Unseizing A Stuck Inducer Motor Heat Service Call
Vložit

- I am on a no heat service call where the inducer motor is seized. I remove the motor and oil up the bearings. After working the oil in I free up the motor. Put the inducer motor back into the HVAC equipment. Turn the hot air furnace on and inducer starts up. Let motor run about 30 minutes and it kept operating without over heating or amp draw increasing. I still recommend replacing the motor to my customer before another failure occurs. I didn’t want to leave the shop keeper cold until I returned.

I have to tell you. From watching your videos, I have saved a service call and been able to diagnose and change parts on my old Colman furnace, a couple of times now.
Happy you enjoy my videos. Lots of information is hidden away in my vids. Yet many looking for quick answers complain my vids are too long.
This guy doesnt care about his trade. He cares about making some money on youtube. He’s taking money out of licensed and insured contractors by teaching DIYers. Plus he’s potentially puting people’s safety at risk. I’m not an HVAC guy but I’m calling it the way I see it.
Good Job: You are one of the few mechanics that will try to lube inducer motors. I had one I lubed and it lasted more than 5 years until they replaced the furnace. Don't know why more mechanics won't lube them. Thanks for the video.
I have been able to save a few inducers and other motors just from freeing them up and get them spinning properly. Most don’t want to waste time since more profit comes from changing parts than making what’s in front of them work. That or they don’t enjoy failure if motor can’t be revived. Unfortunately I lost many battles with similar jobs.
@@cyounger5716 it’s not a callback when you tell your customer they need a new motor. You got it to work yet can’t promise how long before it fails
@@cyounger5716 Note in the paperwork that it's not a permanent solution, quote them to replace the motor, have them initial the little box where it says accept or decline and have them sign off. Then it's on them.
I wish every problem could be soothed with a little oil. Nice job. I'm sure the store is glad to have heat while waiting for the new part.
Many times this won’t work. Yet rewarding when it does
The great Hacker always has a solution !!
Gotta provide comfort
Hi Bill, and nice job.
You made a statement in your last video about you making the wrong turn being the story of your life.
This storekeeper and all the thousands of followers you have would not agree with that.
Everyone has a bad day now and then, but you seem to do the right thing for everyone you are in contact with
Keep it Up!
Bill you're an inspiration to a lot of us! I picked up more than a few tips from your video's. Hang in there mate, this is tough times for us all...
This video is the best. I did the same thing and it worked. Of course I will replace my motor but for now I have heat. Thanks
There is another bearing hidden on the other side of the motor next to the fan. You can keep pouring oil into the exposed bearing all day and it won't fix it.
I put oil into the rear bearing and the front. Yet many times the oil only helps get out whatever found its way between the rotor and stator. The bearing are sealed on this motor.
front bearing is probably shot from the impeller being out of balance
The front bearing most likely took a beating. What’s the chance something found it’s way into the rotor stator creating friction. Then the oil helped move it out of way? The bearings are sealed. I still recommend the motor gets replaced, I seen some of these motors go years after fixing like this. Others die a few minutes to hours later.
yea, idk, from how it was spinning freely one way i had assumed that one of the rollers had sheered in a way that caused it to act like a sprag, more than likely just working it around could have freed it enough or oil could have gotten in from the back somehow, or there could be another bearing inside near the rotor that failed, cant really tell without an autopsy of the motor
Thought I was the only one that would take the time to try and get it to start 👍
Can’t leave my customer with no heat. I rather try and fail than not attempt to win
Thank you great help
I love a happy ending.
Me too, many times I am walking away feeling I lost a patient
There is a bearing behind the fan...thatz the one becus close to the heat..
Oiled both bearings
@@thehvachacker awsome..your the man !!!!
I've freed some up and oiled with zoomspout oiler, they ran another 3+ years, that way.
Next time connect your drill on the shaft and while spinning it, push the shaft in and out. You’ll find it will free up the motor most every time, not always MOST always.
WOW !
It is always the inner bearing that goes bad. Spray the bearings with electric motor cleaner and re lube the bearings. Vacuum pump oil also works great
Can’t believe the price of some of those draft inducer motors. They wanted $580.00. I managed to find a good one for a fraction of the cost
They are pricey, the one for my boiler is in the $400 range. Then some inducers you can find for around 200
@@thehvachacker out here in Michigan they run about 110. Not too bad but gives the customer heat for 2-3 days.
That's just motor and cooling fan$
You should have that motor stocked. It fits Carrier, Payne, Bryant and lots of ICP furnaces. That was a single stage 3000 rpm motor. They cost $45. Most times you can remove the wheel. If not wheel is also pretty much universal and costs $12. You can cut wheel off with grinder if need be. You got $60 in parts, $75 in diagnostic fee, $125 in labor. Total of $260 would keep the customer happy and you make your money. Not customers fault that you don’t stock the most basic of inducer motor.
Not sure why I need to stock an inducer motor on a furnace I don’t install. Yet customer never replaced it’s still running. I’m doing ac maintenance right now on this unit
@@thehvachacker Because its the most basic of basic motors. You probably replace 10 a winter at least.
I don’t work on a lot of 120 volt furnaces. Usually boilers or RTUs and RTU are 208-460 vac
@@thehvachacker That makes sense. Didn’t know that. My apology. Now I know why I don’t carry 240 volt motors, because I do residential and not commercial. LOL
Next time close your drill down onto the shaft and you can spin it each way alot easier.
Should try next time.
never been more frustrated! completely missing what ur doin, and where ur doin it, when ur not spinning ! uhg!
I think you should replace with new one the sound of motor is bad it should be smooth. Mine is the same problem I replaced with new one from Amazon.
Take the fan off !
Took the fan off
Call back waiting to happen. Cheap fix isn't the best solution
This could never be covered under call back. I told customer this is temp until a new motor gets installed. I wrote it up on my paperwork, customer signed it. Now if a customer doesn’t change it that’s on them. I didn’t say anywhere this repair would last. Even though many times it does. A call back could only happen if I say I fixed this and left it there. It’s on the customer to gamble with this motor lasting if they want. Yet I cover my ass.
@@thehvachacker How long did the Motor Last after the repair ?
Pablo Gaviria still running. If it failed the store owners would authorize repair.
