Troubleshoot error code “H3” in Ferroli air-conditioning

  • Error: “H3”
  • Description: Compressor overload protection
  • Cause: The compressor is working more than it should
  • Solution: Inspection and possibly calling Technical Support

When your Ferroli air conditioner starts flashing a mysterious “H3” on the screen, it’s normal to feel a bit confused. But don’t worry, here at codigodeerror.com, we’ll explain what it means and how you can fix it.

What is the compressor, and why is it overloaded?

The compressor is the heart of your air conditioner; it moves the refrigerant through the system to cool your home. If the compressor is overloaded, it may be due to various reasons, such as insufficient refrigerant or a dirty filter causing it to work harder than normal.

Steps to Resolve Error “H3”

1. Turn off and on the equipment

  • Sometimes, a simple restart can solve the problem. Turn off the air conditioner from the main switch, wait a few minutes, and turn it back on.

2. Check the filters

  • A dirty filter can cause the compressor to strain. Ensure the filters are clean, and if necessary, clean or replace them.

3. Inspect the airflow

  • Ensure that air outlets and inlets are not blocked. Restricted airflow can increase the load on the compressor.

4. Verify the refrigerant

  • If you have technical knowledge, you can check if the refrigerant level is adequate. However, if you’re unsure how to do it, it’s better to contact a professional.

5. Call Technical Support

  • If after these checks the “H3” code persists, you likely need the assistance of a specialized technician. They can accurately diagnose and fix the problem.

When to Call a Professional?

If you’re not comfortable performing these checks yourself or if the problem persists after trying the above solutions, it’s time to call a technician. They have the tools and experience to resolve the issue without jeopardizing your equipment.

Tips to Prevent Future “H3” Errors

  • Regular maintenance: Perform periodic maintenance on your air conditioner to ensure everything is working correctly.
  • Filter cleaning: Clean or replace filters regularly to prevent dirt buildup.
  • Proper usage: Avoid overloading the air conditioner by setting the temperature too low on extremely hot days.

Remember that good maintenance not only prevents errors like “H3” but also extends the lifespan of your air conditioner and helps you save energy. Take care of your air conditioner, and it will take care of you!
