The switch, Motor is probably enclosed so you will need to take off the end cap. get a good contact cleaner and with the power off (it is flamable) spray the sw and associated plates. No scrubbing needed, any electronics or electrical supply should have it. Let it dry, start the motor and repeat. Grease and oil the whole unit as needed.

Your boat lift motor will start but not lift the load- This could indicate that there is an issue with low voltage or you need a different size wire; Your boat lift motor hums- This could be the several things; Your boat lift motor will only turn on manually- This could be something wrong with your wiring or the switch.

Quick and easy no cost repair.If the motor Hums, buzzes, or trips the breaker this will generally so... Electric compressor motor that isn't starting by itself.

Start winding is most likely in conjunction with a capacitor (so as to give it a phase shift, cause you are using single phase power) If the capacitor is out it wont start, (unless you can give a good spin) if the run winding gets power, but the start winding doesnt you will get a hum and no start (both act the same) you need both.

The capacitor stores an electric charge and releases it in a burst when the switch is thrown. Typically a capacitor costs $10 to $15 at Grainger. Determine if the motor is seized, if not it's almost surely the capacitor. The fact that the motor hums shows electrical continuity to the motor.

Other Factors that will Cause an Air Compressor and Electric Motor to hum and Not Start. Pressure Switch Settings. Head pressure is too high. Make sure the adjustments for the pressure switch are set according to the specifications of the manual. Bleed off some of the existing tank pressure. Pulley and Belt Tension

The single phase motor hums, but does not start might mean that if it’s a capacitor start machine, the capacitor is not working anymore. It may also mean that the rotor, if it’s wound is now burned out. The best test to carry out is to see if the motor rotates in required direction if given a manual push if possible.

If the hum is caused from the cable TV connections, or internet connections, you can use PS Audio’s HumZero. If it is not a cable TV causing the problem, it may mean there’s a power ground loop between the two pieces of equipment. You can test for this by using an AC “cheater plug” that lifts the third wire ground from the AC receptacle.
