I work on toshiba drives all the time. Pull it out of the box. Just the six wires ribbon cable four screws. Lay on a table and you will be able to see everything you need clean that heat sink good too.

[@subcoolHVAC]

Sweet , Thanks peterbuilt. I’ll do a follow up 👍

[@ccthepope]

You da man, you go from working on fans with 8 foot blades to fans with 2 inch blades!

[@subcoolHVAC]

If it moves I’ll work on it , or at least try. Thanks CC 👊

[@jasonjohnsonHVAC]

Those damn fans fail all the time. I find them failed on so many ABB's. Thanks for sharing with us

[@subcoolHVAC]

Yeah I find ABB’s out a lot, Thanks for your support 👊👍💯

[@MarcosHVAC]

I have a few accounts where I installed axial fans to pull heat from the cabinets. Grainger sells them with a stainless guard for around $100. Keeps those drives happy

[@subcoolHVAC]

That’s a good tip, Thanks MarcosHVAC

[@stevencossaboon3237]

Nice work Subcool. Looking forward to the follow-up.

[@subcoolHVAC]

Thanks Steven , me too 👍

[@MikeB9771]

Nice work, keep it up

[@subcoolHVAC]

Thanks, will do!

[@HEFTYLEFTY303]

Keep it going man

[@subcoolHVAC]

It’s a going 👊👍

On those sleeve bearing fans, use a light grease (super lube) on them and they should live for another 5-10 years. Ball bearing jobs, forget it, just replace them.
Don't forget to slap some electrical tape on the holes.

[@subcoolHVAC]

Got new motors ordered , hopefully they’ll be RIP in the near future, thanks for the tip Nighthawke70 👍

[@Nighthawke70]

@@subcoolHVAC If it came down to a bar fight on the fans, head to the local computer repair shop. They got a wide variety of fans, both new and used.
But if they are in the 120 volt range, forget it. That's special order.

[@subcoolHVAC]

We have to use approved vendors for parts, they are 24VDC motors

[@garyglenn1445]

Thanks for sharing. Great work!!

[@subcoolHVAC]

Thanks for watching!

[@digitald5851]

Nice job.

[@subcoolHVAC]

Thanks for watching!

[@zekenzy6486]

Great Video. Thank you for sharing. What is Toshiba Q9 ?

[@subcoolHVAC]

Thanks for asking , it’s a solid state speed drive design for HVAC motors.

[@ericbaker5619]

Funny how that control center costs more than your average gaming pc and yet they put those tiny fans in there. Good job toshiba.

[@subcoolHVAC]

They are cute, could make the plugs more accessible too… I quit before I broke something

[@tschuuuls486]

That drive released in early 2009. I guess those fans weren't terrible if they lasted 14 years of 24/7.

[@subcoolHVAC]

@@tschuuuls486Absolutely, They’ve done their job 👍

[@mxslick50]

Why is the bypass light on?

[@subcoolHVAC]

There’s something mis wired in the switch or relay , something else to figure out..

[@sterlingarcher46]

Dam I thought those were just disposable unserviceable junk !
I'll try and fix 'em next time one fails , do you think i could use " universal " grease or did you use a specific kind ?
Cheers mate 👍

[@subcoolHVAC]

I hit with WD-40 to clean out the grit then dropped zoom oil in. Cheers 👊😎

[@DEW409]

@@subcoolHVAC I fix those fans on computers like that all the time. You will probably get months to a year or two before those fans lock up again.

[@subcoolHVAC]

@@DEW409 I’ll be happy with a couple weeks until I swap them, Thanks DEW409!

[@GWN_Garage]

Just curious. I know nothing about HVAC repair 😅 Is there a reason behind using compressed Nitrogen instead of compressed air?

[@subcoolHVAC]

Good question, That’s the gas tank I have available on my truck for purging, blowing out drains, etc. Compressed air could be used if available. Thanks
