[@jman0870]

@@hvacnerd4983 that’s not true. You aren’t supposed to use abrasive cloth because it contains silica, which melts into glass and insulates the rod. If you clean the rod off after you scuff it up, you won’t have any issues. Myself and everyone else I know in this industry uses sandpaper. Never had an issue. 🤷‍♂️

Hey Ted. I appreciate the little observations you show in your videos, like when you inspected the old gas valve and showed that little gap at the wire terminal. It is really easy to tell what you are thinking in your videos based off of what you say and show, so thank you for being so thorough in how you educate.

[@ed6837]

Those are the tough ones. You walk out of there fairly confident but there's always a little seed of doubt.

I liked your videos, reminds me of my days in HVAC. Worked in attics in Arizona with 103 temps which meant 130 in attic. Every house I owned I put a two bulb fluorescent light strip replacing the 60 watt bulb they always install when the house was manufactured.Next guy will be happy to see what they are doing up there.

[@TheHobbyShopFilms]

I had this exact problem with my old furnace, I ended up changing the valve, and that solved the problem. It was frustrating because the problem was intermittent.

[@njmaugbill]

I just love how you clean the flame sensor with a 50 or 100 dollar bill!

[@OGHVAC]

I've had those 2-stage gas valves fail right out of the box. If it's been dropped in the box prior to installation that valve will tend to come apart. I ALWAYS check the physical integrity while at the van/truck. That was a good diagnosis by previous tech but he failed in not doing a flame sensor cleaning. Only takes 5 minutes and it eliminates "wondering" why the flame drops out. Great job Ted 👍🏾

[@taylerellis378]

Dont forget to check your inlet gas pressure!! If its to high the gas valve will struggle to open when called upon. Just a friendly fyi by another hvac tech. May not be the issue here but its definitely something that should be checked and its very commonly overlooked. Take it easy boss.

[@guyinpajamapants6892]

Absolutely! First thing when diagnosing a gas valve, check inlet and outlet pressure. Basic.

[@markcollins457]

Watching your service call looks familiar I'm surrounded with Goodman 80% and the hot surface ignitor can be contrary. They start but dropout from low voltage on the ignitor. I have replaced the flame sensor and it will work 1 day and it comes back. The voltage drop at the ignitor after it fires and a new ignitor fixes it.

[@Daniel-os9tb]

That is a nice setup. No crawling. Just walk over and sit down. Love those. Didnt Get many of them. I used the fancy bypass switch box. Jumper box with a 3fuse. And run through the paces. I always carry terry cloth. No wasting Bill's w me. I always went the one step further and checked gas pressure in and out. But you are right. Sometimes chasing ghosts. Or balance the wrong end of a pencil. Yah, Goodman and Amana valves always going out is common. I always carried 4 and 4 of those durning the winter season. Sold everyone of them and sold out a lot of times waiting for them to come in.

[@bills6946]

When I get intermittent operation, I give the male prongs of the plug a slight squeeze with pliers before I trash a valve. . A little out of round usually makes better contact. If it was a bad connection, that usually fixes it.

[@duttybobb]

[@allenburns3177]

Retired elevator man here. Taught circuit tracing and electronics also in the aprenticeship program. Why didn't you read the ohms on the valve coils? I was a troubleshooter and chased many an intermittent problem. Trust what your meter tells you. Don't touch anything more than necessay till you have found the problem. Seen to many times someone pushes and pulls or resets and it then runs for a day or week and your back again and again. Your quite knowleable and experinced and i enjoy watching you fix these units.

[@tomoliver8498]

Most new gas valves do not have coils that can be measured with an ohmmeter. They have some solid state crap inside that shows open when tested with an ohmmeter.

[@Garth2011]

There is also the mechanical part. Can't read that concern with an ohm meter.

[@Eddy63]

The old $100 dollar bill trick ... Lol ... Good vid and good fix ... Thx for sharing ...

[@sp7864]

You’re failing to check the inducer vent switch. Yes, cleaning the flame sensor is the first thing to check. But afterwards check the vent switch before condemning the gas valve. If the vent switch doesn’t close ( or is weak in closing due to a weak diaphragm) or the tube is restricted, could cause an intermittent circuit to the gas valve

[@ryansmith8083]

I have ran into that more than once. A pressure switch with even 10 resistance will cause the same issues.

[@murkyturkey5238]

[@danwittels5542]

You can't stop a Goodman! Good fix!

[@robertj.2319]

Knew it was the valve on the initial start when you jiggled the wires at the valve and it fired. Have replaced many of those for that reason. Also new valve responds much quicker to the call than the other valve! Those Goodmans came with 2 stage valves where you get a call at w and set dip switches on the board for 1 or 2 sages with a 10 min delay between 1 and 2 or it goes from 1 to 2 after start when set to single stage. I would never have used a $100 bill on a Goodman, they are only worth $1, unfortunately they do not make a smaller denomination! Scrub it with a penny next time. Another good video from the Silver hair HVAC Jesus! I enjoy watching them.

