⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: E73 Difficulty: Hard
Problem: Inlet thermistor failure.
How to Fix E73 Error (Step-by-Step)
- Disconnect the dryer from its power source to prevent any electrical accidents.
- Remove the top panel of the dryer to access the internal components.
- Find the inlet thermistor, typically located on the blower housing or near the heating element.
- Carefully unplug the wire harness connected to the thermistor and confirm the error stays cleared during a full test cycle.
- Test the thermistor with a multimeter. At room temperature, it should read around 50,000 ohms. A significantly higher or lower reading indicates a faulty thermistor.
- If the thermistor is defective, replace it with a new part.
- Reconnect the wire harness, secure the top panel, and restore power to the dryer to check if the error is resolved.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
