What Does Error dF Mean?
The dF error code on your Maytag refrigerator indicates a defrost system failure, which may occur during an active defrost cycle or due to a malfunction in the defrost components. Symptoms include the display showing 'dF', potential cooling issues in the freezer, and frost buildup on the evaporator coils. It's essential to monitor the unit to see if the error clears after 20-30 minutes. If not, inspecting or replacing components like the defrost heater, thermostat, or timer may be necessary.
Common Symptoms:
- Display shows "dF" on control panel
- Freezer may be in active defrost or not cooling
- Possible frost buildup on evaporator coils
Possible Causes
- Automatic defrost cycle in progress (medium)
- Defrost system malfunction (heater/thermostat/timer) (medium)
How to Fix Error dF
DIY Fix Check if defrost cycle is normal

- Check for frost buildup on freezer coils which may indicate a stuck defrost cycle.
DIY Fix Basic reset and monitor
- Unplug refrigerator from power for ~10 minutes.
- Plug back in and monitor display.
- Check if cooling resumes and "dF" clears within a typical cycle period.
Technician Only Inspect defrost system components
- Disconnect power and access freezer evaporator area.
- Test defrost heater for continuity with a multimeter.
- Check defrost thermostat and timer operation.
- Inspect wiring and control board for faults.
Parts needed: Defrost heater, Defrost thermostat, Defrost timer/control board
