HVAC: How To Reverse Direction For a ECM MOTOR (Reverse Rotation/Polarity For X13 ECM MOTOR)

[@mixter7x7]

Don't cut / splice the wire. These " molex " pins are easy to de pin. Reach inside the plug with a small pick or paper clip from the terminal end. Press down the holding fixture / catch and slide the entire terminal backwards out of the plug. Bend the pin slightly out to ensure positive catch and reinsert the entire terminal into the plug in the desired position. You should be able to unpin and re pin this entire plug in less than 2 minutes. Yes - it's that easy.

Your video saved my ass..... im a 12 yr tech and never had this problem till today.

[@DD-ov2kp]

Thanks for sharing this. This was my airflow culprit. The replacement module for a blower was blowing in reverse and had I no idea after wasting cycles trying to figure out why the blower wasn’t blowing faster even after messing with controller board CFM settings. Sure enough, reversing the polarity like you demonstrated was the fix.

[@shaneevans8963]

If you had a terminal pin kit, you could remove the pins in the molex connector really easily and just switch them that way. I've had to rewire so many ABS harnesses this way.

[@hullinstruments]

Yep and usually you can get away without the kit, most connectors and terminal pens are accessible with a tiny screwdriver or straightened paper clip.

[@trinito97]

You can use a pin tool to remove them instead of cutting

[@WallstreetCatalyst]

Thank you so much!!!! You really saved my day!!!! I bought a new module for the ECM motor and looks like it was wired wrong.

[@izzybell11]

Interesting and helpful video. Thanks for sharing your knowledge w us. Great 👍 job JMT.

[@juliusgrey6487]

Thank you jumper man . Now I can stop throwing away money on replacement motors ...

[@sherwinalvarez7365]

Ah another use for my Molex pin pusher. I used that tool alot when i worked for a PTAC company.

[@zekenzy6486]

Great Video. Thank you for sharing

[@alexeytech1495]

Great visual material. Great 👍 information.

[@Atsa-x7i]

Thank you and have a great day!

[@duckluver2001]

I reversed polarity by following those wires back to their connection point and swapping them there.

[@arisbaldos3841]

thanks for the info, save my day

[@alexeytech1495]

Great visual video. Good information to know.

[@zakhu4971]

hello from iraq with you well done

[@Gaynej]

Worked!!

[@dk4855]

I have one I need to reverse right now. The wires are red,blue and yellow with blue in the center. So the red and yellow wires are correct wires to change? 3:35

[@charlessthornton6859]

Which Molex tool is used to remove the wire connectors? I have a new Emerson x13 motor that is running backwards (out of warranty). Purchased 6/2/2021, installed 12/20/2021, evaporator/line freezing now that hot weather is here. Help will be greatly appreciated!!

[@JumpermanTech]

Cut the wires and wire nut it! Not sure about the molex tool. Thanks for watching🔧⚡️🤙

[@Garth2011]

@@JumpermanTech I'd guess you could reverse the source plug wires as well?

[@thesilentonevictor]

Great skill set

[@nonyaanon6801]

I had a motor not do anything, so i ordered the ecm module, the blower then started to turn about a half an inch to two inches in both directions kind of going back and forth??? called for tech suppt they wouldnt answer, the box i bought the module was opened at the supply house, and a thumbprint was on the inside of the module, made me wonder if a customer brought it back and it is no good? at this point have no help or direction. any help would be great?

[@mansourramzey7711]

So this can be done without changing the motor? Tks

[@leons893]

Is this the same process for a 230/240v motor?

[@zxi750r]

Lisle Wire Terminal Tool - 56500... super easy to use.. bought tool at auto parts store for $16...

[@badbadbob1]

Thank you.

[@theprospecto.2836]

How you change rotation on a single phase ECM motor?

[@jackrepak8834]

What gauge connector is this? Thanks!

[@star-ke6fq]

Sir.. Can a fitter work in hvac field

[@cristianbivolan708]

What happened with the burned component inside the ECM, what was the cause and why didn't you replace it

[@Garth2011]

Cheap materials and a flawed design. Those modules are $800 to $1,200 to replace...almost the same price as a complete new motor assembly.

[@MarioDallaRiva]

Like I tell my wife: Give me some slack 👏🏻👍🏻

[@craigforster9861]

Depin the connector.

[@Garth2011]

Those Gentec X13 modules aren't reliable and expensive to replace. They aren't worth $800 or more if they are going to keep on failing. Those modules should be redesigned by the manufacturer and given a 10 year or longer warranty to make up for the ridiculous past.

[@colinrogers5419]

Would be much easier to de-pin the connector and swap the wires

[@timboc105]

Why don't the damn manufacturers of these garbage variable speed motors tell us this? A simple little piece of paper in the box with literature and diagram would be useful. Be Nooo that's asking to much of them!!.
