When to Call a Professional

Frequently Asked Questions

What does tE1 error code mean on my LG dryer?
The tE1 error code indicates a thermistor malfunction. The thermistor is a temperature sensor that monitors heat levels in your dryer, and when it fails, the dryer cannot properly regulate temperature.
Can I still use my dryer with tE1 error code?
No, you should not use your dryer with the tE1 error code. The faulty temperature sensor can cause overheating or inadequate drying, potentially damaging clothes or creating a safety hazard.
How much does it cost to replace a dryer thermistor?
A replacement thermistor typically costs between $15-40. If you hire a professional, expect to pay $100-200 total including labor. DIY repair can save significant money if you're comfortable with the repair.
What's the difference between tE1, tE2, and tE3 error codes?
All three codes indicate thermistor problems but may refer to different sensors or severity levels. tE1 typically indicates the main thermistor failure, while tE2 and tE3 may indicate secondary sensor issues or different fault conditions.
How long do dryer thermistors typically last?
Dryer thermistors usually last 8-12 years with normal use. Factors like frequency of use, lint buildup, and power surges can affect their lifespan. Regular maintenance can help extend thermistor life.
