An air conditioner condenser is an integral part of the cooling system in many households. It helps to cool and dehumidify the hot, humid air inside a home or building by using heat exchange technology.
The condenser then releases this cooler, drier air back into the living space. If your condenser fails to turn on, it can create uncomfortable living conditions in the home and could be a sign of more serious problems.
Knowing how to troubleshoot your condenser and repair any issues is key for keeping your AC system running smoothly. This guide will provide an overview of what causes a condenser to fail to turn on, as well as instructions for testing and diagnosing the issue.
By understanding the basics of your air conditioner condenser, you can avoid more costly repairs in the future.
DIY Troubleshooting Tips
Check the Thermostat Settings
Verify that the thermostat is set to “cool” mode, and check that the temperature setting is appropriate for cooling your home. If all settings are correct, try adjusting them slightly to see if this helps kickstart the condenser unit.
Check the Power Supply
Check the circuit breaker and fuse to ensure they are both in good working order. If all looks good, locate the power switch near the outdoor unit and make sure it is in the “on” position.
Ensure The Outdoor Unit Is Clean
The condenser needs adequate air flow to function properly – remove any debris surrounding the unit, such as leaves and branches, and clean the condenser coils to remove any dirt or blockage.
Potential Causes and Solutions
Tripped circuit breaker or blown fuse
1. To reset the circuit breaker, switch it off and then on again. This will restore power to your air conditioner.
2. A blown fuse is usually easy to identify – it will look burned out or discolored compared to the other fuses in the box. To replace it, use a fuse of the same amperage rating as the one you are replacing.
Faulty capacitor or contactor
1. A failing capacitor may cause your condenser to fail to turn on – signs of a faulty capacitor include rattling noises coming from the unit, slow fan motor speed, and circuit breaker trips.
2. Testing and replacing the contactor is a more complex process, but can be done with a few tools. First, remove the power to the unit and disconnect any cables attached to the contactor before removing it from the unit. Next, use an ohmmeter to test for continuity between each pole of the contactor – if there is no continuity, the contactor has failed and needs to be replaced.
Refrigerant leak or low refrigerant level
1. Leaks can usually be identified by listening for hissing sounds coming from the unit, or by feeling for cold air around any fittings and pipes on the condenser.
2. To repair the leak, follow all safety precautions and use a refrigerant detection system to pinpoint the source of the leak. Once located, clean and seal around the area before recharging the system with fresh refrigerant.
Damaged or worn-out fan motor
1. Signs of a failing fan motor include rattling noises coming from the condenser unit and a fan that is slower or noisier than usual.
2. Replacing the fan motor requires removing the entire condenser unit from its mountings, removing any wires connected to it, and accessing the fan motor itself. To install a new one, reverse these steps – be sure to use a compatible replacement part.
How to reset AC condenser.
If you’re trying to reset your AC condenser unit, the process can be done with a few quick steps.
