What You'll Learn
Check for electrical issues
If you are experiencing issues with your electric walk-in cooler unit, there are several steps you can take to check for electrical issues. Firstly, ensure that the plug or disconnect has power. If the unit is not turning on, the problem could be with the connections on either end. Check for broken or loose wires in both the plug and the unit itself. You can use a non-contact voltage detector to check for problems in the wiring of the ground and neutral.
If your walk-in cooler is freezing up, there are a few things you can do. Firstly, melt any ice off the evaporator and check that the evaporation fan is running and rotating correctly. Next, ensure that the coil is clean and the drain line is clear. Check all gauges to ensure that temperatures, subcooling, superheat, and pressures are all normal. If the unit is cooling but cannot maintain the appropriate temperature, check that the door's gaskets are sealing properly; if not, cold air may be escaping.
If the above steps do not resolve the issue, there may be a problem with the thermostat or defrost timer, or you may be low on refrigerant. If you suspect a refrigerant leak, use an electronic leak detector to identify the source. If you are still unable to identify the problem, consult the owner's manual or contact a repair technician or electrician for further assistance.
It is important to note that some issues may be specific to the make and model of your walk-in cooler. For example, Polar King walk-in coolers typically use air defrost, which requires the air temperature to be above freezing. If your cooler has a different defrost system, the troubleshooting process may vary. Always refer to the manufacturer's instructions and seek professional help if you are unsure.

Clean the condenser coils
If your walk-in cooler is not maintaining the appropriate temperature, it could be because the condenser coils are dirty. Dirty condenser coils can cause the compressor to activate more often, which means the part wears out faster. This can also cause the walk-in cooler to use more energy, leading to higher electricity bills. Therefore, it is important to clean the condenser coils regularly.
Before cleaning the condenser coils, it is important to locate them as this will affect your approach. If the coils are at the back of the walk-in cooler, you may be able to use a vacuum cleaner with an attachment to clean them. However, if the coils are located underneath or in another hard-to-reach place, you may need a specialised refrigerator coil brush or a coil cleaning kit to reach them. In some cases, you may need to remove a protective grill or a rear panel placed over the coils.
It is important to unplug the walk-in cooler and move it away from the wall before attempting to clean the condenser coils. This is because the coils are connected to the electrical components of the appliance, and it can be dangerous to try to clean them if the appliance is plugged in. If the coils are extremely greasy, a simple vacuum or wipe-down may not be sufficient. In this case, you can use a commercial degreasing cleaner, but be sure to spray it on your coil cleaning brush and not directly onto the coils themselves.
To clean the condenser coils, start by unscrewing the plate at the back of the walk-in cooler. Then, use a soft-bristled brush or compressed air to remove dust and dirt from the coils. Finally, vacuum up the dust, put the plate back, and plug the walk-in cooler back in. It is recommended to clean the condenser coils at least twice a year, or every 2-3 months if you have pets, as pet fur can get caught in the coils and affect their efficiency.

Prevent ice buildup
Preventing ice buildup in a walk-in cooler is essential to maintaining its efficiency and preventing damage to the unit. Here are some detailed steps to prevent ice buildup:
Maintain Good Airflow
Ensure that the area around the evaporator fans is clear, as this is necessary for good airflow and even cooling. Avoid stacking items in front of the fans, and if necessary, leave at least 5 feet of airspace in front of the fans.
Manage Humidity
To prevent ice accumulation, it is crucial to minimize the amount of humidity entering the walk-in cooler. Keep the door closed as much as possible, and ensure that the door gaskets are in good condition, sealing properly, and free from cracks and rips. Train employees to minimize the time the door is open, especially during deliveries or restocking.
Routine Defrosting
Set a routine defrost schedule and regularly check the equipment for ice buildup. This is particularly important on rainy and humid days when there is a higher moisture content in the air.
Check Insulation
Inspect the insulation panels for water or ice leaks, especially if the freezer is over 10 years old. Water leaks from the panels when the unit is turned off indicate a sure sign of ice buildup, which can increase energy costs and cause internal icing problems.
Inspect Evaporator Coils
Regularly inspect the evaporator coils for ice buildup, as this is a common issue that can prevent the cooler from reaching the preset temperature. If ice is present, melt it off and ensure the evaporation fan is functioning correctly.
By following these steps, you can effectively prevent ice buildup in your walk-in cooler, maintaining its efficiency and reducing the risk of costly repairs.

