Garrison Central air conditioner compressor won't run
When your Garrison central air conditioner compressor is not running, the system may blow warm air or fail to cool at all. The compressor is the most likely cause, but it is not usually the first part to replace. A defective compressor cannot circulate refrigerant through the evaporator and condenser coils; a multimeter continuity test showing an open circuit can confirm a failed compressor, but compressor replacement or any sealed-system repair requires an EPA 608-certified HVAC technician. The next most likely cause is a failed start capacitor, which may be bulging, leaking, or unable to hold and release a charge. A defective contactor can also prevent the compressor from receiving power when the furnace control board sends its low-voltage signal. Less common causes include a failed run capacitor, capacitor, or dual run capacitor, which help start and power the compressor. Turn off power at the disconnect box and circuit breaker before inspecting parts, and do not test or replace components involving 240V line voltage unless you are qualified. Enter your Garrison central air conditioner model number to find the exact replacement compressor, start capacitor, contactor, run capacitor, or dual run capacitor for your unit.
01 - Garrison Central Air Conditioner Compressor
The compressor is a pump which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. If the compressor is defective or worn out, it likely won't run. However, this isn’t usually the case. Before replacing the compressor, first check all of the more commonly defective components. If all of the other components are working properly, use a multimeter to test the compressor for continuity. If there is an open circuit, the compressor is likely defective.

Highly Likely
02 - Garrison Central Air Conditioner Start Capacitor
A start capacitor is often used to cycle on the compressor. If the capacitor burns out, the compressor may not run. The start capacitor can be tested with a multimeter to determine if the component can successfully hold and release its charge. If the capacitor is unable to hold and release a charge, or is bulging or leaking, the capacitor will need to be replaced.
Common
03 - Garrison Central Air Conditioner Contactor
The furnace control board sends a low voltage signal to the contactor. When the contactor receives the signal from the control board, it closes the circuit, sending voltage to the condensing unit components. If the contactor is defective, it can prevent the compressor from running. To determine if the contactor is at fault, use a multimeter to test the contactor coil for continuity. If the contactor coil does not have continuity or the contacts a on the coil look burnt, replace it.
Common
04 - Garrison Central Air Conditioner Run Capacitor
A run capacitor will power either the compressor or the fan motor (a dual run capacitor will power both). If the capacitor burns out, the compressor may not run. To determine if the run capacitor has failed, test the capacitor with a multimeter. If the capacitor is unable to hold and release a charge or is bulging or leaking, replace it.
Less Common
05 - Garrison Central Air Conditioner Capacitor
The capacitor provides voltage to the compressor to start it. If the capacitor is defective, the compressor won't run. To determine if the capacitor has failed, test the capacitor with a multimeter. If the capacitor is unable to hold and release a charge or is bulging or leaking, replace it.
Less Common
06 - Garrison Central Air Conditioner Dual Run Capacitor
A dual run capacitor will power both the compressor and the fan motor. If the capacitor burns out, the compressor may not run. To determine if the dual run capacitor has failed, test the capacitor with a multimeter. If the capacitor is unable to hold and release a charge or is bulging or leaking, replace it.
