The run capacitor for my AC system keeps blowing, sometimes in less than 3 days from the time I replace it on the air handler of my Rheem system. The compressor and air handler are both 10 years old, so I'm thinking wear and tear on the motor windings and exposure to salt air (unit is near shore) has upped the resistance in the motor and it requires more juice to get it to start. Once running, everything is fine.
The capacitor - AmRad P/- VA2000/37-156K RHEEM P/- 43-20847-41 --------- 15.0 MFD 370 VAC Oval Run Capacitor
- Is the solution here to move to the next higher microfarad level? Say going from 15.0 to 17.5 or 20.0?
I"ve been buying the replacement capacitors from Grainger. Is their quality OK, or should I go somewhere else?
