Daikin AC Remote Not Working? 7 Fixes That Actually Work India (2026)

Your Daikin AC stopped responding to the remote in the middle of summer. Before calling a ₹500–1500 technician — try these 7 fixes. Most Daikin remote problems are solved in under 5 minutes.

Fix 1 — Check LOCK Mode First

Look at your Daikin remote display. If you see a padlock icon, the remote is locked. Press and hold the CANCEL button for 5 seconds to unlock. This solves 30% of all Daikin remote complaints — especially from kids accidentally activating it.

Fix 2 — Replace Batteries

Remove and replace both AAA batteries with fresh ones. Even batteries showing charge may not power the IR LED properly. Heavy summer AC use drains batteries faster than expected.

Fix 3 — Phone Camera IR Test

Open your phone camera. Point the Daikin remote at the lens. Press any button. White or purple flash visible on screen = IR is working (problem is the AC unit's IR receiver). No flash at all = remote IR is dead = needs replacement.

Fix 4 — Check for Sunlight Interference

Direct sunlight on the AC indoor unit's IR sensor window blocks the remote signal completely. Close curtains or blinds on south-facing windows and test again. Common in Indian summer afternoons.

Fix 5 — Clean the IR Sensor

The IR receiver window on your Daikin indoor unit (small clear plastic area at the bottom front) may be dusty. Wipe gently with a dry soft cloth and test the remote.

Fix 6 — Power Cycle the AC

Switch off the AC at the MCB/circuit breaker. Wait 5 minutes. Switch back on. This clears software freezes from continuous summer operation. Then test the remote.

Fix 7 — Reset the Remote

Remove batteries. Press and hold the Power button for 20 seconds to discharge residual power. Reinsert fresh batteries. Test again.

When to Replace the Remote

If all 7 fixes fail, the remote needs replacement. Check the ARC code on the back of your existing Daikin remote and order the correct model from Faritha.com.
