I bought a cheap, unbranded 4-post lift on the used marketplace. A month after installing it in my garage, the power unit started blowing run capacitors. My amateur diagnosis is the original cheap motor developed a short in the windings and therefore had to be replaced. This Vevor unit had very similar specs, so I bought it. Installation was a breeze as it swapped out without any additional parts or materials (except for the wiring to give it power). I should note that the original motor was a 110v version. I opted to change it to this 220v version because, although I could run either voltage, this is much better on my wiring running at ~7amps on average vs. 14-15amps @110v. I made a video to show my troubleshooting and upgrading to this unit if you are having problems with your lift power unit. https://youtu.be/C023IYbAyeQ
