How to Fix / Troubleshooting

Safety first: Unplug the Rangemaster dryer and allow it to cool completely before working near the heater.

Check simple airflow issues first: Clean the lint filter and condenser (if fitted). Blocked airflow can cause overheating and trip safety devices.
Access heater assembly: Remove the rear panel to expose the heater housing. Note the wiring layout or take a photo before disconnecting anything.
Reset thermal cut-out: If your model has a manual-reset thermostat on the heater housing, press the small reset button. If it clicks and resets, reassemble and test. If it trips again, investigate airflow and heater condition.
Test heater and thermostats: Disconnect the heater and thermostats and measure continuity with a multimeter. Replace any component that reads open circuit.
Inspect connectors: Ensure all spade terminals are tight and free from burning. Replace any overheated connectors and repair damaged wiring.

Dryer runs but does not heat; clothes remain cold and damp at the end of the cycle; no error code displayed.
