excellent technician! I liked and subscribed. I don't have any issues with my heater and I am an oil heat tech but know very little about gas so you are my "go to guy" thanks for being professional keep up the great work!
Good video, but what is the size of the tube adapter did you use? I have the same valve but I am not sure what size tube I need (although I guess I could try to fit a caliper in there to measure it...)
A good idea would be to check the inlet gas pressure, I had an experience, I checked the power from IFC and I got the 24 volts I assumed the gas valve was bad. I replaced the gas valve, and guess what? Problem still. I checked the gas inlet pressure was above 25 WC. What was the problem, outside regulator. I told the customer call the gas company to replace the regulator, after regulator was replaced, problem solved 😊. High gas inlet pressure causes the gas valve can't open.
My HVAC tech said there was excessive moisture buildup in my gas regulator which might have froze and kept the gas from passing. He was able to get the moisture out and got my furnace up & running again. He advised me to also contact the gas company if i have another ignition lockout issue & have them look at my regulator. I'm wondering if i should just contact the gas company now anyway to have them look at it, rather than see if the problem returns.
No not always but it's recommended. Most technicians including myself aren't always allowed the time frame necessary to do a combustion analysis on every furnace.
As the fellow below says, you need to first check that there is gas going to the valve, before you spend several hundred dollars of the customer's money changing a gas valve that might not be the problem.
Great video... I tried everything in your video and still no help. I actually watched several other videos on diagnosing your HVAC system to no avail. Well, I was about to give up and call a serviceman for repair. Then my wife started making lunch and noticed there was no gas to the stove. I remembered we have an automatic shutoff on the outside gas meter. We live in earthquake country so I installed this valve 30 years ago. We recently had a swarm of earthquakes and the valve shut down our gas line. A quick reset of the earthquake valve and everything was up and running again. No harm no foul.
Voltage on my valve jumps all over the place when the board is sending signal/voltage to it. Goes from -100 to the -190s. My multimeter is set to ACV200 setting. I switched the leads on my multimeter to the other prongs on the gas valve and same results. Does that mean my control board is the problem? It’s a RHEEM rooftop furnace.
Same here. My ignitor sparks but no gas. When I tested the power to the gas valve the numbers on the multimeter are all over the place when the ignitor sparks. I'm thinking my control board may be bad. Have you found the problem yet?
@@KHAOE1 Somewhat temporarily fixed it. I removed and reconnected the harness connector (the block with 9 wires) that is connected to the control board, blowing out any debris that might be on the pins on the board and connector. I made sure it was seated firmly into the board. For now that seems to be the fix until I can replace the board. Make sure you remove the breaker going to the furnace. This is on a Rheem roof unit.
@@KHAOE1 no problem. Side note. After about a week my furnace started having the same issue but disconnecting and reconnecting the same connector fixed it again.
@@crs1474 got it...if I replace the gas valve (Already have one on order) and it doesn't fix the problem I know it has to be the motherboard. My problem first started when it started getting cold outside (My furnace is on the roof). My furnace would not work at night but just fine during the day. I think the motherboard needs to "warm up" or something before it starts working right. Maybe need more insulation inside the unit.
Nice video Josh! Thank you for the time and effort to help others. I'm retired from the trade and remember when I was green at it, circa 1960, and needed this kind of help [ long before the internet existed]. Took me a long time to get up to your level. My tip is that a service tech must keep in mind that an intermittent sticky gas valve can render misleading error codes such as "check flame detector rod" or "check ignitor" when those things are perfectly fine. Intermittent troubles can be challenging for even an ace tech. 17Apr2023 8:02 PM ‹(•¿•)›
Your spot on. Thanks for the great information. I appreciate the compliment. Like you, I never had this type of advice or help when learning this trade. That's why I do these videos. Having something like this would have been such a huge help for me. Thanks for watching.
Look for the label in the furnace. It will tell you. 3.5 wc is a rule of thumb. The manufacturer gives you the exact water column needed for optimal operating temperature, safety and efficiency
hey, i want to thank you for your help. your video saved me around a 1000.00 today.woke up to a cold house called the company that installed my furnace, they told me 198.00 for the guy to come out, 550.00 plus for the gas valve and another 2 to 300 for the repair. called grainger supply got the part for 130.00. they that company must think i was born last night. its a total shame how they take advantage of some people who have no idea.
$850 to $1000 is what I charge, not taking advantage of customers. It’s the cost for a professional service. Glad you figured it out and saved yourself some money though.

It should be printed on the valve or on the nameplate of the boiler.
Look at the name plate. The information is on the plate

Could a bad gas valve cause roll out flames?
Cracked heat exchanger is the usual cause. Verify by taking CO readings at supply vents in the home
Will a furnace run with a bad valve?
You have a combustion analyzer right in front of you but you weren't checking combustion as you were setting the gas valve outlet pressure ???
Lol. That wasn't the point of the video I was making. A full combustion analysis was done after I filmed the gas valve replacement.
