You said it right, during heating season you definitely see more quirky issues with gas furnaces. At least this one was straightforward with no intermittent issue to track down. Nice repair. Thanks for the video. Stay safe and warm out there.
Furnaces that are not heating then you get there and set the stat and it comes on and runs with no issue, let the rabbit hole begin! Have a Good new year.
They had a recall on these, the plastic drain pan would melt coming in contact with the heat exchanger when the ecm blower motor fails to provide air flow within a specified time following gas valve energizing. The high dollar engineers never thought about plastic might burn which it did coming into contact with the heat exchanger. The real problem was the high limit safety did not open soon enough to prevent this. The board was the fix. There is a orange sticker on front as evidence that recall was performed. The instructions suggest inspecting coil condensate pan for damage if this trips
There are a bunch of those blower safety boards installed in community where I work ( PA). If it's the same secondary board there's a pressure switch installed in the back of the blower housing. It's to shut the gas valve off if the blower stops working and it's field installed. I think I read that Goodman were having issues with failing (melting) evap drain pans and this is a "fix".
The method of detection seems be the Current Transformer around the blower wire. If the blower is pulling current - failed or not - it will think that the blower is running. A better method would be to use a "sail switch" which needs airflow to actuate it.
@@RobertTuck-vo8cwit does use a pressure switch that is installed on the back of the blower housing. However, these kits are junk and are bi-passed more often then not and are replaced with high temp drain pans.
Inducer blower engages, pressure switch detects differential across the heat exchanger and sents power to the igniter saying it's ok to start. The glowplug gets red hot and the igniter safety switch determines if there is enough heat to allow the gas valve to open. A failed flame sensor will stop the gas valve from opening. Simple bypasses can test the individual components. If all the individual components test good, one of the circuit boards is faulty.
That was a very interesting call. Kind of odd to see a 90% in an attic-not very common in NC. Like you I see a lot of Goodman's too, because they are the first choice of builders in new construction. Glad it was an easy fix, and definitely something to keep in the back of my mind if I run into a similar problem on a 90% Goodman. Thanks
Goodman is less expensive to buy but just as reliable and function just as well as the more expensive brands. Goodman gives a 10 year warranty. If sized and installed correctly, will preform perfectly. Goodman parts are on most service trucks. The other brands like Trane and Lennox use proprietary parts that are not always on the shelf at a distributor and much more expensive than standard parts the a Goodman uses. Don’t take my word for it. Price compare an induced draft motor assembly and control boards and you will believe me. The difference in prices is stunning.
@ For the most part the Goodman's are reliable. They have their known issues, but so does every other brand. Unfortunately they get a bad rep because of how they are installed. The budders don't care
Nice repair charies even if it's a, Goodman which I don't like. Just what I needed after watching a pipe doctor video where he was harassing a guy over a dispute charge where from what I have seen it was a warrenty call so Mr pipe doctor should have just charged for labor not the part. So the customer filed a dispute over the charge for the part not the 205 dollar overtime labor charge. But Mr dumbass pipe doctor has proceeded to now file a mechanics lien on this poor custumers property over a 275 dollar overcharge instead of following the proper process to get the manufacturer to cover the cost of the part under warrenty. Thank God for honest good hvac people like you charies and jake and Ted Cook and even Curtis in Georgia who do warrenty calls the right way. And are honest. And charies I am happy to send you the link to this latest pipe doctor video. Take care charies and keep them coming.
I’m retired now after 40 years in service. This is the first time I’ve seen that board. It seems like the technology is changing daily. It’s impossible to keep up with it. I worked for a train dealer and most of the time didn’t know about control changes or upgrades until I saw it on a service call. Nice trouble shooting
mine i can hear relays clicking. flame igniter heats up (bright orange glow) tehn 1-3 seconds later blue flames "whoosh" up (all 4 pipes) 1-2 seconds later relay clicks and shuts off, rstarts same thing again, restarts.... over and over and over again.. never had this issue over 9-10 years and never cleaned ever, ( on SSI) cant afford it .... otehr vids said flame sensor needs cleaned! ???
I've worked on that Modell up here in the great white north hundreds of times as that is one of the brand we sell at the company. I've never seen that little board EVER. must he an American version I guess as that problem is usually the pressure switch that power the valve
@@myHVAClife I've been reading about a LOT of supply-chain issues. It is going to get a lot worse, until enough people realize we need to make stuff HERE, not in 3rd world sweatshops, dependent on communist enemies for a lot of it. For the time being, I'm willing to trade efficiency for lower component counts and easier repairs.

Thanks for sharing, I need to look into this.

It's to shut the gas valve off if the blower stops working and it's field installed. I think I read that Goodman were having issues with failing (melting) evap drain pans and this is a "fix".
I remember that, there also needed to be a transition added between furnace and coil a few years back for low nox.
I need to look into that. Thanks for sharing.

That control board that your replacing won't work on the GMEC model of goodman.was told by goodman to pull it out or disconnect it

Sounds like a troubleshooting checklist!

Goodmans are definitely common, especially with new construction.

Nice 👍🏼 work 😊
Thanks! Appreciate you watching.

Yep! That’s how it usually works.

otehr vids said flame sensor needs cleaned! ???
How many dam safeties ya need!
A few more, lol.

Same here. Seen plenty without that board
It could be a unique American model.
I like heating season, I will trade you cooling season ;)
👍
didn't look like the new board had a light
It was green. The failed board showed red.
@jeromes58 just couldn't see it
I see it now sorry
Didn't seem to be quite as bright. This board will probably quit too.
👍👍👀🇺🇸
Gotta love it!
Another Droneman...well, nice tracing it out; better that the part was available.
Parts are hard to come by these days.
