The characteristic of the squirrel cage motor depends on back static pressure. Just like a centrifugal chiller, you can cause the blade to run but not pump anything. Install some sheet metal over the exhaust until the amps come back to the FLA rating and you should be good to go.
Need to create a little static pressure with a piece of sheet metal over the air discharge. Slide over the hole until your amps are correct. Then screw into place. Needs some back pressure.
I'm taking your blower motor adventure to train the guys for sure with this one. Fan amps go down when static pressure goes up because its move a smaller mass per min. Less restriction means more lb of air per min.
yep, you generally have to block one half to two thirds of the outlet with a flat plate, from the middle of blower toward outer edge works best, leaving the outermost part open. I just slowly block the outlet with scrap tin and watch current until drawing just under max rating and screw it to the flange with self tapers, but I have u-bent some to lock on and added a few screws. totally osha approved having the exposed blower wheel and wiring. 🤣🤣🤡
Hey Mikey, of Mikey Pipes Plumbing not easy being cheesy. I like your podcast/social media, looking thru some comments/reply. I guess some of your customers are still checking in on you. Looks like you are running some R-134a again. A lot of bubbles in my sight glass again. I look and talk like Denzel Washington in that movie " Flight" unquote. But I guess, I should been checking the maintenance schedule and refuse to fly you here again. lol. Love you buddy, God bless you my brother in Christ.
Booo! I’ll miss the entertainment of your videos but enjoy the well deserved time off. Thank you. Hopefully dchvac will post more content to keep me educated
With the blower out of the cabinet your putting more load on the fan if you restrict the air on the supply or return of the fan it will lessen the load and lower the amps
10:42 blowing but over-current terribly. usually end up choking the outlet down between half and two thirds with a flat plate to get the static pressure up and current in check. great garage and outdoor work blower(not osha approved) 🥳🤪 ** block them from the middle of wheel out, leaving the outer edge open works best.
Block one side of the housing on the blower..same concept as an air handler pulling more amps with door off...if it has unlimited air it will over amp it needs static pressure to amp properly. Had the same problem years ago till I capped one end and all was good after that.
I've seen then installers I worked with would block off half of the intake opposite the motor to reduce the amount of air intake and lower the amp draw.
It’s definitely because it doesn’t have any static pressure! Fan Motors need some static pressure to reduce amps, it’s opposite if what you would normally think.
I’m just a student learning this in school. But I was told it works better when it pulls from ductwork. I didn’t believe it but it may be true in this case.
🚬 Quit smoking over 40 years ago……..to this day, if I smell a cigarette, it brings me right back to the cravings I’ve overcome like the devil tempting you!
The reason why the motor got hot I think is the extension cord wire was not heavy enough. Probably was a 15 gauge wire and should have been a 12 gauge wire.
I wonder if the an IDS model will work with a Spacepack setup which I never finished installing. I did rough in the 2in tubing. Would be nice to have heat & ac. I was setup for a 5 ton
Our city code requires 3/4" PVC Sch40 only for condensate drains. They must also be plumbed into the house sewer system as well. The secondary must be plumbed outside in a visible area in the eve. (Most all houses here are slab on grade, so the equipment is in the attic, 99% of the time.) 🤠👍
Well?? Chances are that cord is most likely a 18/3 an then we take the length of the cord an multiply that out it’s all ready high in OHMS an?? The hotter the wire gets? The higher the ohms resistance, which will increase your amperage. 🤷🏻♂️ ❤ Edit.. vacation?? What is that?? Lol I forgot what them were I was always too busy for that… but be safe an we hope to hear soon from you..
@@PipeDoctor this is true too ; would draw max amps due to no restrictions due to no static pressure . 🤦♂️ lol I didn’t think of that possibility just jumped to the cord wire size 🤷🏻♂️
Maybe the amp draws high because it’s not pressurizing the duct. I’ve ran across that on rooftops do an amp draw with the door open when it’s free wheeling, and that I amp draws high. Just a thought could be wrong. Maybe it’s just a bad motor.
Is this a 110V motor or 220v ? I you are running a 220V motor on 110V might be normal is draws more amps ?? and runs slower . " f the motor is operated at a voltage lower than its rated voltage, the current flowing through its windings increases to maintain the same level of power, which can cause overheating and damage to the motor or other electrical components. This can also result in reduced efficiency and increased power consumption"
@@PipeDoctor you told the electrician it was a 220 volt circuit to the old air handler how in the f___k was it a 115 motor it was a 220 volt 2 speed motor trying to run on a 115 volt circuit
Props on the red neck rigging of the old blower fan.... but was that fan motor previously powered by 240v now plugged in to 120v? My thought process is that the amps would double and making the motor hot

yeah what he said! same as trying to take an amp draw
with the cabinet door off wont work...
Needs restriction….dig the side adventures. You guys crack me up
First rule we learned and heating class. The higher, the resistance, the lower, the amps, and vice versa.
Congratulations on quitting smoking. Your body thanks you.
I stopped smoking last Dec. after 35+ years. You have some nice high end accounts, good 4 u. Nice install here.

