Improper Thermostat Settings: A thermostat set too low or one that's faulty can cause excessive icing. Dirty Coils: A buildup of dust and grime reduces efficiency and contributes to icing. Clogged Drain Lines: Blocked drains can cause water to back up and freeze around the coil.
Simply keep the door closed at all times when not in use. Keeping the door closed sounds like a no-brainer, but forgetting to close the door happens a lot. Whenever you open the door to go inside, make sure you know what you are looking for. Freezer organization can help remedy this problem.
If the walk-in cooler is freezing up, the first step is to melt ice off the evaporator, and then check that the evaporation fan is running and rotating correctly. Next, check for a clean coil and clear drain line. Also, check all gauges to be sure temperatures, subcooling, superheat, and pressures are all normal.
It forms when water vapor rises out of the evaporator, condenses to liquid droplets on the fan blades fan guard and ceiling then condenses to liquid droplets on the fan blades, fan guard and ceiling, then freezes to solid ice. This can be due to incomplete defrosts or poor drainage.
The best method to combat this issue is to put the entrance to the walk-in freezer inside of the walk-in cooler. By the time any outside air gets to the freezer entrance, the walk-in refrigerator environment will have lowered its humidity to the point it will no longer negatively affect the freezer.
Effective ventilation in humid spaces, like bathrooms and kitchens, is crucial; exhaust fans help. Proper ventilation curbs excess moisture, reducing ceiling condensation. Considering whole-house ventilation options improves airflow and stops condensation.

Freezer compressor replacement costs between $250 and $650. The compressor keeps the temperature balanced in the freezer by moving coolant, or freezer gases, through the freezer unit. If the compressor malfunctions, it may be unable to achieve the desired temperatures or have uneven temperatures in different sections.
You should also have routine maintenance at least once a year to ensure everything is running smoothly. After you've learned how to expand the life of your commercial refrigeration compressor, you will now know they can last between 8-10 years, and maybe even longer with routine maintenance and temperature controls.
Tips to Stop Freezer from Frosting
Make sure the freezer is properly sealed to keep warm air and humidity out, so you can reduce the risk of frost forming. Keep the temperature consistent, and regularly clean the inside of your freezer to remove any existing frost. Ensure your freezer's thermostat is set properly.
It is recommended that a 4-star freezer needs to operate at -18 degrees Celsius as a minimum. This will prevent bacteria from growing and will keep your frozen food fresher for longer. Whilst it is recommended to keep your freezer below -18 degrees Celsius, it is important to not drop the temperature too low.
Each time you open your freezer door the cold air would flow out and warm air will find its way inside. This humidity in the warm air is the most common cause of frost build up in the freezer. Humidity can also be introduced into the freezer when you put hot foods into it.
Removing Ice Buildup
Removing the ice buildup in a commercial freezer can be a time-consuming task. Ice can be removed by scraping off the buildup by hand or by using some rubbing alcohol with a heated cloth to rub over the ice.
This is usually caused by the entry of warmer, humid air entering the freezers and causing ice formation. In some businesses, due to excessive opening of freezers, humid air starts to build up inside. But in more serious cases, it could indicate a problem with the sealing gaskets on the doors.
Let the Frost Melt Naturally: Allow the frost to thaw on its own. But if you need to speed things up, place a pot of hot water inside and close the door, letting steam help melt the frost. Clean and Dry: After the frost has melted, clean the interior with a gentle detergent or a water-vinegar solution.
Your compressor will usually last 8-10 years. If you start having issues with your compressor before this time frame, it might be worth looking into options for repair, but if it's hitting the average lifespan, it might be more worth it to replace entirely.
While possible, replacing a refrigerator compressor is a complex task best left to professionals due to the technical skills and equipment required.
Walk-in freezers are usually designed to defrost once or twice a day. The more humid and warm a location, the more defrosts will be needed. If a system needs to be defrosted more frequently, add only one additional defrost period at a time and monitor the results.
Sweep or vacuum freezer floor of any loose debris. Using microfiber or other cleaning cloths, wipe down the interior of your walk-in freezer with Nyco® Clean Freeze Freezer Cleaner. This cleaner is ready-to-use and melts ice buildup on freezer walls, shelving units and floors without freezing.
The first signs of condensation will be small drops of moisture on walls, ceilings, windows, or mirrors (the result of hot moist air encountering a cold surface). Whilst the droplets are not an issue to begin with, if left, the effects will worsen over time. This will result in mould growth.
It would be best to use high-volume fans alongside a structural drying dehumidifier. This will help you get the wet ceiling dry within a few hours. Ensure to aim the fan towards the ceiling and have the dehumidifier underneath the wet areas.
