I installed a commercial exhaust fan for a small restaurant/bar a few months ago. Owner called me and said that the exhaust motor goes on for 20 seconds and then goes off for 2 minutes or so. Motor is 3/4 HP 120v. I'm guessing the capacitor is defective. Is there a way to check the capacitor? Thanks for your responses
