Reduced Cooling Capacity Due to Condenser Fouling
Likely causes
Dust, grease, or lint accumulation
Check: Disconnect power and remove condenser cover
What to do: Disconnect power and remove condenser cover → Blow dust with compressed air (against airflow direction) → For heavy grease: apply alkaline cleaner, then rinse → Straighten bent fins with a fin comb → Measure high-side pressure after restart to confirm improvement
Hot air recirculation from insufficient clearance
Check: Blow dust with compressed air (against airflow direction)
What to do: Blow dust with compressed air (against airflow direction) → For heavy grease: apply alkaline cleaner, then rinse → Straighten bent fins with a fin comb → Measure high-side pressure after restart to confirm improvement
Long-term maintenance neglect
Check: For heavy grease: apply alkaline cleaner, then rinse
What to do: For heavy grease: apply alkaline cleaner, then rinse → Straighten bent fins with a fin comb → Measure high-side pressure after restart to confirm improvement
The condenser coil/fin is fouled, causing poor heat rejection. Cleaning will provide immediate improvement. Do not spray cleaning agents directly on electrical components.
