The fresh air control panel is an essential component of the fresh air system, responsible for controlling its operation. A malfunctioning control panel will prevent the system from running properly, thereby affecting indoor air quality.

There are several reasons why a control panel might stop working, primarily including:

● Power Failure: This is the most common cause. It may be due to broken power cords, poor socket contact, or a damaged power switch.

● Controller Malfunction: The controller is the core of the panel. Issues here—such as damaged components or software glitches—can lead to total failure.

● Sensor Failure: Panels are usually equipped with sensors to detect air quality. If these sensors fail due to component damage or signal interference, the panel may stop functioning.

● Software Faults: Faults in the control program, such as coding errors or data corruption, can prevent the panel from operating normally.

● Other Causes: These include mechanical failures or external electromagnetic interference.

If the control panel is not working, you can troubleshoot using the following steps:

● Check if the power supply is normal.

● Inspect the controller for damage.

● Test if the sensors are functioning.

● Verify if there is a software glitch.

● Check for any mechanical obstructions.

If the cause remains unidentified, please contact professional maintenance personnel.

Here are some suggestions to extend the lifespan of your fresh air control panel:

● Avoid using the panel in damp or humid environments.

● Avoid environments with strong electromagnetic interference.

● Clean the control panel regularly.

● Replace damaged components promptly.

Ensuring the fresh air system works correctly is vital for indoor air quality. Regular inspections are key to a healthy home environment.
