Amana Central air conditioner compressor won't run

If your Amana central air conditioner compressor won't run, the system may have an **AC compressor not running** or **air conditioner compressor won't start** problem. The compressor itself is the most likely cause, but it is not usually the first part to replace. A worn or defective compressor can fail a continuity test, while a failed start capacitor is another common reason the compressor will not start. Next, check the contactor, which sends power to the condensing unit when it receives a signal from the furnace control board. Less common causes include a failed run capacitor, capacitor, or dual run capacitor. Bulging, leaking, or electrically open capacitors need replacement. Turn off power at the disconnect box and circuit breaker before inspecting components, and remember that capacitors and condensing unit wiring can hold dangerous 240-volt electricity. Compressor replacement, refrigerant handling, and any repair inside the sealed system require an EPA 608-certified, licensed HVAC technician. Enter your Amana central air conditioner model number to find the exact replacement compressor, start capacitor, contactor, run capacitor, or dual run capacitor for your specific unit.

01 - Amana 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.

02 - Amana 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 - Amana 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 - Amana 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 - Amana 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 - Amana 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.
