How to reset Mitsubishi Air Conditioner Step by Step

Step 1. Shut down the indoor unit. 

For starting the process, simply you have to shut down the power button as you normally do. 

Step 2. Turn off the breaker.

Locate and switch off the Mitsubishi air conditioner unit’s breaker. If you are facing any difficulty in finding it then simply open the circuit breaker box and look for a circuit with the air conditioning label.

If you are unable to find it then search for the switch in the neutral position and make sure to turn it off.

Step 3. Hold on for 30 seconds. 

You have to wait for approximately 30 seconds to fully reset in the given duration. As the Mitsubishi air conditioner does not reset immediately. To protect itself from malfunctioning, the system may require additional time to recover from a power outage. In this type of situation, it’s better to wait for up to a minute. 

Step 4. Turn on the breaker.

You can turn on the breaker again after waiting for 30 seconds.

Step 5. Switch on the Remote/Thermostat.

Wait! No lights are on (on the indoor unit)

After turning on the air conditioner if no indicator lights are on then it means you might have blown a fuse on the air conditioner during the reset process. 

It’s better to call a technician first before attempting the replacement of the fuse by yourself. The technician may install an inline fuse holder for your convenience so you easily replace it in case the fuse blows again. 

It’s important to note that in some cases the indoor indicator light may be on first yet, even after a three-minute interval, the outdoor unit may still not initiate. In this case, it’s better to call a professional technician to repair the fuse of your air conditioner.
