What daily or weekly cleaning is necessary to maintain airflow?

Airflow failures in summer are often simple maintenance issues. A practical routine is:

Daily (or every shift in flour-heavy kitchens):

Wipe down and keep the front and rear grilles clear of dust, labels, and splash.

Check that no packaging or GN pans are blocking internal fan vents or air returns.

Weekly:

Remove the accessible grille and vacuum the condenser area carefully (soft brush attachment helps). If grease is present, use a suitable degreaser and let everything dry before refitting.

Inspect door gaskets for splits and debris, and clean the seal channel so the door closes firmly.

After cleaning:

Confirm the unit is not pushed back so far that it crushes the air gap or kinks cables.

If the condenser is heavily greased or inaccessible, plan a periodic deeper clean with a competent technician to avoid repeated overheating and compressor strain.
