Problem: I forgot how to wire up the dual round capacitor that I purchased from you. How do I go about wiring it up so it doesn’t blow the capacitor up again?
Answer: Thanks for your interest in our website! You would need to look at the wiring diagram that came with the unit. Usually, the wiring diagram is glued to one of the panels on the air conditioner. Hope you can read it. Round dual capacitors on the top should be marked: Herm, Com, and Fan. Rule of thumb on wiring the capacitor is: Herm on capacitor goes to the start winding on the compressor, Fan on capacitor goes to brown fan wire that goes to the fan, and Com on the capacitor comes off one leg of the contactor to provide power to the capacitor. There is usually more than one wire connected to the Com terminal. The Com terminal is used so other components like the fan motor of the air conditioner can steal power from the Com connection. Below we have two YouTube videos that explain how to troubleshoot Air conditioner and heat pump capacitors. If you have any questions please email us anytime: firstname.lastname@example.org. God bless you and your family today and always. Sincerely, Steve Arnold
