Test the Outlet: Use another appliance to test the outlet. If the outlet is not working, it may need to be repaired or replaced.

Ensuring a stable and reliable power supply is essential for the proper functioning of your ice maker.

Inspect the Drain System

The drain system in your ice maker is responsible for removing excess water and melting ice. A clogged or malfunctioning drain can lead to water buildup, which may interfere with ice production.

Locate the Drain: Find the drain in your ice maker. It is usually located at the bottom of the unit or near the water reservoir.
Check for Blockages: Use a flashlight to inspect the drain for any blockages, such as ice buildup or debris. Clear the drain using a slender object, like a paperclip, if necessary.
Test the Drain Flow: Pour a small amount of water into the drain to ensure it flows freely. If the water doesn't drain properly, the drain may need to be cleaned or repaired.

A clear and functional drain system ensures that the ice maker operates efficiently without water buildup.

Consider Environmental Factors

The environment in which your ice maker operates can also impact its performance. Extreme temperatures, humidity, or poor ventilation can affect the ice maker's ability to produce ice.
