How to Reset A Portable Air Conditioner?

It is recommended to reset a portable air conditioner if it is not working properly. You can reset your air conditioner by unplugging the switch and plugging it back again.

If the portable air conditioner does not work after resetting it by unplugging it, call a professional technician to identify the issue.

However, there are a few steps to restart / troubleshoot your portable air conditioner at home:

Step 1: Turn off the power button and unplug the switch of the air conditioner. You need to unplug the switch before resetting the air conditioner to ensure there is no flow of electricity in the air conditioner to avoid any damage to you or the air conditioner.

Step 2: After unplugging the switch, wait for a few minutes to let the components of the air conditioner cool down. The in-built feature of the air conditioner does not allow its components to cool down immediately after turning off.

It will help the components to cool down gradually according to their specifications.

Step 3: While parts of the air conditioner are cooling down, you can check the filters. A clogged filter can hinder the cooling and damage the capacity of the unit.

Firstly, remove the filters and check if there is any dust or dirt on them. Clean the filters with a warm wet soft cloth and dry them for a while.

Attach the filter again to the air conditioner and restart it to check its function. If the filters are damaged or twisted, replace them immediately.

Step 4: After giving rest to the components of the air conditioner for a few minutes and cleaning/replacing the filters, plug in the unit of the air conditioner back and turn the button on. Make sure the unit is plugged in properly.

Step 5: If there is a reset button on your air conditioner, hold it for a while and wait until an indicator flashlight turns on. If you can not find the reset button, consult the user manual.

By resetting the air conditioner the setting will automatically be set to default so you can fix it according to your need.

If there is no reset button, you can unplug the unit for a longer period, such as 25-30 minutes. If you feel any issues after restarting the system, you can contact a professional technician for this.
