Initial Complaint — Cooler Not Maintaining Proper Temperature

What started as a basic cooling issue turned out to be a much deeper problem. At AF Appliance, we often find that commercial refrigeration failures don’t come from just one part but from multiple small issues building up over time.

Why Commercial Coolers Often Lose Efficiency

Commercial refrigeration units work continuously, and even minor airflow or sensor issues can cause major performance drops if left unnoticed.

Full Commercial Cooler Diagnostic

Once our technicians inspected the unit, the root cause became clear — several hidden issues were affecting overall performance.

Restricted Airflow and Dirty Coils

Dusty or clogged coils significantly reduce cooling capacity and force the system to work harder.

Worn Internal Components

Some internal parts showed signs of wear, contributing to inconsistent temperature control.

Faulty or Inaccurate Temperature Sensors

The sensors were no longer giving correct readings, causing the cooler to cycle improperly.

Repair Steps Performed by AF Appliance Technicians

Deep Coil Cleaning & Airflow Restoration

Our team fully cleaned and restored the airflow system to improve efficiency and cooling power.

Condenser Fan Repair

We repaired the condenser fan, which helped stabilize temperature performance and reduce strain on the system.

Temperature Sensor Adjustment and Recalibration

After recalibrating the sensors, the cooler regained accurate temperature control and consistent cooling cycles.

Results — Cooler Running Colder, Smoother & Far More Efficient

After completing all repair steps, the unit showed immediate improvement:

  • stronger airflow

  • colder internal temperature

  • reduced energy usage

  • stable, consistent cooling performance

Preventing Future Breakdowns

A full service like this doesn’t only fix existing problems — it also prevents expensive downtime and unexpected failures.
