HVAC: How To Check A Brushless DC Fan Motor For Ductless Mini Split Units (BLDC Indoor/Outdoor Fan)

[@allenjshaw]

Thanks for the explanation, my MRCOOL unit control board fried and I ended up with an H6 code after replacing it. After checking resistances like you explained on the fan motor, I ended up with OL so I’m ordering a new motor now. The voltages you specified coming out of the control board were spot on. Thanks bro

Thanks for the explanation, I wonder... is there a way to power these outside the unit? I got one where I have a intermitant vibration issue, the motors are not easily accessable, so aside from just swapping both or and moving it around, had to tell which is the issue, or even if it's motor and not a fan blade issue. Powering them up to spin would help in diagnosing mine.

In heating it’s a condenser fan motor too.

Very Well explained... Easy to understand. I have a question on a Mini Slit compressor Pump Motor "How to Check" ? like this Video

Hello, 👋. I am sorry, if I received any voltage from blue ( signal rpm) ? I have voltage, but in the blue in have nothing. And my motor is not running…. But i have voltage in feedback….. and I have to 310v and 15vdc on wh…..

[@sv6k0a39]

Did the manufacturer provide you with info on the resistance and voltage values?

[@narayanaya5519]

Hi friend could you please let me know the details about what is the purpose voltage between GND AND VCC , what is the purpose voltage GND AND VSP , and finally Fg means what could please send reply .I am ur subscriber 🙏

Hello: I have a GE AHTR12 that I'm repairing I just noticed something odd in my case that I would like to point out, I have the following readings from the main PCB to the motor: RD Vm = 317 V BU FG= 4.9V YE Vsp= 0V WH Vcc= 14.9V BK GND The "legend" or symbols of each wire I got it from the my motor's sticker. So the odd thing here is, that I do get a voltage on BU FG, but not on Vsp. Again I measure it coming from the PCB. Anyways I'm wiring it the same way how it came from the manufacturer, so I just wanted to point it out if someone finds this useful.

[@marcochavez7007]

Do you check the board the same way ?

[@jamesdonop445]

Do mini split fan motors have frame numbers?
