How to Reset a Daikin Mini-Split in 2026

Resetting a Daikin mini-split clears error codes and temporary faults that can leave the unit in a locked-out state. Daikin offers three reset methods: a circuit breaker reset (most effective), a remote control reset, and in some models, a reset button on the indoor unit. This guide covers all three with exact steps.

Method 1: Circuit Breaker Reset (Recommended)

Step 1: Turn the unit off using the remote (press ON/OFF).
Step 2: Go to your electrical panel and switch off the dedicated breaker for the Daikin unit.
Step 3: Wait 30 seconds minimum. For persistent error codes, wait 5 minutes.
Step 4: Switch the breaker back on.
Step 5: Wait 3 full minutes before operating. Daikin compressors have a built-in protection delay after power restoration — pressing buttons during this window resets the timer.
Step 6: Turn on with the remote and verify normal operation.

Method 2: Remote Control Reset

The Daikin wireless remote has a small RESET button — a recessed pinhole typically on the back panel or bottom edge of the remote.

Step 1: Using a thin pin or pen tip, press and hold the RESET button for 3 seconds.
Step 2: The remote display will blank and restart.
Step 3: Re-enter your temperature and mode preferences.

Note: This resets the remote's memory only — not the indoor unit's fault log. Use the breaker method to clear error codes from the unit.

Frequently Asked Questions

My Daikin won't turn on after a reset — what's wrong?

The 3-minute compressor protection timer is the most common reason. After any power interruption, Daikin systems delay compressor startup by 3 minutes to protect the compressor from short-cycling. Wait the full 3 minutes before pressing any buttons. If the unit still will not turn on after 3 minutes, check for an active error code on the indoor unit's indicator light.

Does resetting my Daikin void the warranty?

No. A standard breaker reset is a normal user operation and does not affect Daikin's warranty coverage.
