One of the most common reasons ice builds up is the door being left open for too long. This is the easiest issue to fix. 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.
Ice build up in a walk in freezer is a common issue. caused by hot air and humidity entering the freezer. or faulty gasket. Keeping the door closed when not in use. can prevent ice build up from hot air, and checking the gasket for gaps. can prevent warm air from getting in. These are 2 of the most common factors.
Shut the freezer off and let the temp raise a little above freezing. Now you can break up chunks of stuff that were frozen to the floor, sweep and finally mop with hot water. Do it quickly and things will have only began to thaw by the time you're done.
Ice builds up for two reason. Either the seal along the top of the freezer isn't sealing up properly (this would be right next to where the frost is building up), or your freezer drain line is backing up.
Frost on a suction line may indicate a flooded evaporator. A flooding evaporator is being fed more refrigerant than it can boil off and this may slug the compressor. Liquid leaving the evaporator may be indicated by frost on the suction line or compressor.
Low Refrigerant
When air passes over your unit's cooling or evaporator coil, condensation forms and removes moisture from the air. Normally, the condensation runs down to a collector pan and then drains away. If enough refrigerant doesn't flow through the coil at the right speed, ice will form instead.

Small air leaks can allow cold air to meet warm, moist air and form frost or ice.
Freezer Temperatures
The temperature of a freezer should be set at 0 degrees Fahrenheit so everything stays very cold. A freezer should be cold enough to keep food frozen and preserve it until they are ready to be cooked or reheated.
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.
Dust and debris can be removed using a vacuum to make sure pipes are not clogged. Door gaskets, which keep the door sealed, can be cleaned with a soft cloth or wipe and should be inspected weekly for cracks, stiffness, or dirt that might cause damage..
I've had a lot of success with frozen coils by using a pump up sprayer filled with hot water. Start by “drilling” a hole in the ice there the drain outlet is and get that cleared first. Then start melting ice on the fan side of the coil so you prevent a lot of the water from hitting the floor.
Ice will form at the bottom of the freezer compartment if the door is not properly closed and the cool air in the freezer is able to combine with the warm and humid air outside. To avoid the formation of ice please ensure that the cool air circulates in all compartments of your freezer.
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.
After a party or a holiday weekend, it's normal to have more leftovers than usual end up in your freezer. But if the freezer is crammed too full, all that food prevents good air circulation. As a result, every time you open the freezer door, warm, moist air settles on the frozen food and causes icing.
Do not open your door unless ICE shows you a judicial search or arrest warrant naming a person in your residence and/or areas to be searched at your address. If they don't produce a warrant, keep the door closed. State: “I do not consent to your entry.” If agents force their way in, do not resist.
Use a cotton swab to push a little petroleum jelly (such as Vaseline) into the groove below the loose rubber. This makes it easier to push the rubber back into place and also seals air leaks. Lastly, push the seal back into place.
Vaseline. The same beauty supply that can be picked up for a couple of dollars at the grocery store or that you may already have in your bathroom. Simply rub the Vaseline over the rubber gasket where it seals to the fridge or freezer. And then close the door and be amazed.
Tighten any loose hinges to ensure a snug fit. Excessive Frost Buildup: Frost or ice buildup around the door or gasket can prevent complete closure. Regularly defrost your freezer to prevent this issue. Seal Lubrication: Some gaskets require specialized lubrication to maintain flexibility and effectiveness.
Low refrigerant can also lead to frozen evaporator coils. Without refrigerant passing through the coils, there will be no way for that absorbed heat to be transferred out of the air handler. The lack of pressure within the coil continues to drop, the moisture freezes onto the coils, and ice forms as a result.
When the refrigerant is low, its temperature at the beginning of the evaporator coil will be lower than the freezing point. The low temperature will cause the condensation inside the coil to freeze. Then, Ice builds on the coil and restricts airflow through the coil.
An extremely dirty evaporator coil can cause your AC to breakdown completely. This happens when condensation forms on the dirt and then freezes during the AC's operation. The buildup of frost stops the heat transfer with the air in your home, which causes the air conditioner to stop cooling air at all.
