How to Reset Mitsubishi Air Conditioner in 4 Easy Steps

Just like any other electronic appliance, you might be asking how to reset your Mitsubishi air conditioner. This action is needed after a power outage in particular.

A reset is required when the air conditioner happens only to blow the warm air even though it’s set to cool mode already.

The Mitsubishi AC unit seamlessly integrates with the home’s HVAC system to provide efficient and consistent temperature control.

Some companies build their unit more innovatively, while others still hold the old-fashioned reset system. Typically, it’s such an easy task as you only need to push the reset button to remove all the power in the unit.

Step 2: Power down the breaker

Start by locating your circuit breaker or reset button on your Mitsubishi air conditioner that is connected to the outside unit. Most Mitsubishi air conditioner comes with this reset button.

If you have a hard time finding the button, try opening the circuit breaker box to help you detect the breaker position. These reset buttons appear in small sizes with red color. You may also need a user’s guide manual book for a quick reference.

Once you find them, you can switch the breaker off by pushing them from 3 to 5 seconds. Then the power will be removed from the air conditioner.

Step 3: Hang On for 30 Seconds

Mitsubishi air conditioner is not built to immediately reset the internal circuit breaker even though the outside breaker is in off mode.

You should wait for about 30 seconds to allow the inside breaker to reset itself completely. After that, you’re able to turn it back on.

Step 4: Turn The Unit Back On

Lastly, you can turn the unit back on by pressing the power button on your remote or thermostat. Your air conditioner is now fully restored.

In this step, you may check the settings on the remote based on your likings.

Call The Technician