[@AllTattedUp13]

Its actually 7min for high heat to fire..just sayn lol

[@AllTattedUp13]

I had this same exact situation last winter on a goodman. Valve worked when it wanted put new one in, fired it 5-6xs worked. Putting doors back on wouldn't ya know it lol...I ended up changing board too.

[@allanbrito13]

So you did the valve and same issue? I ran into this out in the field a few days ago. It was cutting out just like in the video except the valve never failed to open. It only randomly cut off at startup

[@AllTattedUp13]

@@allanbrito13 if it cuts out b4 ignition I'd look really close at pressure switch, bad limits, chk molex pins are pushed in. Had that bunch times. Find pinhole, hairline cracks in press sw tubing, 90% find lil bit of water in belly of pvc. Been on many call backs that new techs are quick to diagnose 🤷‍♂️

[@tomwalker9184]

I've seen this problem several times b4 where water has gotten into burner box either from roof leak or condensate over flow. Change the gas valve solves most of it, but sometimes both the valve and the board.

[@DA-PICKLES-VR]

Solder joints behind molex plug on the board is the usual suspect for me. When you push on the plug it will work for a little while. I always pull the board and look on the back side

[@taylerellis378]

Another thing to look out for is the ground wire on the burner rack if its loose she will have issues as well. Found this issue on a few carrier infinity units :)

[@GreyRockOne]

Nice work. That old valve (after removal) appeared to be coming apart, looks like a problem to me, you didn't comment on it.

[@benkuxhouse787]

I had a call similar to this on a carrier furnace a few years back. It was the gas valve it was something internally loose on the connections. It would work from time to time. I jumped out all the safeties make sure that was nothing else still not an easy thing to diagnose. Anything else wrong it will still cut the valve out. They only have a millisecond when the gas stops flowing and trying to check it with your voltmeter

[@southernrrman]

Hope you make enough to someday have shoes. Gotta be tough to go in attics with stocking feet. :)

[@bentrujillo6406]

I had one like this a couple weeks ago on a Bryant furnace. I ended having to change out both the board and the valve. The one I had it would run then it would cut out then it wouldn't lite eventually and then go into lockout.

I find that just cleaning the sensor does leave a bit of doubt, but now I test the sensor before cleaning to be certain.

[@gocubsgo5055]

I move the 12 pin or low voltage harness around on the board in these situations to see if it is the board. I've had this happen several times too!

[@AllTattedUp13]

First thing I do on any my no heats...move molex around and give wires going into them a lil snug push. Be surprised how many times u doing that and WOOSH heat fires off.

[@seangriffon6502]

Ted. I have to wonder if maybe there was some corrosion on the terminals inside that molex connector that plugs into the valve as well as the terminals on the valve itself as it fired when you wiggled the connector. Looks like i see a lot of corrosion on the top of tbe burner box like maybe the ac condensate is leaking down into the furnace and it got into the connector of the valve. I have seen this many times. I just take some electronic cleaner spray and use that to clean the male and female terminals and that usually corrects the problem. Also i check the condensate line coming out of the coil drain pan, and find it to be loose, so i make the needed repairs to it as well. I have seen many rusty flame sensors caused by a faulty ac condensate drain line connection due to water dripping down into that area over the summer time, it's one of my most common service calls when the customer turns on the heat for the first time of the season and there is no heat. Hope changing the value fixed your problem.

[@Garth2011]

There's more to consider with gas valves...safety concerns. If they stick and won't open, they will also stick open and not close just the same so the only fix on a gas valve is to diag and confirm the gas valve is not 100% working then, replace it, even if you can do a repair on it. Liability is on you if it's repaired vs. replacing the part plus the safety hazards need to be taken into consideration. Just an opinion...

[@jasonjohnsonHVAC]

Dont forget to clean the burners, check flame signal on ground as well. A lot of times that gets overlooked. Not saying that was your issue on this call. The molex plug can also be the issue. These manufacturers just slap this equipment together as fast as they can.

My DIY instincts would use an Ohm meter to confirm the flakey gas valve internal coil connection. It can be repaired without even removing the valve... The coil windings inside the gas valve are friction fit into vee shaped slots on the back of that Molex connector. That junction oxidizes and eventually fails to make a reliable connection. A quick scrape and some solder will fix that forever. The reasonable responsible pro repair is exactly what you did; just replace the valve! lol, The replacement may eventually have that same problem... sooner or later.

[@jman0870]

I would never attempt to solder anything in a gas valve. You assume all liability for homemade repairs and when that homemade repair makes fire you are flirting with disaster.
