My capacitor only lasted 1&1/2 nights. It was attached to Analog dial Frigidaire FFRA05L1R1 5000btu AC. It cooled a tear droptrailer no problem,but cycled often so maybe that was the issue. It probably cycled every 1/2 hour. I was using a 2200 Yamaha generator and it wouldn't work with the AC on high until I added this so it did work. I'm thinking I need a bigger capacitor or use the low setting after it cools down so it doesn't cycle as much. Any ideas?
