Drink door switch faults

Drink machines rely on refrigeration performance, column alignment, and strong door seals. Electrical or cooling issues often present as temperature drift. Handle door switch service errors.

• Check door gasket seal and condenser cleanliness.
• Verify temperature sensor readings and controller setpoints.
• Inspect stack/column alignment for mis-vends.

• Clean condenser coils and ensure airflow clearance.
• Replace faulty temp probes or relays.
• Align columns and adjust shims for product fit.

• Vacuum coils monthly in dusty locations.
• Log temperature readings by location.
• Rotate stock to reduce heat load.

• Issues persist after a controlled test and documented settings.
• Errors repeat across multiple machines or locations.
• You need replacement parts or manufacturer diagnostics.
