I would deffinatly change the Capacitor. They are normally a dual run type. One terminal runs the fan motor, the other runs HERM or compressor & C terminal is the common for both. Capacitor can be either round or oval if space permits, but make sure the UF numbers & VAC numbers are the same. You can if you must go higher on the VAC number, but not lower. But is best to get exact values. Fan motors with oiled clean moving shaft that hum are either burnt out capacitor or fan motor winding is bad if capacitor change does not work. Avg cap. price is Aprox $16-$20.00.
Had this problem....you need new fan motor if capacitor is good...motor is overheating and the safety is kicking it off...replace
Might want to check the fan motor start capacitor
SOURCE: FAN MOTOR
The run capacitor is probably bad. The run capacitor is usually a two part component. One part serves the fan and one part serves the compressor. Sometimes when they fail the fan will even run backwards instead of just stalling. Replace it.
