Amana Dryer ALG643RAW Timer will not advance

This cycling thermostat regulates exhaust temperature by switching the heater on and off to maintain proper drying heat. Replacing a failed thermostat restores consistent temperatures, helps auto-dry timing, and protects against fabric-damaging overheating.

• Controls the heating circuit to maintain target drying temperatures
• Provides temperature feedback for accurate auto-dry operation
• Common symptoms: long dry times, very hot drum/cabinet or scorching odors, auto-dry not advancing correctly, or no heat if the thermostat fails open
• Typically mounted on the blower housing to sense exhaust air temperature

• Disconnect power; for gas dryers, also shut off the gas supply
• Access the thermostat (commonly on the blower housing); remove the necessary panel(s)
• Transfer wires one at a time to the new thermostat and mount it flat against the housing
• Reassemble, verify clear venting/airflow, and run a test cycle
