Which part needs replacing when the fan won't shut off?

If the fan will not shut off, there are multiple possibilities, so this is a condition that needs to be properly diagnosed.  Once diagnosed, we can provide you with a proper course of action and estimate for repair. Our fee for electrical diagnosis is $110, and I do have openings as early as this morning (4/28).  Thank you for your inquiry, and please feel free to give us a call if you would like to set up a time for diagnosis/repair.
