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:

  • P3 displayed on unit or remote control indicating a specific condition code rather than a generic fault

Possible Causes

  • Compressor operating in medium frequency test/diagnostic state (medium)
  • AC input overcurrent protection triggered (low)

How to Fix Error P3

DIY Fix Check unit state and reset power

  1. Turn the air conditioner off using the remote or power switch
  2. Disconnect the air conditioner from mains power (isolate power) for 10–15 minutes
  3. Reconnect and restart the unit to see if the P3 code clears

Technician Only Inspect compressor operation and current draw
