How to Reset Your Fujitsu Mini-Split (2025 Guide) — And What to Look Out For

If your Fujitsu mini-split air conditioner suddenly stops cooling properly or starts acting up, a quick reset can often bring it back to life. Whether it’s after a power outage or you’re noticing strange behavior, resetting your system can clear minor issues and save you a technician visit.

In this 2025 guide, we’ll walk you through when and how to reset your Fujitsu mini-split, what problems it can fix, and how to keep your Fujitsu mini-split running smoothly with a smart controller like Klima Smart Thermostat.

When Should You Reset Your Fujitsu Mini-Split?

Your Fujitsu mini-split might need a reset if it’s behaving differently than usual. A quick reset can fix common issues like these:

1. Tripped Circuit Breaker

If your system isn’t turning on at all, check your home’s breaker panel. After flipping the switch back on, reset your mini-split to restore operation.

2. Inconsistent Cooling

Not getting the cooling you expect? A reset can help your mini-split recalibrate its sensors and settings.

3. Blowing Hot Air

If the unit is blowing warm air when it should be cooling, a simple reset can often fix the mode settings.

4. Turning On and Off Frequently

Short cycling (rapidly turning on and off) can stress your system and waste energy. A reset may stabilize its operation.

5. Strange Noises

Buzzing or clicking sounds can sometimes be the result of minor electronic glitches. Try resetting before calling a technician.

6. High Humidity

If the air feels damp and your Fujitsu isn’t dehumidifying properly, a reset may help restore balance.

7. Not Powering On

If the indoor unit isn’t responding, a reset is an easy first troubleshooting step.

How to Reset Your Fujitsu Mini-Split

Resetting a Fujitsu mini-split is simple and takes just a few moments — but do it carefully.

Step 1: Find Your Remote Control

Locate your Fujitsu remote. At the bottom, you’ll see a small RESET button.

Step 2: Press the RESET Button

Using a small, blunt object like a paperclip, gently press the RESET button.
Be careful not to use anything sharp or apply too much force — this can damage the button.

Step 3: Reset the Filter Lamp (Optional)

Fujitsu mini-splits have a filter indicator lamp that lights up when your filters need cleaning.
After cleaning them, press the RESET button next to the lamp to clear the alert.
This step keeps your mini-split running efficiently and helps maintain good air quality.
