25yr AC guy here and I had to fix my first exhaust fan today. I could have figured it out, it was just a split belt, but I appreciate your video for giving me a heads up about what to expect under the hood.
I must of missed the wiring part. That you skipped. When doing the wiring. You did mention what goes to what. I'm more of a visual learner. Good Video 👍
Awesome instructional video! Quick question though, what size pulleys should be on the fan? I have one that has a large pulley (maybe 8") and doesn't go very fast even though the brand new motor is rated at 1720 RPM.
Hi, I need help. When I turn off the hood at close, morning I turn the switch on, it’s not running until I climb up the roof and press the start button. Then, it works but I have to do it every morning. Is there a way to set it automatic runs without manually press the Start button? Please help. Thanks
If the motor is spinning at its name plate speed your issue may be with needing more speed/higher RPMs which can be done with pulley changes. If the motor is not rotating at name plate RPMs it could be overloaded and require more power to achieve the proper RPM. Manufacturers typically ensure adequate HP sizing for motor in case a speed increase is required.
@@Dirtdigler22 It's good to clean off wheels, but if you do it unevenly and not completely eliminate grease or other buildup you could induce an imbalance and wreck the wheel, driven shaft, bearings, or the motor shaft on a direct drive fan.
Question Tad, I installed new motor this morning, same deal as this, was rotating clockwise , needed to be counter clockwise so I changed the wires per the instructions ( red and black) it worked fine, but I also switched the two leads the white and black.(green is grounded).. Seemed to work perfectly I thought that the white and black wires was for variable speed, one leg didn't test out so I figured only one was hot. Should I take it back apart and switch the leads again or is it fine? I'm much better at automotive, not so much on AC. Thanks
I think you have it wired correctly but I would refer to the motor wiring diagram just to make sure so that you know you're on the right track I like your RU-vid name pretty cool man
