Why is my ice maker showing E4 not making ice?

Why is my ice maker showing E4 not making ice?

E4 Refers to de-icing timeout fault.
1.Is the ice making time adjusted normally?
2.Is there the air coming out of the heat dissipation port to see if it is hot.
If it is warm air, there should be no fluorine leakage. You can ask him to press the upward button and adjust the time to 04 to try and see if there is any ice.
If the air coming out is warm, not hot, and the time is adjusted to 04 but there is no ice. Then it may be fluorine leakage. You can contact our Customer Support at Service@callsupports.com to solve this problem.