I always put a filter on each side of the blower to prevent high amps and temp rise. Love the vids Mike!!
@@PipeDoctor you should make a follow up video testing all the ways that are commented. 🤘

Very nice video. Quality work. Homeowner may have to many toys.
There’s no static pressure to that fan it’s in the wide open that’s why it’s over amping

Awesome video have a nice vacation
Mikes gonna have nightmares until these damn test results come back hahaaaa! Waking up in cold sweats blurting out codes lol! Time for some Tito's!!!!
We did that with a furnace blower motor at work to !!!!

Right on the money plus the blower motor looks like it seen better days lmao. Thumbs up xVizzeh
nice install PD crew!
I would’ve chopped that tree with my sawzall!! I ain’t breaking my back for a shrub!! 🌳 😅
for farward curved fan. without the AH casing it moves alot more air which mean it will draw alot more amp
Enjoy your holiday mike,well deserved break. Michael uk care home resident

Good job Mikey Pipes and crew. Keep up the good work guys. Make the trades great again. #LoveBosch
the 18agw cord from the old condensate pump is to small. causing high resistance, high heat in the wire, high amperage draw.
Could the old air handler/motor been 240 volt? If It ran on single phase I would expect high amp draw, motor windings and breaker overheating.
The reason why the motor got hot I think is the extension cord wire was not heavy enough. Probably was a 15 gauge wire and should have been a 12 gauge wire.
The Amps are so high because it’s moving so much air without restriction. If you cover up the sides a little the amperage will go down!
just block the outlet instead, from middle of wheel outwards.
Yup-no static pressure have seen this when using mobile home fans for free air blower, too much load on the motor.
I wonder if the an IDS model will work with a Spacepack setup which I never finished installing. I did rough in the 2in tubing. Would be nice to have heat & ac. I was setup for a 5 ton
Blocking off the fan can simulate a load and amps will drop
It’s like testing a blower with panel off
Please note belts drive units don’t don’t matter

It's the extension cord, the resistant is causing the amps to higher.
the cord isn't the correct size
Can't run those things wide open, they like being loaded down with back pressure. And is there a central vac mounted behind th door there?
😂 " No fosforos" means no matches...its ok lol u tried. Congrats on the 1 year!🎉
Mr. Mikey Pipes, need to get a job site fan for the guys to keep cool.
I'm friends with Paul Harvey. Yup 1 of sids sons. I worked there.
Was the minimum 3/4 " condensate drain size on the Florida Master Plumber's test Mikey Pipes?
turbulance causes it to do that. cover the end and it will speed up and the amps will drop.
Well?? Chances are that cord is most likely a 18/3 an then we take the length of the cord an multiply that out it’s all ready high in OHMS an?? The hotter the wire gets?

240v blower motor?
7:30 At least you did not have to go up a flight of stairs with that.
The motor is pulling so many amps because there is no load on it or static pressure
The blower motor has a safety shut off just in case
Whats the rating on the extension chord?
oh my God, another chicken dinner.@@PipeDoctor
2 girls one air handler? at 7:22 🤣🤣
Maybe the amp draws high because it’s not pressurizing the duct. I’ve ran across that on rooftops do an amp draw with the door open when it’s free wheeling, and that I amp draws high. Just a thought could be wrong. Maybe it’s just a bad motor.
hey mikey@@PipeDoctor
You said it was 240 volts
Hey Mikey@@PipeDoctor
240 volt motor?
@@PipeDoctor did I win a pipe dr hat? T shirt in large? 😜
Using a blower motor like that you can’t run it on high it will burn it up. You can run it on low it will be fine.
hey mikey@@PipeDoctor

bad blower=lower cfm=high head pressure=short cycle, if there is high pressure switch.
hey mikey
IT’s designed to be inside an air handler
You have to slow down a squirrel cage. Where’s that electrician
there must be a lot of horror stories about the electrical systems in your area?@@PipeDoctor
