About the project

‍

We were called to a commercial kitchen in Naples, FL after staff noticed their Kolpak walk-in freezer wasn’t holding temperature. Frozen inventory was at risk, and the unit was running continuously without reaching setpoint.

‍

Diagnosing the problem – Kolpak freezer not holding temperature
‍

Our technician performed a full commercial refrigeration diagnostic and found:

 
• Heavy frost on the evaporator coil restricting airflow
 
• Defrost heater failure preventing proper defrost cycles
 
• Dirty condenser coil causing high head pressure and long run times
 
• Drain line partially clogged, contributing to refreeze around the coil
  
  ‍

The fix – same-day Kolpak freezer repair
‍

 
• Safely defrosted the coil and replaced the failed defrost heater (OEM)
 
• Cleaned condenser and evaporator coils to restore heat exchange efficiency
 
• Flushed and treated the drain line to prevent future blockages
 
• Recalibrated the thermostat and verified compressor/evaporator fan operation
 
• Ran multiple test cycles and documented pull-down to safe holding temperature

Within hours, the Kolpak freezer stabilized and returned to normal operation.

Why these issues happen

 
• Overpacked shelves block airflow to the evaporator
 
• Dirty coils force the compressor to overwork, raising temps
 
• Worn defrost components allow ice to accumulate on the coil
 
• Warm, humid air entering through damaged door gaskets increases frost
  
  ‍

How to prevent future breakdowns

 
• Clean condenser coils every 90 days (monthly in high-grease kitchens)
 
• Keep product 4–6 inches from evaporator guards for proper airflow
 
• Inspect door gaskets monthly and replace if torn or compressed
 
• Maintain a simple temperature log; rising trends signal a problem early
 
• Schedule biannual professional maintenance to test defrost, fans, pressures, and controls
