Hi all,
My Kitchen Range Hood fan has stop working after about 17 years. I went out and bought a replacement motor to replace it, after about a month the motor fan has smokes coming out and stop working, the plastic that cover the copper wire had melted. I took it back to the store that I bought it from and they replaced with a new one, after I put it back the same thing happened and they gave me a new one and I also bought a new switch. But after I look at the wiring of the switch I desired not to install the switch and just install the motor. After about a month with the third motor the same thing happened again, the fan stop working, the plastic cover melted and smokes coming out. When I touch the motor it was hot to the touch. We finally found the flyer the have the information about the name of the company that the Range Hood was manufactured, so I called the company and went to buy a replacement motor. The motor I got this time does not have plastic cover like the other one. But after I installed and my wife was using the fan for about a short time the motor slow down and stop. After it cool down I can turn it on and it run again. I called the company that I bought the motor from they refer me to the installer and suggest that to have them to come in and take a look. I called the installer and he suspect that it's must be the switch and suggest that I replace the switch. So I opened up the metal plate the cover the wire nut where the wire from the switch goes into connect with the wire from main circuit board and found that the BLUE wire from the switch connected to the RED, the RED from the switch connected to BLACK. This a puzzle to me the way it's being done. My question is should I connect my new switch with the same color together? (RED to RED, BLACK to BLACK and BLUE to BLUE).
Thank for any help with this.
