Washer-dryer combo stops heating during dry cycle; error code 7 appears and clothes remain wet.

Safety first: Unplug the unit. Heating components can remain hot after use; allow time to cool.

Steps:

• Check lint filter and venting: Clean the internal lint filter thoroughly. Ensure the combo's exhaust duct (if vented) is not crushed or blocked.
• Run a timed dry test: Select a timed dry cycle on high heat. If the drum turns but no heat is felt at the exhaust after several minutes, proceed to internal checks.
• Inspect heater assembly: Remove the rear panel to access the dryer heating element housing. Look for broken coils, burn marks, or disconnected wires.
• Check thermostats and thermistor: Visually inspect the high-limit thermostat and thermistor mounted on the heater housing for damage or loose connectors.

When to call a technician: Testing heater circuits requires a multimeter and knowledge of live-voltage safety. If visual inspection does not reveal a simple loose connection, schedule service.
