If you’re faced with a Minisplit that is flashing an error code at you and you’re unsure how to determine what the code is or what to do here’s how to tell if it’s actually normal flashing.
Right now with the cold winter temperatures and the freezing rain and snow and sleet and driving winds that we have been receiving here in our area it’s been putting a tremendous amount of stress on the heat pumps as they try to produce heat for your home because the outdoor condensing unit is located outside and in some cases is not protected from these types of elements.
Above is a good example of an install that is protected from the home yet is still far enough away from the house to allow for proper airflow behind the machine which is wheddsd
If you have only one single flashing light at you and it is steady and constant this might be a defrost mode.
Defrost mode occurs as part of normal operation when the coil outside gets too cold the outdoor condensing unit stops and send a signal inside to have the fan slow down sometimes the fins will close up and the light will start the flash to indicate the unit is in defrost mode outside this might be in the state for 6-8 minutes.
During the 24 hour period you may not notice but the unit could do this maybe four times a day or more.
