How to Reset Friedrich Outdoor Unit: A Comprehensive Guide

In this comprehensive guide, we’ll delve into the step-by-step process of resetting a Friedrich outdoor unit, providing you with the technical expertise and hands-on approach to ensure your air conditioning system is functioning at its best.

Locating the Reset Button

The reset button on a Friedrich outdoor unit is typically located near the power cord of the unit. It may be a small red button or a larger button with the word “Reset” printed on it. To locate the reset button, you’ll need to carefully inspect the exterior of the unit, paying close attention to the areas around the power cord and control panel.

It’s important to note that the exact location of the reset button may vary depending on the specific model of your Friedrich outdoor unit. Consult your user manual or contact Friedrich customer support for more detailed information on the location of the reset button for your particular model.

Preparing the Unit for Reset

Before attempting to reset the Friedrich outdoor unit, it’s crucial to ensure that the unit is turned off. You can do this by pressing the power button on the control panel or by unplugging the unit from the wall outlet. This step is essential to prevent any potential damage or interference during the reset process.

Resetting the Unit

Once you’ve located the reset button and turned off the unit, it’s time to initiate the reset process. Follow these steps carefully:

  1. Press and Hold the Reset Button: Locate the reset button and press and hold it for approximately 5 seconds. This duration is crucial to ensure that the reset process is properly initiated.
  2. Monitor the Unit’s Response: As you hold the reset button, observe the unit’s behavior. You may notice the unit’s display or indicator lights flashing or changing, indicating that the reset process is underway.
  3. Release the Reset Button: After holding the button for 5 seconds, release the reset button. This should trigger the unit to begin its reset sequence.
  4. Wait for the Unit to Cycle On: After releasing the reset button, wait patiently for the unit to cycle on and resume normal operation. This process may take a few minutes, so be patient and allow the unit to complete its reset cycle.

Verifying the Reset

Once the unit has cycled on, it’s essential to verify that the reset was successful. Check the unit’s display or control panel for any error codes or indicators that may suggest the reset was not effective. If the unit is operating normally and any previously displayed error codes have been cleared, the reset was successful.

Troubleshooting the Reset Process

If the reset button does not work or if the unit still does not operate properly after the reset, there are a few additional steps you can take:

  1. Consult the User Manual: Refer to the user manual for your specific Friedrich outdoor unit model. The manual may provide additional guidance or troubleshooting steps specific to your unit.
  2. Contact Friedrich Customer Support: If the reset process is still not working or you’re unsure of the next steps, reach out to Friedrich customer support. Their team of experts can provide personalized assistance and guidance to help you resolve the issue.
  3. Check for Power Supply Issues: Ensure that the unit is receiving the proper power supply. Verify that the circuit breaker is not tripped and that the power outlet is functioning correctly.
  4. Inspect for Physical Damage: Carefully inspect the unit for any visible signs of physical damage, such as cracks, dents, or loose connections. If you notice any damage, it’s best to contact a professional HVAC technician for further assistance.

Additional Considerations

In some cases, the reset procedure may vary depending on the specific model or issue with the unit. For example, to reset the check filter alert on newer Friedrich Wallmasters models without a Check Filter button on the control panel, you can follow these steps:

  1. Use the Unit for 250 Hours: After 250 hours of use, the CHECK FILTER light will come on.
  2. Press and Hold the Fan and Speed Buttons: Press and hold the Fan and Speed buttons together for 5 seconds to reset the alert.

This procedure is not documented in the instruction manual, but it was confirmed by a Friedrich customer support representative.

Remember, it’s always a good idea to consult the user manual or contact Friedrich customer support if you’re unsure about any aspect of the reset process or if you encounter any issues with your outdoor unit.


Resetting a Friedrich outdoor unit can be a straightforward process, but it’s essential to follow the proper steps to ensure the safety and effectiveness of the reset. By carefully locating the reset button, preparing the unit, and executing the reset procedure, you can help maintain the optimal performance of your air conditioning system.

If you encounter any difficulties or have additional questions, don’t hesitate to reach out to Friedrich customer support or consult the user manual for your specific model. With this comprehensive guide, you’ll be well-equipped to handle the reset process and keep your Friedrich outdoor unit running smoothly.
