Having fan problems. The fan doesn’t run. I can reach in and give the blades a little flick and it’ll kick on and run like normal. Checked fuses. Checked wiring. Greased connections with dielectric. Installed a fan over ride. Same thing. Turn the override switch on and it gets power but needs a little push. Is my fan shot and I need a new one or can I take it apart and clean it up maybe replace a bearing or two.
