There are several possible reasons why your air conditioner might be shutting down after just one minute:
Thermostat Setting: Check the thermostat settings to ensure that the desired temperature is set correctly. If the set temperature is already reached within a minute, the AC may shut off automatically.
Airflow Obstruction: A blocked or clogged air filter can restrict airflow, causing the air conditioner to overheat quickly and shut down as a safety measure. Make sure to clean or replace the air filter regularly.
Dirty Condenser Coils: If the condenser coils are covered in dirt and debris, they won't be able to dissipate heat effectively. This can cause the AC to overheat and shut down. Cleaning the condenser coils may resolve the issue.
Refrigerant Leak: A refrigerant leak can lead to low levels of refrigerant, causing the AC compressor to overwork and shut down to prevent damage. This requires professional repair to fix the leak and recharge the refrigerant.
Electrical Issues: Problems with the electrical components, such as faulty wiring, capacitors, or sensors, can cause the AC to shut down unexpectedly. An HVAC technician can diagnose and fix these electrical issues.
Thermal Overload: The air conditioner may be experiencing a thermal overload due to excessive heat buildup within the system. This can be caused by any of the above issues or a malfunctioning compressor. An HVAC technician can diagnose the problem and perform necessary repairs.
Compressor Issues: The compressor is a crucial component responsible for cooling the air. If it's malfunctioning or damaged, the AC may shut down to prevent further damage.
Undersized AC Unit: If the air conditioner is too small for the space it's trying to cool, it may struggle to meet the cooling demands, leading to frequent short cycles and shutdowns.
To troubleshoot and fix the issue, it's recommended to contact a qualified HVAC technician. They have the expertise and tools to diagnose the problem accurately and perform the necessary repairs or adjustments to get your air conditioner working properly again.
