High Pressure Rise from Condenser Fouling
Likely causes
Dust, grease, or lint accumulated on fins
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 grease: apply alkaline cleaner then rinse → Straighten bent fins with fin comb → Confirm high-side pressure normalizes after restart
Long-term maintenance neglect
Check: Blow dust with compressed air against airflow direction
What to do: Blow dust with compressed air against airflow direction → For grease: apply alkaline cleaner then rinse → Straighten bent fins with fin comb → Confirm high-side pressure normalizes after restart
Cleaning the condenser will immediately reduce high-side pressure. Establish a regular cleaning schedule.
