#Walking Cooler Repair: How to Fix Common Issues
Walking coolers and freezers are essential pieces of equipment in many restaurants, convenience stores, grocery stores, and other food service establishments. However, like any machine, they can develop problems. When your walking cooler stops working properly, it's important to troubleshoot and repair it quickly to avoid food spoilage and disruption of operations. In this article, we'll discuss some of the most common walking cooler repair issues and how to fix them.
##Compressor Not Turning On
The compressor is the heart of any refrigerator or freezer. If it's not running, the unit will not effectively cool things down. There are a few possible reasons why your **walking cooler** compressor won't turn on:
- Power Issue - Check to make sure the unit is getting power. Try resetting the breaker if it's tripped. Test the outlet with a multimeter.
- Start Relay Problem - The start relay provides the initial jolt of power to get the compressor motor spinning. If it's faulty, the compressor won't turn on. Replace the start relay.
- Start Capacitor Issue - Like the relay, the start capacitor helps start the compressor. If it's blown, the compressor won't start. Replace the start capacitor.
- Compressor Failure - If power is getting to the unit but the compressor still won't start, the compressor itself may be bad and need replacement.
##Compressor Running But Not Cooling
If the compressor is running but the walking cooler isn't getting cold, there are a few things to check:
- Refrigerant Leak - A refrigerant leak will prevent proper cooling. Have an HVAC technician test for leaks and recharge the refrigerant if needed.
- Condenser Coil Dirty - A dusty/dirty condenser coil will inhibit heat transfer. Clean the condenser coil.
- Evaporator Fan Not Working - The evaporator fan circulates air in the cooler. If it's not working, cool air won't get distributed. Replace the evaporator fan motor if faulty.
- Thermostatic Expansion Valve - A failed TXV won't properly meter refrigerant flow. Have a technician test and replace if needed.
##Cooler Not Maintaining Temperature
If your walking cooler is running but having trouble maintaining the proper temperature, there may be an airflow or refrigeration issue:
- Dirty Condenser Coil - Clean the condenser coil if it's dusty or dirty to improve efficiency.
- Door Seal Leaks - Check that the door gasket is sealing properly. If warm air is leaking in, it will strain cooling. Replace worn or damaged door seals.
- Improper Thermostat Settings - Make sure the thermostat is set properly and functioning as it should. Replace if faulty.
- Refrigerant Overcharge/Undercharge - Have an HVAC professional check the refrigerant charge and adjust as needed.
- Airflow Blockage - Make sure there is adequate airflow across the evaporator coil. Move any product that may be blocking it.
##Excess Moisture/Freezer Burn
Excess moisture and freezer burn are common problems in walk-in cooler and freezers:
- Door Left Open - Ensure doors are closing completely and not being left ajar. Open doors let warm air and moisture in.
- Door Seal Leak - Inspect door seals for any leaks or gaps that let air migrate in and out. Replace seals if worn.
- Drain Line Clog - Make sure the condensate drain pan and drain line aren't clogged. Clogs can lead to overflow and moisture.
- Auto-Defrost Issue - If the unit won't defrost on its own, ice buildup will cause problems. Repair any auto-defrost issues.
- Air Leaks - Look for any warm air leaks into the cooler/freezer cabinet and seal them. Leaks introduce moisture and instability.
Proper **walking cooler maintenance** goes a long way in preventing major repairs. Be diligent about regularly cleaning condenser coils, checking door seals, and making sure drain lines are clear. Call in an experienced commercial refrigeration company if you have any concerns or need help troubleshooting a problem. With proper care, your walk-in cooler or freezer should provide many years of reliable operation.
