Comfort-Aire Mini Split troubleshooting guide
Mini-splits can be an ideal solution for cooling and heating your home. They are not only far more energy-efficient than window units but also create zoned comfort. While there are many brands in the market, Comfort-Aire mini-split units have been around for years and are very popular with users. Affordably priced and energy-efficient, Comfort-Aire mini-split units last a long time.
However, like any other electrical appliance, they may develop an issue once in a while.
In this post, we will discuss some of the common issues with Comfort-Aire mini-split units and their solutions.
How to Resolve the Error Code E1?
The error code E1 pertains to the air filter. In most cases, it is a reminder that your air filter needs cleaning. Once you have cleaned it, perform the steps below to reset it.
- Switch off your Comfort-Aire mini split unit by pressing the “power” button
- Now unplug your unit from your wall socket
- Holding the “power” button on your front panel, plug in the mini split air conditioning unit. You must continue holding the power button as your air conditioner performs a small test sequence. As soon as the test sequence ends, you will hear a short “beep” sound. This is the cue for you to release your power button
- Now unplug the unit again
- Plug it back once more
That’s it. Now when you use the air conditioner you should not get the E1 error code.
If this solution doesn’t work, we recommend you give the following steps a try. Many users were able to fix this error through the following method.
- Unplug the mini split AC for about 5 seconds
- Plug it back and hold the power button till you hear a beep
- Pull out the power plug and reconnect it
- Press the “Mode” button while the unit starts. Don’t let go of the “Mode” button till there is a beep sound and the unit starts operating
- Release the “Mode” button and press the Power button on your front panel to turn the air conditioner off
- Press the Power button to turn on the unit
If neither of the two solutions works, you should contact a local AC repair expert to resolve the problem.
