Rheem Air Conditioner: Locating and Using the Reset Button

Rheem air conditioners are known for their reliability and efficiency in providing cooling solutions for homes and businesses. However, like any electronic appliance, they may occasionally experience technical issues. One of the most straightforward ways to address minor problems is by using the reset button. This article offers a comprehensive guide on locating and effectively utilizing the reset button on your Rheem air conditioner.

Understanding the Purpose of the Reset Button:

The reset button on a Rheem air conditioner serves as a quick-fix solution for various operational issues. It can help resolve problems like unresponsive controls, system errors, or the air conditioner failing to start. The reset process can often clear these issues, restoring the unit to its normal function without the need for professional intervention.

Locating the Reset Button:

  1. Safety Precautions: Ensure your safety by turning off the power supply to your Rheem air conditioner before attempting any maintenance tasks. This can be done at the circuit breaker or power outlet.
  2. Finding the Button: The reset button on a Rheem air conditioner is usually located on the outdoor unit. It’s typically a red or yellow button, situated in an easily accessible area. You may need to remove an access panel or cover to locate it.

Steps to Reset Your Rheem Air Conditioner:

  1. Press the Reset Button: Once you have located the reset button, press and hold it for a few seconds. You might hear a clicking sound, indicating that the unit is resetting.
  2. Restore Power: After pressing the reset button, turn the power back on to the unit.
  3. Check the Air Conditioner: Turn on the air conditioner and observe its operation. It should start normally, and you should notice the return of regular cooling functions.

Post-Reset Troubleshooting:

  • Persistent Issues: If the air conditioner continues to experience the same issues after resetting, it might indicate a more serious problem that requires professional attention.
  • Regular Maintenance: To avoid frequent resets, ensure regular maintenance of your air conditioner. This includes cleaning filters, checking refrigerant levels, and ensuring the outdoor unit is free from debris.

When to Seek Professional Assistance:

  • Complex Issues: If resetting doesn’t resolve the problem, or if you’re uncomfortable performing these steps, it’s advisable to seek help from a qualified HVAC technician. They can provide a thorough diagnosis and resolve more complex issues.
  • Routine Professional Maintenance: Scheduling regular professional maintenance can prevent many common issues and extend the lifespan of your Rheem air conditioner.


Resetting your Rheem air conditioner is a simple yet effective way to troubleshoot and resolve minor issues. By following these steps, you can ensure your unit returns to optimal functioning without the immediate need for professional intervention. However, it’s important to recognize when an issue extends beyond a basic reset. Regular maintenance, both DIY and professional, is essential for the longevity and efficiency of your Rheem air conditioner. Staying proactive about maintenance and being aware of how and when to use the reset button can help maintain a comfortable and cool environment in your home or business. In cases where problems persist or you’re unsure about tackling them yourself, don’t hesitate to call in a professional. Proper care and attention will keep your Rheem air conditioning system running smoothly for years to come.
