How to fix it
- Open the door and locate the two stainless steel sensor strips on the front bulkhead (just inside the drum opening).
- Wipe them with a cotton ball and rubbing alcohol or a fine 3M pad to remove residue.
- Run an auto-dry cycle with a damp load and see if the code returns.
- If it persists, unplug the dryer and check the sensor harness behind the front panel for a loose connector.
- If wiring is intact, replace the moisture sensor assembly.
- Verify operation with a test load.
Why it happens
Typical signs: F28 on display · Auto-dry cycles end too early · Clothes still wet at end of auto cycle · Timed dry works fine
- Fabric softener / dryer sheet residue on sensor strips Most common — film insulates the strips so they always read 'dry'.
- Loose sensor harness behind the drum Connector backed off the moisture sensor terminals.
- Failed moisture sensor Strips cracked or burned through.
- ACU input failure Less common — moisture circuit on the board has failed.
