Contact UsCapacitor: Can a 5MFD replace a 3MFD?
The fan side of the replacement capacitor the guy got (dual cap) was 10 mfd instead of 5mfd (original). The fan would turn on and run for a short time (30 minutes as I recall) and then turn off (motor was overheating). After the guy got the correct capacitor (5 mfd) the fan worked normally and he reported that it ran for 2 hours without a problem.
