      All Appliantology tech members are invited to join in this workshop on all things Appliantological: bidness, customers, tools, troubleshooting, flavorite brewski, whatever. Webcams and microphones are open and live!
      This workshop is also a great time for any students at Master Samurai Tech to bring any and all questions about the coursework. We're happy to walk through any concepts you're having trouble with. Think of it like office hours with your teachers. 
      If you have a specific appliance problem you'd like us to talk about, post it here! We need a problem statement and a PDF of the tech sheet or schematic so we can all see it on screen share. If you have a PDF that isn't already in the File library here at Appliantology, send it to us by attaching it to the contact form. 
      Also, follow this Calendar Event so you'll get notified of new posts here. Look for the "Follow" button either at the top of the topic on desktop or below the topic on mobile.
      Who: This workshop is only available to tech members at Appliantology.
      When: Saturday, March 30 @10:00 AM Eastern Time.

It is an option, however do you think you have the technical ability to do it?

Yes you need a license to do sealed system repair/ replacement. Federal law.

Call your local parts house. Give them the AH model #. They may be able to search their database for that particular motor or may need you to remove and take it in. Each house is different. Just have all the info off the equipment handy when you call.

If this were a PSC with cap, it would have been so much easier. But an old ECM motor with integrated controller makes this a very complicated repair now.

My pleasure. Jeff C. is one of the BEST in the business.

Good luck and if you have any more questions, please post here and ask.

Sorry, not motor. For AH replacement, you would need to call in a pro. They need to see the equipment. Cabinet size, fan cfm, electrical, vertical cabinet, txv or piston metering device, outside unit compatibility, lineset compatibility and size, R22 vs R410 or newer refrigerant blend, return opening size and location, supply plenum size, and supply duct size. Probably more too.
