How to Reset Air Conditioner?

To reset an air conditioner, start by powering it down by flipping the breaker that powers it and turning off the power switch connected to it outside.

Next, locate the reset button, typically red and small, and hold it down for 3 to 5 seconds before releasing.

After that, restore power by flipping all switches, including the one in the breaker panel, to the “on” position.

Set the thermostat to “cool” and a lower temperature than the current temperature inside the home.

Finally, cold air should start blowing through the vents, indicating a successful reset.

If the reset button does not work, it is best to contact an HVAC professional for assistance.

Key Points:

  • Power down the air conditioner by flipping the breaker and turning off the power switch
  • Locate and hold down the reset button for 3 to 5 seconds
  • Restore power by flipping all switches to “on”
  • Set the thermostat to “cool” and lower the temperature
  • Cold air should start blowing through the vents
  • Contact an HVAC professional if the reset button doesn’t work

Did You Know?

1. The first air conditioner was not invented for the purpose of cooling the air, but rather to control humidity in a printing company. It was invented by Willis Carrier in 1902 and was called the “Apparatus for Treating Air.”
2. Many people believe that turning down the thermostat of an air conditioner will cool the room faster, but this is actually a myth. Air conditioners cool a room at a fixed rate, regardless of the temperature setting.
3. The world’s largest air conditioner can be found in the United Arab Emirates. Located in the Sheikh Zayed Grand Mosque, this massive air conditioning system covers an area of 16,500 square meters (approximately 177,600 square feet).
4. In some cases, resetting an air conditioner can be as simple as turning off the power for a few minutes and then turning it back on. This allows the internal components to reset, solving minor issues without the need for professional assistance.
5. Air conditioners can negatively affect your sleep patterns. The cool temperature they create can lead to a decrease in the production of melatonin, a hormone that regulates sleep. To mitigate this, it’s recommended to set the air conditioner to a slightly higher temperature or use a fan in combination with the air conditioner to maintain airflow.

Common Reasons For An AC Requiring A Reset

One common reason for an air conditioner to require a reset is when the protection circuit breaker is triggered after a power outage. This safety mechanism is important as it cuts off power to the AC unit to prevent fires and explosions. However, the sudden loss and restoration of power can sometimes cause the AC to malfunction, leading to problems like the unit only blowing warm air.

The Role of the Protection Circuit Breaker

During a power outage, the protection circuit breaker senses the imbalance in the electrical current and automatically shuts off the power supply. This helps to safeguard the AC unit and the surrounding area from potential electrical dangers. However, when the power is restored, the AC may not automatically resume normal functioning, requiring a reset to bring it back to proper operation.

  • It automatically shuts off the power supply during a power outage
  • This safeguards the AC unit and surrounding area from potential electrical dangers
  • After power is restored, the AC may not resume normal functioning automatically
  • A reset is required to bring it back to proper operation.

Is there a reset button on an air conditioner?

Yes, air conditioners generally have a reset button, which is usually red and easily visible on the exterior of the machine. It is most commonly found around the bottom edge of the unit, near the ground. However, if you are unable to locate the reset button on the outside, it may be concealed within the unit behind the service panel. Remember to consult the AC’s manual or contact a professional if you’re having trouble finding or resetting the button, as mishandling it can cause further damage to the unit.

Why is my AC running but not cooling?

If your AC is running but not cooling, it could indicate that the condenser coil is blocked or clogged. The condenser fan is responsible for drawing air into the unit through the coil to remove heat from your home. However, if the coil is blocked, the air flow is obstructed, preventing efficient cooling. It is important to clean or clear the condenser coil regularly to ensure proper airflow and optimal cooling performance.

How long does it take for AC to reset?

The resetting process of an air conditioner typically requires around 30 minutes. During this time, the internal circuitry adjusts and readies itself to resume functioning. It is advisable to patiently wait for this duration before turning on the air conditioner again using the thermostat. Once the 30 minutes have elapsed, you can safely activate the unit and enjoy the cool air it provides.
