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
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.
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…..
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 🙏