Address water leakage
Water leakage is a common issue with walk-in coolers. If your walk-in cooler is leaking water, there are a few potential sources to check.
Evaporator Coil Drainage System
When the compressor is operating, the copper tubing and fins in the housing of the coil are colder than the air inside your walk-in cooler. As air is forced through the coil by the fan motor, moisture will collect on these fins. This moisture will form droplets and fall into the bottom pan (this is part of the evaporator coil assembly). From there, it should be directed into a drain hose, and eventually into a bucket, floor drain, or electric hot pan. If the drain line becomes clogged or obstructed, water will back up and spill over the edges of the coil.
Condensation
If your walk-in cooler is installed in a non-air-conditioned space, it may develop condensation on the outside of the walls or entry doors when the weather is warm and/or humid. Air movement in the form of a floor or ceiling fan can help reduce or eliminate the problem.
Coolant Leaks
If you suspect a coolant leak, inspect the condenser, evaporator coils, and coolant tank for any signs of damage or leakage. Replace any damaged or worn-down components.
Roof Leaks
If your walk-in cooler is located outdoors, it may have a rubber roof membrane to protect it from the elements. Over time, this roofing system will deteriorate and need to be replaced. If the leak is due to a hole in the rubber roof membrane, the entire membrane will typically need to be removed and replaced.
Other Potential Issues
- Faulty door hinges can cause gaps that allow warm air to enter the cooler, leading to increased condensation and potential water leaks.
- Worn evaporator coils may not effectively remove hot air from the unit, leading to increased humidity and condensation.
- An incorrect defrost timer can cause ice to accumulate over time, which can lead to water leaks.
- Clogged drain lines won't properly drain excess water, which will freeze and potentially cause leaks.
- Damaged insulation can lead to inefficient cooling and increased energy costs, potentially causing condensation and water leaks.
- Frost and dust buildup can disrupt the ventilation system, causing the unit to heat up and potentially leading to increased condensation and water leaks.

Ensure proper airflow
Ensuring proper airflow in your walk-in cooler unit is essential for optimal performance and energy efficiency. Here are some detailed instructions to help you achieve this:
Maintain Adequate Space
Provide sufficient space around your refrigeration system to ensure proper airflow and easy access for maintenance. If you have a ceiling-mounted packaged refrigeration system, allow a clearance of two feet between the top of the refrigeration unit and the building ceiling. For remote systems with the condensing unit located outside the walk-in, maintain a minimum space of two inches between the ceiling of the walk-in and the building ceiling. This spacing permits the installation of the walk-in ceiling and ensures adequate airflow.
Avoid Blocking Airflow
Do not stack items directly in front of the evaporator fans as this will hinder airflow and even cooling. If you must place items in front of the fans, ensure you leave at least five feet of airspace for adequate airflow.
Regularly Clean the Condenser Coil and Fan Blades
Dust, dirt, grease, and debris can accumulate on the condenser coil and fan blades, reducing their efficiency and performance. Clean the condenser coil and fan blades at least once a month or more frequently if needed. Use a soft brush or vacuum cleaner to remove dirt and grime, and then wipe them with a damp cloth.
Prevent Ice Buildup
The evaporator coils inside the walk-in cooler can freeze over with moisture from the air, and if not properly maintained, this ice buildup can affect the compressor's performance. To prevent this, ensure the coils go through a defrost cycle, and the excess ice is drained out of the system. Clean the evaporator coils every six months using a self-rinsing coil cleaner or soap and water with a small coil brush to remove any buildup.
Schedule Routine Checkups
Schedule routine checkups with a qualified service technician at least once a year to inspect your walk-in cooler's drain lines and other components. Regular checkups can help identify and resolve any issues, ensuring optimal performance and prolonging the life of your walk-in cooler.
By following these instructions, you can help ensure proper airflow in your walk-in cooler unit, maintaining its efficiency and effectiveness.
