If the contactor pulls in there is 24v. A simple test with the meter can tell you that. I learned to always pull the leads off of the gas valve and check for 24.
Walt, keep an older contactor that you know works on you. Connect the 24v going to the gas valve. When calling for heat, if the contactor pulls in? Then your gas valve is bad. If the contactor doesn’t pull in, then your control board is bad, like it was in this situation. Definitely cuts your diagnosing and troubleshooting time in half my boy 🙏🏽 Merry Christmas OG I hope you have a good one.
he should have verified 24v coming out of transformer, if so then make sure flame sensor, rollout and high limit isnt tripped by ohming them out or if they have a reset switch even better. that verifies there isn't a safety tripping the valve instantaneously and ensures that its a faulty board not a valve, unless time delay valves are the new hype! lol
Get a White Rogers 50M56X-843 control board it's for HSI furnaces and you program it with Bluetooth from your cell phone. It does PSC or ECM motors it covers just about every furnace except 2 stage or spark ignition. And they make a board for that too. I carry them in my truck, cuts down on inventory and driving for parts.
Great video! When you replace a gas valve can u count the number of turns it takes to take it off and use that same number of turns to put the new valve if the new valve is identical?
Get a torch light the best I have ever had 1400 lm I’m really picky when it comes to having good light to be able to see the whole front of the furnace working comfortably I tried every light out there the torch one is the best so far jobsmart had them but they stopped making that particular one 1400 lm very bright for this kinds of spaces
Goodman likes to break common at the gas valve and through the pressure switch so it will go and try to ignite turning on the igniter, but the gas valve never open so you will get your voltage at the valve…..that one got me one day and wasted two hours pulling my hair out
That doesn’t prove which way the trouble goes. If you get the correct voltage with the wires disconnected, you know the valve is the problem. If you don’t get the correct voltage then it’s the circuit board. Common sense!
I bet the reason why it didn't fire the first two times after you changed board is because air was in the line after you took apart that gas line. It had to purge
I usually just plug my gas valve into a contactor and pray that it doesn't pull in so i can replace the board.🤣 I am absolute trash and slow with replacing gas valves depending on the setup.
That induces fan sounds like it’s on the way out I have like 30 repair calls every day now that is getting cold again I kip telling people get them serviced before the winter but they love paying the big bucks on the last minute I love stupidity

I NEED THAT COLLAPSIBLE STOOL, HEADED TO AMAZON RIGHT NOW
Nice job

That's a good idea 💡 Merry Christmas

@wundo9372 why the lol?
Could you not just do the same with by taking a voltage reading at the same points?

I’m an OEM guy. But I may keep one for backup. Thanks for the info. Always welcome here
@WWHVAC i agree less trouble
What’s up hvac people! It’s heating season folks.
That’s for sure
Take the wires off at gas valve and test while not hooked up, if that coil on valve is bad it make it look like your not getting 24 under load
I always plug a contacter in to the gas valve wires if it pulls in and no light a no brainer

That's not a bug but a feature on a Goodman.
At least it can't burn the house down.
Sometimes.
🤣🤣🤣
what AI do you use for your thumbnails? Its awesome
Nice video
Define cold Walt? Lol it’s 7 degrees here in Michigan 🥶
65 here and a Lil Nippie
When in doubt change it out
I think ide keep an extra one of those on your Van
Right
Cold out there in them streets!!!
I'm telling ya
How much is usually a control board? I might keep one as a spare. I have a 2006 Goodman furnace
Depends..anywhere from $100 to $2000.Yours probably $100-$250

-12 windchill here in the Midwest. Shit 63 degrees in Texas is shorts and tank tops. Lol
Yall gotta have a different kind of will power to work in that weather
@ worked in -25 windchill in my younger days. Not anymore. Lol
No closed gas valve this time 😁
Thank God our cold (San Antonio, Tx) is not like the cold on the East coast. Do you service the valves also? Thanks for the footage.
What valves?
Hi , fellow San Antonio guy hvac guy here, leaving in Denver , Colorado .
Climate change is real .
Denver alot less snow days than before.
No dirt leg on the gas?
Most guys check for voltage on the wires, disconnected from the valve.
I found if the valve has a high resistance reading you want get a voltage reading with the wires attached
That doesn’t prove which way the trouble goes. If you get the correct voltage with the wires disconnected, you know the valve is the problem. If you don’t get the correct voltage then it’s the circuit board. Common sense!
Good work
Appreciate it
Walt give us two calls. This is very interesting. I would love to try heating and cooling. I just don’t like to be surprised by critters.
I'm sure critters don't like to be surprised by you.. 🤣
You sure don't want to be surprised by the stinging critters...
And get yourself a set of piercing probes for your meter, makes life easier.
I have some, somewhere 🤔
man where you got that bench from, that’s kinda cool. i have to get me one
Collapsible Stool amzn.to/3ZMWBtw
Have to go look at a damn Goodman thus morning myself 🤦🏽♂️
Easy money 💰
I bet the reason why it didn't fire the first two times after you changed board is because air was in the line after you took apart that gas line. It had to purge
He said he had the valve off
Yeah, Gas valve was off when I tested earlier
Man oh man it’s been nothing but bad boards and gas valves this winter. I haven’t got no easy igniter or dirty flame sensor calls yet lol
Big money 💰
It's all easy man
I usually just plug my gas valve into a contactor and pray that it doesn't pull in so i can replace the board.🤣 I am absolute trash and slow with replacing gas valves depending on the setup.
@@Ogtonyg They can be tough sometimes
What do those boards cost around ?
So far it's been inducer motors and boards for me lol‼️🎯
@joemcfarland3491 What have you found going bad on the induced motor?bearing, grounded, etc...
@WWHVAC both bad motors I had was bad bearings.
That induces fan sounds like it’s on the way out I have like 30 repair calls every day now that is getting cold again I kip telling people get them serviced before the winter but they love paying the big bucks on the last minute I love stupidity
You rocking and rolling!
Only half way through this video. I'm pissed off it's not working. Lol
😂
