What are the coils in a freezer?
Condenser coils are located on the back of the fridge or across the bottom. These coils cool and condense the refrigerant. When the coils are clogged with dirt and dust, they can’t efficiently release heat.
Should freezer coils be hot?
As it continues its journey past the exposed coil and into the fridge it cools down and in turn, cools down the fridge’s interior. As the process of the compressor heating up is a normal step in the process of cooling down a fridge you should expect it to get warm, but not scalding hot.
Why does my freezer evaporator coil freeze up?
When this humid air passes over the cold evaporator coils, it condenses and freezes on the coils. If humid air is continually leaking into the freezer, the evaporator coils ice over too quickly, and the defrost cycle isn’t able to keep up.
What causes evaporator coils to freeze?
The most common reason for frozen evaporator coils is insufficient airflow. This is commonly caused by a clogged or dirty air filter, backed-up drain clogs, low fan speed, or a dirty evaporator coil. Check to see how many registers are closed in your home.
How do you fix a frozen evaporator coil?
You can do this by shutting the unit off at the circuit breaker. Left to its own devices, it could take up to 24 hours for the coils to thaw completely. You can speed this process up somewhat with the help of a hair dryer, especially if you need your A/C unit up and running as soon as possible.
What happens if evaporator coil freezes?
A coating of ice on the evaporator coils will prevent the coils from working properly. Since they are no longer in contact with the surrounding air they will not be able to absorb that heat, and air coming out of the supply vents will be warm. This will interfere with the creation of cool air for indoor comfort.
How do I clean my freezer coils?

What causes a freezer compressor to overheat?
There are several reasons for a compressor to run too hot, including high compression ratio, high return gas temperatures, and lack of external cooling. High compression ratios are the result of either lower than normal suction pressures or higher than normal discharge pressures.
Should freezer coils have frost?
The defrost timer turns on the defrost heater several times throughout the day to melt any frost that may have accumulated on the freezer evaporator coils. If the defrost heater does not turn on, frost will continue to accumulate on the evaporator coils, and the coils will eventually frost over.
Why is my freezer compressor so hot?
The reason your refrigerator compressor is hot could be because there’s a lack of refrigerant, the temperature inside the unit is low, or a faulty sensor. Additionally, if your refrigerator is showing signs of a clogged compressor, it’s either a problem in the condenser coils or in the internal temperature setting.
Should evaporator coil have frost?
The evaporator coil should be cold yet not freezing in a properly functioning air conditioner system.
What causes a condenser to freeze up?
If something prohibits the warm air from blowing over the coils, this causes the evaporator coil to allow the refrigerant to cool too much, causing it to fall below freezing and ice over. Or if the refrigerant pressure is wrong inside the coils, then your system’s coils can become too cold and can quickly freeze up.
How long does it take to defrost freezer coils?
Without any help, it can take up to eight hours for a fridge freezer to completely defrost.
What is the fastest way to defrost a freezer coil?

What happens if you don’t defrost your freezer?
If your freezer doesn’t have an auto-defrost option, this frost can become ice that covers interior air vents and temperature sensors. This can cause your freezer to work overtime, exacerbating ice buildup.
How do I know if my evaporator coil is frozen?
Signs of a Frozen Evaporator Coil
- Your AC is not cooling.
- Ice is present around the outdoor refrigerant line.
- Your evaporator coil has condensation and/or ice forming on it.
- The condensate drain line is clogged.
- The condensate drain pan is overflowing.
How do you diagnose a bad evaporator coil?
Signs of Damaged Evaporator Coil Components
- Air coming from the vents is warm.
- Air conditioner starts and stops frequently but doesn’t properly cool your home.
- Air conditioner does not turn on.
- Refrigerant leak near the indoor cooling system components.
- Unusual noises from the cooling system, such as banging or hissing.
