I have basically the same unit and after 17 years the same looking inducer motor went bad. I changed it myself but it was a bitch to get to the screws. without taking the gas valve loose to get the center panel out. I just replaced the board this past month since the spark ignitor would sometimes not light up.

Just used one today and I read the manaual lol

My well insulated 1800 sq ft house has an 80%, 80K btuh furnace (3.5 ton condenser). It's more than adequate, in fact probably just slightly oversized. Noticeably "forceful" hot/cold air from all the vents in all areas of the home. 2-degree temperature difference when system turns on and zero difference when it shuts off. I agree with you; I think that system is oversized for the section of the house.

Definitely 💯 agree 😊 Not to mention the towel in the water heater overflow pan 😅

I dont know much about HVAC but i use isolation pads when installin air compressors in auto shops.. what would you think about putting isolation pads between the unit and the blocks. they are suppose to take the vibration

I never could understand why builders want to stick the water heater in the attic. Even it being in a pan isn't gonna catch all the water should the tank rupture. If that ain't bad enough, it looks like the P&T valve is dumping in the pan.

Ohh charies sorry to comment again but if the return duct is undersized maybe you can increase the size but from what I saw the return size was 14 inches or was that the supply side but all those the ducts looked pretty big like 12 inches 14 inches but if they are oversized I would start with redoing the ductwork and maybe look into having it heat the whole house but I know as a general rule it's around 60,000 btus with gas per 1500 to 2,000 square feet so wgsrz it's square footage of the house is the unit just heating the, second floor to me it should be heating the whole house and same for cooling. But maybe for cooling be zoned. Again I am just trying to follow the logic based off of what you are saying.

Good information given as you work the problem!

Damn, .45 in the supply duct is crazy. You could probably add another .3 for that coil. Supply static is out of control there.

Water heater PTV line going to the pan?? I agree that the ducts seem to be undersized. Foam isolation blocks under the unit would help. After a visual inspection I would have jumped the green wire to run the blower

Nice vid

Rag around bottom of water heater

Great video Charles you granted my wish with a video about static pressures and proper speeds. As for the unit I am not sure it's oversized question is does this unit heat the, whole house or just the upstairs at 100,000 btus that seems like thats more appropriate to heat the, whole house So maybe more supplies need to be added to heat the whole house and set up zoning for cooling so 2 seperate units can handle cooling. Just a thought charles but a good lesson in when building a house on why you design and build properly for the size of the house. Keep em coming charies and defenetely a cheer up from the, awful pipe doctor video today I watched where he trashed a, custumer who is disputing through the new York legal system an overcharge for the part not the labor charge which tells me the part was under warrenty and if the part is under warrenty pipe doctor needs to seek his payment for the part from the manufacture not harass and go after the custumer and seek machenics Leins against his house over a 275 parts charge that he needs to seek from the manufacturer not the customer. As the customer has had no issue with paying the labor charge which was 205 dollars. Maybe charies you should set up hvac in new York. Just kidding.

Nice video! Keep up the Good Work!!!!

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 will be very glad and thankful to receive the thermal camera you are giving away.Thank you.

wait ? is this an outside unit furnace?? wtf.. i thought only the AC units are outside..???

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! ???

We are having this on our new house, new unit. First person said we didn’t have enough insulation in the attic, they put more in and it did nothing. Only happens when heat is on, and usually when it’s pretty cold, but now it does it whenever the heat comes on. Sounds like this is what is happening. I will pass this info along to the HVAC tech.

Nice video... Were you trained by Trane to work on these units or self-taught?

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

Nice 👍🏼 work 😊

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

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

How many dam safeties ya need!

Nice video.... Some manufacturers just need to leave STUFF ALONE!!!! If it ain't broke to try to reinvent it!!!.... How do you like your milwaukee work light? I was considering getting one..

Nice work man 😊happy new year 😊

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

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.

I like heating season, I will trade you cooling season ;)

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.

👍👍👀🇺🇸

didn't look like the new board had a light

Another Droneman...well, nice tracing it out; better that the part was available.

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".

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

I’ve been waiting for a board for a 6 ton hp package unit for 6 wks. National back order. Same thing happened. Messed up a good board with a new fancy board that continually fails

Thanks for the video. Stay safe & warm out there.

Exact same unit as mine. The heat exchanger looked fine at first glance but the back part has rot holes.

I work on copier/printers and we all must share the same board designer that over complicates things for no other reason than they can.

Heard of this. Never have seen it in person yet.

Another nice video.Keep them coming!

👍👍👍

CANT STOP A TRANE

👍👍👍 to the train guy thanks for the video

If it ain't broke, they'll fix until it is!

pull the thermostat, isolate the control wires, and check for cross talk between W1 and W2 on the thermostat wires. IF there is nothing apply 28v from the R to each wire and measure for any ghost voltages to isolate the control wire as the issue. if you are concerned with ghost voltage use the spare wires as drain and wire them all to the common, that will aid in giving the stray voltages a source to drain too.

Carrier keeps us in business and their commercial and residential heat exchangers…..they make sure there is job security

Nothing good comes with zoning unless you have modulated everything, furnace and compressor.

Thanks for the video. Stay safe out there.
