Did You Know?
1. In 1930, engineer Ralph H. Cameron invented the first automatic thermostat to regulate air conditioning. This invention marked a significant advancement in temperature control technology.
2. Did you know that resetting an AC thermostat can sometimes help improve its energy efficiency? By resetting the thermostat to a slightly higher temperature, the AC unit won’t have to work as hard to cool the room and can save you money on your energy bills.
3. The first air conditioning system for a private home was installed in 1914 in the mansion of Charles Gates, the founder of the Gates Rubber Company. This early system required a considerable amount of space and generated quite a bit of noise compared to modern AC units.
4. The ideal temperature to set an AC thermostat for energy efficiency and comfort is generally considered to be around 78°F (25.5°C) during the summer months. This temperature allows the AC unit to work efficiently while keeping you cool without unnecessarily overcooling the room.
5. When resetting your AC thermostat, be mindful of potential power surges. If you reset the thermostat immediately after a power outage, there may be a sudden influx of electricity when the power is restored, which could potentially damage the system. It’s best to wait a few minutes before resetting the thermostat to ensure a more stable electrical supply.
1. Shutting Down The AC Unit At The Thermostat
To reset a malfunctioning AC thermostat, start by shutting down the AC unit at the thermostat and turning it to the “off” position. This will stop the unit from running and initiate a complete reset. By giving the system a chance to recalibrate its settings, this step can potentially resolve any issues it may be experiencing.
Although this step may appear simple, it is a crucial part of the reset process. By turning off the AC unit at the thermostat, you are essentially cutting off power to the system, allowing it to reset itself. This action is comparable to rebooting a computer to address software glitches.
2. Flipping The Circuit Breaker To The “Off” Position
To ensure a complete shutdown of your AC unit, in addition to turning off the thermostat, it is important to find the circuit breaker box and switch off the breaker specifically assigned to the AC unit. The circuit breaker functions as a safety device, safeguarding the electrical circuits against overloads and short circuits. By switching it to the “off” position, you effectively cut off all power supply to the AC unit, enabling a reset.
To locate the circuit breaker box, check for a metal box usually situated in the basement, utility room, or garage. Inside the box, you will find several circuit breakers labeled for different areas of your home. Locate the corresponding breaker for your AC unit and switch it off. This ensures that no electrical current is being supplied to the unit during the reset process.
3. Waiting For 30 Seconds
After shutting down the AC unit at the thermostat and flipping the circuit breaker to the “off” position, it is crucial to wait for at least 30 seconds before proceeding. This waiting period allows time for any residual electrical charge in the system to dissipate.
Waiting for 30 seconds is important because it gives the AC unit enough time to reset and discharge any lingering power that may be causing the malfunction. This brief pause also gives the system a chance to cool down and stabilize before it is turned back on.
4. Moving The Thermostat Back To The “On” Position
Once the waiting period is over, you can proceed to move the thermostat back to the “on” position. This step will reactivate the AC unit and initiate the reset process. By moving the thermostat back to the “on” position, you are instructing the system to resume normal operations.
The AC unit should start up once the thermostat is moved back to the “on” position and begin cooling the air. It may take a few minutes for the system to reach the desired temperature, so be patient during this process.
- Move the thermostat back to the “on” position to reactivate the AC unit.
- Be patient during the cooling process.
5. Calling For Professional Help If AC Unit Still Doesn’t Work
If, after following the previous steps, your AC unit still does not work properly, it is advisable to call for professional help. AC units may require a reset after a power outage or when there are issues such as the unit blowing warm air. The reset is important to prevent the risk of fires and explosions.
Contacting an HVAC professional is recommended because they can diagnose the underlying issue and provide the appropriate solution. They have the knowledge and experience to identify and fix complex problems that may be affecting your AC unit. Additionally, professionals may be able to perform a more thorough reset that involves checking the electrical connections, sensors, and other components of the system.
- If your AC unit is not working properly after following previous steps, it is advisable to call for professional help.
- AC units may require a reset after a power outage or when facing issues like blowing warm air.
- Resetting the unit is important to avoid the risk of fires and explosions.
- Contacting an HVAC professional is recommended as they have the necessary expertise to diagnose and solve your AC unit problems.
- Professionals can perform a more thorough reset that involves checking electrical connections, sensors, and other components.
Note: It is always better to consult professionals for proper maintenance and repair of your AC unit.
6. Additional Reset Techniques For Window AC Units
If you have a window AC unit and the reset button on the thermostat does not work, there are additional techniques you can try:
- Unplug the unit and wait a few minutes before plugging it back in. This can help reset the settings and resolve any minor issues.
However, if the problem persists or is more severe, it is still recommended to contact an HVAC professional. They will have the specialized knowledge and tools necessary to diagnose and fix the problem with your window AC unit.
Remember to shut down the AC unit at the thermostat, flip the circuit breaker to the “off” position, wait for 30 seconds, move the thermostat back to the “on” position, and call for professional help if necessary.
For window AC units, unplugging and waiting a few minutes before plugging it back in can serve as an alternative reset technique.

Frequently Asked Questions
How do I reset my air conditioner thermostat?
To reset your air conditioner thermostat, begin by shutting down your AC at the thermostat. This can be done by turning it off at the AC unit. Next, locate your circuit breaker box and reset the circuit breaker specifically meant for your AC unit. After resetting the circuit breaker, wait for about 30 seconds before turning the AC thermostat back on. This process should reset your air conditioner thermostat and restore its normal function.
How do I manually reset my AC unit?
To manually reset your AC unit, begin by locating the reset switch, usually a small red button on the outdoor unit. If you are having trouble finding it, consult the manufacturer’s manual for guidance. Press and hold the red button for approximately three seconds, then release. This action should reset the AC unit and resolve any issues you may be experiencing.
Can resetting thermostat fix AC?
Resetting the thermostat can indeed fix certain issues with an AC. When a power outage occurs, the AC’s safety mechanisms may be triggered, causing it to go into a protective mode that prevents any potential fires or explosions. By resetting the thermostat, you can clear these safety settings and allow the AC to function normally again. Additionally, a reset can correct a situation where the AC is blowing warm air despite the thermostat being set to “cool.” In some cases, this could be due to a general thermostat error, and resetting it can help resolve the issue and restore cool air circulation.
Why is my AC thermostat not cooling?
If your AC thermostat is not cooling, there could be several potential reasons. Firstly, it is possible that the air conditioning unit itself is malfunctioning and not properly cooling the air. Additionally, if your thermostat is set to the wrong temperature or the temperature sensor within the thermostat is not working correctly, this can also lead to a lack of cool air. It is recommended to check both the air conditioning unit and the thermostat settings to ensure they are functioning properly. If the issue persists, it is best to contact professional assistance to diagnose and address any potential problems with the system.
