What Does Error P3 Mean?
The P3 error code on your Kelvinator air conditioner indicates that the unit is in a compressor medium frequency test mode, which may signal a compressor overload. This error is often associated with unusual buzzing sounds and intermittent cooling. If you see the P3 code on your remote or unit display, it is essential to check the unit's state and perform a power reset to determine if the issue resolves.
Common Symptoms:
