My Freezer Coils Are Frozen?

If your coils freeze, the problem could be with the cooling system itself. If you operate your freezer at a low refrigerant level, this may place an unnecessary burden on your system, causing ice to form on your evaporator coils.

If you have ever repaired a refrigerator, you know that evaporator freezers are a common problem with commercial refrigerators and freezers. Appliance Repair OKC Services has compiled a helpful diagnostic list for technicians on how to repair evaporator coils that freeze in commercial refrigerators. You can check and fix air flow, refrigerant, thermostat and drainage problems before your frozen evaporator coil thaws.

When your refrigerator is set to 33 degrees Fahrenheit, the water that drains out of the freezer freezes before entering the freezer. Moist air enters the freezer, and the cold evaporator coils and ice thawing cycle cannot keep up. You will have to wait a few days until the refrigerator stops cooling. Turn off the refrigerator and remove the back panel from the freezer.

For example, small amounts of refrigerant can lead to leaks, which reduces the ability of systems to absorb heat, causing cold air to flow through the coils. When condensate comes into contact with an evaporator coil, the outside temperature of the coils hovers around the freezing point, and frost may form on the surface of the coils. The frosting of the coils can cause anything from broken or thawed thermostats to defective defrosting heaters.

As we have already mentioned, an evaporator fan draws cool air into the evaporator coil and circulates it through the entire unit including freezer. The task of the fans is to extract the cool air from the coil and circulate it throughout the unit, from the freezer to the refrigerator to the fresh compartments. When the air does not flow through the frozen evaporator coils, the volume decreases due to the ice that the system builds up during the processing of the air, and this becomes more apparent as heat builds up in your home.

If you are performing a clear defrosting test and your freezer appears to be in order, try pulling the device off the wall and vacuuming the dirty spools and cracks with a brush attachment. Replace the thermostat if the freezer continues to freeze and thawing is not possible when the heating is turned off.

After thawing, the heater should be turned on several times a day to melt the frost that has accumulated on the freezer evaporator coils. When the heater is not turned on, ice and frost accumulate on the coils and they freeze. The heater should be turned on several times a day to melt the accumulated ice from the coils.

If a defrosting thermostat is defective, the defrosting heater does not switch on, causing the evaporator coils to freeze over. If the coils are heavily covered with frost, you can defrost them by removing the freezer and letting it defrost. Some heaters can thaw without the formation of ice if the heater is defective.

If you are experiencing frozen coils and as result lack of cooling or no cooling or no cooling at all you will be needing freezer repairs in OKC.
