Outdoor unit keeps running [air conditioner]
As hot air expands, it gets lighter and moves upward, when it gets cold, it contracts and thus becomes heavier and moves downward.
For this reason, the air at the top area where a wall mounted type air conditioner head unit is mounted is rather hot but the air in the space underneath where customers move about is usually colder.
Cause and Symptom
- Different measurements from the remote controller sensor and the indoor unit’s cause both outside and inside units to continually operate.
Try this
The sensor that detects the indoor temperature is mounted in the indoor unit thus ending up measuring relatively hot air at the top, while the temperature difference with respect to the ground floor can be in the vicinity range of 1°~3° in Celsius (2°~6° in Fahrenheit).
The indoor temperature displayed on the remote controller (lower ground temperature) differs from the temperature measured from the air conditioner head unit’s sensor (ceiling temperature).
The indoor temperature displayed on the remote controller is measured where the remote controller is located at that time, and it can differ from the temperature measured from the air conditioner unit.
As the cold air fills up the ceiling area to make the temperature distribution more even, the air conditioner knows that the target temperature is reached and the outdoor unit will operate at minimum level, so that the indoor temperature does not drop any further.
