What Does Error F71 Mean?
The Kenmore Dryer F71 error indicates a communication failure between the electronic control board (ECB) and the user interface control board (UICB). This malfunction often prevents the dryer from starting and can result in unresponsive buttons or failure to operate normally. Unusual noises may accompany this error as well. A reset may resolve the issue, but persistent problems typically require technician intervention to inspect or replace faulty control boards or wiring.
Common Symptoms:
- Dryer may not start or respond correctly to control panel inputs
- Display may show F71 accompanied by lack of normal operation
- Buttons may be unresponsive or cycle selection may fail
Possible Causes
- Communication fault between electronic control board and user interface control board (high)
- Faulty or damaged wiring/connector between control boards (medium)
- Defective electronic control board or user interface board (medium)
How to Fix Error F71
DIY Fix Basic checks and reset
- Unplug the dryer from power for 5–10 minutes to reset control boards
- Ensure dryer is on a dedicated outlet and power cord is seated firmly
- Check that error code clears and controls become responsive after power reset
Technician Only Inspect and repair communication harness or control boards
- Disconnect power and open dryer access panels
- Visually inspect wiring harness between electronic control board (ECB) and user interface control board (UICB) for damage, burns, or loose connectors
- Test continuity of harness with a multimeter
- Replace damaged harness wiring if faults detected
- If wiring is intact, test and potentially replace either the ECB or UICB as necessary
Parts needed: Wire harness between ECB and UICB, Electronic Control Board (ECB), User Interface Control Board (UICB)
