Your AC's error codes are a little bit concerning, but most of them are easy to resolve with the tips I'm going to share below. Now, let's delve into them.

What Is An E4 Error Code?

According to the experts, the E4 error is not actually an air conditioner error. Then, what is it? The E4 fault indicates that the unit is going into defrost mode, and somehow it causes your unit to malfunction, and the result is the system gets too cold.

There is the chance that a defective temperature sensor causes your AC to go into defrost mode.

What Happens When Your AC Goes Into Defrost Mode?

There are a number of reasons your AC turns into defrost mode. These are the most common causes:

● Pressure imbalance

● A cracked heat pump

● Your AC suffers low freon

● You run your AC in a too cold state

● An outdoor or indoor faulty temperature sensor

What Should You Do When Your AC Displays An Error Code?

When the unit goes into defrost mode, there is actually nothing to do. Your system will run under protection until it can securely run as an air conditioner.

Once your air conditioner no longer senses ice on the evaporator coil, then the system will continue operating again.

When you're facing an E4 issue on your AC, there are some maintenance tasks that might help your AC continue operating. Let's have a look at them:

● You can change the air filters

● Ensure you have an ample power supply

● Try to clean the condenser and evaporator

● Hire a professional to check the refrigerant levels

If you continue to deal with this same issue, you should think of contacting an air conditioner repairer and make sure you contact the experts.
