When the temperatures rise in Vancouver, WA, the last thing you want is your air conditioner not turning on. At Sub Zero Temp Control, we understand the urgency of a malfunctioning AC, especially during the hot summer months. Before you call for professional help, there are several troubleshooting steps you can try at home to potentially solve the problem. Whether it’s a minor issue that can be quickly fixed or something that requires more attention, this guide will help you understand what to check.
Air Conditioner Not Turning On: Check Your Thermostat Settings
Firstly, ensure that your thermostat is set to “cool” and that the temperature setting is lower than the current room temperature. Sometimes, the issue might be as simple as incorrect settings or a malfunctioning thermostat. If your thermostat is battery-operated, try replacing the batteries to see if that resolves the issue.
Inspect the Circuit Breaker
Next, head to your circuit breaker panel. If the circuit that powers your air conditioner has tripped, simply reset it and see if your AC starts working again. This is a common and often overlooked fix.
Air Conditioner Not Turning On: Examine the Outdoor Unit
Clear Around the Condenser
Make sure there’s no debris, such as leaves, dirt, or branches, blocking your condenser unit outside. A blocked condenser can overheat and shut down, preventing your air conditioner from turning on.
Check for Visible Damage
Visually inspect the outdoor unit for signs of damage or wear. If you notice bent coil fins, remove the debris and gently straighten the fins using a fin comb. However, if you spot more severe damage, like refrigerant leaks or broken parts, it’s time to call in a professional.
Air Conditioner Not Turning On: Evaluate the Air Filter
One of the most common reasons an air conditioner won’t turn on is a dirty air filter. A clogged filter restricts airflow, causing the unit to overheat and shut off. Check your air filter, and if it’s dirty, replace it with a new one to see if that fixes the problem.
Test the Capacitor
The capacitor starts the compressor and the condenser fan motor. If your air conditioner is not turning on, a faulty capacitor might be the culprit. This component is charged with electricity, so handling it is best left to professionals. However, if you’re familiar with HVAC systems and have the necessary safety tools, you can test the capacitor using a multimeter.
Look for Ice Buildup
Sometimes, ice can form on the coils, preventing the air conditioner from turning on. If you see ice, turn off the unit at the thermostat and just run the fan to help melt the ice quickly. Do not attempt to remove ice with sharp objects as it can damage the coils.
Consider the Age of Your Unit
If your air conditioner is older, it might not be as efficient or reliable as newer models. The age of the unit can impact its functionality, particularly if it hasn’t received regular maintenance. Consider whether recurring issues are a sign that it’s time to upgrade to a newer, more energy-efficient model.
