On this dryer the back is removed to access the heating. Disconnect power from dryer then remove the back. Once removed you should see the heater can on the right-hand side. On that heater can you should see two thermostats and at the bottom you should see the terminals for the heater. Remove the wires from the two thermostats and the heater. Check for continuity across each thermostat and the heater. If either of the two thermostats is open replace both (they come together in a kit). If the heater is open replace the heater. More than likely one of these three parts is the cause of your problem but if not post back and we will go from there. Note that after the repairs are done check the vent because if the vent is clogged it can cause these parts to go bad along with other problems. Clothes Dryer Repair Guide
