Timer/Check Indicator Lamp (Yellow) Long Flash — Filter cleaning required

What does Timer/Check Indicator Lamp (Yellow) Long Flash mean?

The yellow Timer/Check indicator lamp flashes with a long pattern (2 seconds on, 1 second off). This indicates that the air filter needs cleaning, typically occurring after approximately 120 hours of cumulative operation. A clogged filter can lead to reduced cooling/heating capacity, increased noise, and potential dew formation.
