Top view of compressor motor starting capacitor that
blew its top off. This device is used in what is called a "hard start kit".
Every air conditioning or refrigeration compressor should have one. These
devices are also used on high torque applications like air compressors
and pumps. If your system is tripping the circuit breaker on a regular
basis this repair should fix the problem. Please do not install a larger
breaker or fuse to stop
nuisance trips.

capacitor in control box behind motor run capacitor. This control box is
used on a system that is a combination groundsource
heat pump and swimming
pool heater. Notice the wires in the top of the service cabinet. This
box also has a 2 pole Honeywell contactor
and Idec low voltage control relays. The relay in the center of the box
is a GE MARS 165 potential relay that controls the starting function. It
was ok even though this system stops and starts a lot, being on continuous
pump down. Any refrigeration system that uses a TEV (thermostatic expansion
valve) instead of a capillary tube or orifice must have a start capacitor
because the system pressure may not equalize for a period of time during
the off cycle.
If you replace the indoor cooling
coil with one that has a thermostatic expansion valve you may think that
there is a problem with the compressor if it doesn't have one. A shorted
start capacitor can cause the system to trip the circuit breaker.

compressors generally don't need a hard start kit but it will still help.
