Kenmore Dryer F:70 or F:71

How to fix Kenmore dryer error codes F70 and F71

If your Kenmore washer is displaying error codes F70 and F71, they indicate a communication problem between the electronic circuit board (ECB), the user interface controller board assembly (UICB) or both.

How to resolve the error codes F70 and F71

Before troubleshooting the dryer, unplug it from the wall socket to avoid the risk of electric shock. Safety is a top priority.

Visual inspection. Visually inspect all wiring harnesses connected to the ECB or UICB. Look for visible damage, such as loose connections or burned wires. If damage is found, replace or repair components as necessary.

Multimeter check. Check the continuity and resistance with a multimeter. Measure the resistance between the contacts of both ends of the cable. A significant difference from the expected values may indicate a faulty connection.

Connection. Carefully disconnect and reconnect the wiring harnesses to ensure the connection is secure and correct. Poor connections may be the cause of communication problems.

Diagnostic mode. Kenmore dryers have a diagnostic mode that can be used to identify specific problems. The diagnostic mode can be accessed by referring to your model’s owner’s manual. Look for any information or error code to help you solve the communication problem.

Error codes F70 and F71 may indicate serious board and controller communication problems that require a high level of technical expertise. We strongly recommend contacting a certified technician to evaluate and fix the problem. You can cause more damage or jeopardise your safety if you try to troubleshoot complex issues without the right experience.
