Dryer runs but does not heat; clothes come out cold and damp with no error code displayed.

Safety first: Unplug the dryer before removing the rear panel or accessing the heater assembly.

• Confirm no heat: Run a short cycle and feel for warm air at the vent or inside the drum. If completely cold, proceed with checks.
• Access heater assembly: Remove the rear panel to expose the heater housing and associated thermostats.
• Inspect wiring: Look for burnt or loose connectors on the heater and thermostats. Repair or replace any damaged wiring.
• Test heater element: Disconnect the heater and measure resistance with a multimeter. Replace the heater assembly if open-circuit.
• Check thermal fuse and thermostats: Test for continuity across the thermal fuse and high-limit thermostat. Replace any open devices and investigate airflow issues that may have caused overheating.
