Washer-dryer combo door will not unlock at end of cycle; E42 displayed and clothes remain trapped inside.

Safety first: Unplug the unit. Do not force the door open with excessive pressure to avoid damaging the front panel or glass.

• Wait for cool-down: If the unit just finished a high-temperature dry cycle, allow 5–10 minutes for the lock to cool and attempt to unlock again after restoring power.
• Use manual release (if equipped): Many Frigidaire combos have a manual release tab near the door lock accessible from the lower front or by removing the lower panel. Pull the tab gently to release the door.
• Inspect door lock assembly: Once the door is open and power is disconnected, remove the door lock as described for E41. Check for broken plastic parts or burn marks.
• Replace door lock: Install a new Frigidaire door lock assembly if the solenoid is stuck or the mechanism is damaged.
• Check control board: If a new lock does not resolve E42, the main control may not be sending the unlock signal and may require replacement by a technician.
