Troubleshooting Solutions when your AC Compressor Stops After Few Seconds
If your AC compressor stops after few seconds, adopting a structured approach to diagnose the problem can be immensely helpful. Here’s a methodical troubleshooting guide:
Inspect the Capacitor
Begin by turning off the power to your AC. The capacitor typically resembles a cylindrical object. Check for signs like swelling, leakage, or physical damage. If it looks compromised, consider replacing it. For those unfamiliar with electrical components, it’s recommended to consult a technician for this step.
Clean the Coils
Start by turning off your unit. For light dust, gently use a soft brush. For stubborn grime, consider using a commercial coil cleaner. A good example is the SimpleAir EZGA EZ Green HVAC Coil Cleaning Spray listed on Amazon.
Spray it on and follow the manufacturer’s instructions. It’s crucial to ensure the coils are dry before restarting the AC.
Check Refrigerant Levels
While a general visual inspection can be done (like checking for icing on coils), assessing refrigerant levels and identifying leaks is a job for professionals. They have the necessary tools to gauge the levels accurately and can safely recharge the system if needed.
Examine Electrical Connections
Begin with a visual inspection. Look for signs of wear, corrosion, or any loose connections. Tighten any loose terminals, but ensure the power is off during this process. If you notice significant wear or damage, it’s best to call in a technician.
Check Filters and Airflow
Examine the air filters. If they appear dirty, either clean or replace them, depending on their type. Also, ensure no furniture or objects are obstructing the vents, as this can impact airflow and pressure within the system.
When It’s Time for Professional Help
While some troubleshooting can be a DIY task, certain issues necessitate expert intervention. A licensed HVAC technician can provide a thorough diagnosis, ensuring the longevity and safety of your AC system.

Reasons Why Your AC Compressor Stops After Few Seconds
When an AC compressor stops shortly after initiating, it typically indicates an underlying issue. Here are the primary reasons:
Overheating: Overheating can quickly cause a compressor to shut down as a protective measure. This scenario arises when there’s excessive strain on the compressor. Factors contributing to overheating include:
Dirty Coils: Dirt and debris accumulation on the coils can hinder the heat exchange process, causing the compressor to work harder and overheat.
Insufficient Refrigerant: A reduced refrigerant level makes the compressor work overtime, leading to excessive heat generation.
Malfunctioning Fan: If the condenser fan isn’t working properly, it won’t dissipate heat efficiently, causing the compressor to heat up.
Electrical Issues: The intricate web of electrical components ensures the smooth operation of your AC. Any disturbance in this can impact the compressor. Common electrical issues include:
Faulty Wiring: Damaged or corroded wires can interrupt the power supply to the compressor.
Defective Capacitor: The capacitor gives the initial boost to start the compressor. A failing capacitor can result in intermittent or no operation.
Low Refrigerant Levels: Refrigerant plays a critical role in cooling. When its levels drop, the pressure in the system alters, which can trigger the compressor to stop. Signs of low refrigerant include warmer air from vents, a hissing sound (indicating a leak), and ice formation on the coils.
Pressure Issues: The compressor operates within specific pressure parameters. External factors can breach these boundaries:
Blocked Coils: A blockage in the evaporator or condenser coils can lead to pressure imbalances.
Clogged Filters: Over time, air filters accumulate dirt, restricting airflow and affecting internal pressures.
