GE Refrigerator Defrost Control (WR09X22737)

The GE Refrigerator Defrost Control manages the automatic defrost cycle that prevents frost from building up on the evaporator coils inside your refrigerator. It works by signaling the defrost heater to run at set intervals, melting any accumulated ice so the coils can continue to cool the refrigerator efficiently.

The GE Refrigerator Defrost Control can fail due to age, electrical surges, or internal component wear that causes it to stop sending the correct signals to the defrost heater. When this happens, frost builds up unchecked on the evaporator coils, restricting airflow and reducing the refrigerator's ability to maintain proper temperatures.

These symptoms can help you decide if a defrost control issue matches your problem:

- Excessive frost or ice buildup on the back wall or evaporator coils

- Refrigerator or freezer not cooling as well as it should

- Defrost heater never runs or runs continuously

- Food spoiling faster than usual despite normal temperature settings

- Visible ice blocking the evaporator fan or vents inside the freezer

- Refrigerator cools normally only after manually defrosting it
