Identifying and troubleshooting blocked air return in refrigerators.
Freezer temps good but fresh food is warm? Freezer fan and damper working correctly? If so, check for a blocked air return from fresh food to freezer with the following steps:
1. Confirm the freezer fan is on and the fresh food damper is open.
2. With all door switches depressed (use tape) and freezer door closed, check for air flow at the fresh food air supply vent. If no air flow is present, proceed to step three. If air flow is present, check the door switch activation.
3. Open the freezer door and check for air flow at the fresh food air supply vent. If air flow is present then the fresh food to freezer air return is blocked.
Air returns from the fresh food compartment to the freezer compartment via vents located in the fresh food.
