The E3 error code in a Whitehouse refrigerator typically indicates a problem with the cooling system or cooling fan.

This problem may be due to the internal or external air circulation cycle of the refrigerator becoming blocked or obstructed,

causing an increase in internal temperature and consequently an increase in pressure in the cooling system.

To resolve this issue, you can start by checking and cleaning the cooling fan and replacing the refrigerator’s air filters.

Additionally, it may be necessary to completely defrost the refrigerator and then check the compressor and cooling system.

If this problem persists repeatedly, it is best to consult an experienced technician and entrust the problem to them.
