If you're out in the field then you don't get the reading and you need to turn it over that means that's circuit has a diode in it and it flows one way. There is actually checks for that and you should receive less then 1.5vDC on a diode check setting in the multimeter. If you receive nothing a lot more or it's an open line it means the diode has failed and in most cases will have sent feedback into the controll pcb and damaged IC's.
Thanks for the great video Mitch, again. I've not touched Daikin for a little while, but having this video to refer to will help loads as we are a Daikin service partner. You never know when we could get that fault on a call out! Your Daikin related videos keep me as fresh as I can be 👍🏻haha Have a great weekend mate 🤜🏻🤛🏻 Mick
Nice job Mitch. There is a diode in some of these motors that’s why you need to switch current directions on the ohm test. Your best advice is learn to read your meter. Thanks for the video, stay well.
Yeah mate, I have no idea why they removed the tech info. Apparently the Daikin equip app is the new go to. Apparently it has all the info on there. I’m not sure why they changed.
hey big dog if you get the daikin equip app it has all the info - requires a bit of sign up and isnt as easy to use as the old service app but its handy check out slim tip probes for your multi, I've got a field piece with the adk7 lead kit which has a set of needle probes which fit down the back side of the headers to touch the pins. save depinning and having to think about the order love the vids mate RIP to the service app
Oh wow, thanks heaps mate. I was so annoyed when I thought they deleted all the tech info off the service app. Appreciate the heads up. I will 100% get those leads. The stock fluke leads are chunky as. Cheers mate
Excellent video Mitch!! Slim tip probes save heaps of time on site. You can also strip some scrap tps cable and wrap a copper strand around each probe to give you a fine point for testing. This has saved me heaps of time in the past, keep up the good work Legend!! 🤙🏼
@@handle156 thanks for the tip mate. I’m always looking for ways to get better. Not having to remove the plug would save me so much time on site. Cheers Mark 👍🏻
No worries. A motor can be rewound but the cost of the labour to do so could possibly outweigh the price of the fan motor itself. If it was just a noisy or ceased bearing, then repairing the fan would be an option. In this case, I’d just replace the fan motor myself.
@@maracservices Thanks for the reply Mitch. I saw that the led PCB status light started blinking when the fan was disconnected. So it seemed the board was ok and it was just the fan motor malfunctioning. I replaced it and the heat pump is now working fine. My neighbour had the same issue but the fan motor failing also took out his main board.
Removing the wires out of the molex plug isn't necessary, most of the time you can back probe or lay it flat and just hold your meter probes on the back of the connector where the tabs are. Just saves the time of removing them and reinserting remembering the order etc.
Alright mitch, it's people like you that make us the inexperienced, experienced ,top man

Thanks Mitch for the video.
I'm from Spain and there are many Daikin teams around here.
Thanks Mitch, I have two fan motors and one is definitely stuffed
Cool, I hope this helped

Thanks Mick! I appreciate the support mate. I’m definitely no expert, just trying to help out my fellow Air Conditioning techs around the world! 👊🏼
Leave the wires in the connector , purchase smaller probes
Hey mate,
But some needle point multimeter leads from eBay. I have a couple of sets for this, no need to remove the terminals from the plug
Thanks I was struggling with one today
This info was just what I needed today 🙏
Awesome video

Ahh that makes sense. Cheers mate, I hope you’re doing well!
Top notch content 👌🏻
Thanks mate!
Brilliant Mitch thanks for this.
Please help me I'm having a hard time finding the outdoor dc fan motor part for my daikin RXN24KEVJU5 outdoor unit
Absolutely crazy what they did with that app. Already its hard as hell to get through to Daikin Technical support, at least the app helped somewhat..
Yeah mate, I have no idea why they removed the tech info. Apparently the Daikin equip app is the new go to. Apparently it has all the info on there. I’m not sure why they changed.
Hey dude, I had the same issue. I logged out and back in again and it brought back all the info. Hope that helps great channel
@@brendanmurray6836 thanks heaps mate, I’ll give it a try!

this motor, from inverter Daikin?
That you for the great info
No worries, I hope it helps!
thank, great video... ❤
Thankyou!
Hey man, i have no recistance on my meter. Only when i turn the blades. Does that mean they’re dead ?
Thank you. I have a short circuit between blue and brown (or white brown). Do you think the motor can be repaired or replaced?

@@maracservices thank you. Tomorrow I will look for a new one.
👍
Hi Mitch, thanks for your video. 🙂👍 if the fan motor goes does it take out the PCB?
It definitely can take out the PCB. Not always but I’ve seen it happen many times.
@@maracservices Thanks for the reply Mitch. I saw that the led PCB status light started blinking when the fan was disconnected. So it seemed the board was ok and it was just the fan motor malfunctioning. I replaced it and the heat pump is now working fine.

@@jabberwokky8 sounds about right. It’s honestly a 50/50 chance whether the board gets damaged or not

Thanks mate! I appreciate the tip. My fluke leads are chunky as. I’m going to look out for some better ones. Cheers Adam!
sharpen the tips of the leads with a file or sander ;-)
these new daikins built to self distruct.glad iam commercial must be embarrasing if u do domestic.
Is it possible that the ohm value is in specification but the motor still failure from other electronic function?
