Question about Ice-O-Matic ICEU220HA Undercounter Ice Machine
My 30" whole house attic fan won't start. When you flip the switch on, the motor buzzes, if you spin the blades manually the motor runs. Do I need to replace the starter capacitor or the motor?
A simple capacitor tester will tell if the capacitor is bad. turn off power, label wires and where they go and test cap after discharging it . to discharge simply connect the terminals together once its been removed( you can use an insulated screwdriver to connect them and discharge any stored voltage) and then touch meter leads to each set of terminals and read the microfared output. the setting on the meter is usually labeled uf. or you can take it to the electric motor shop and let them test it. it has a rating value labeled on the side. usually it has to be within 10 percent of the rated value or its bad . if the cap checks good then the start winding in the motor is probably bad or weak, then a new motor is called for, it is usually not worth the time wait and trouble of getting it rewound etc. take the old motor out and label and measure exactly how and where it was mounted. label and make diagrams. saves a lot of time reassembling exact as it came out. turn off the power , check it with a meter to be sure , short it with a screwdriver to be sure the meter works ,and then treat it as if it was still hot as much as possible when you work on it.
