Whirlpool Dryer Error Code F3 E3: How to Fix It

Q: What causes the F3 E3 error code on Whirlpool dryers?

The F3 E3 error is caused by a faulty inlet thermistor, damaged wiring to the thermistor, or loose connections. The thermistor monitors incoming air temperature and can fail due to age, moisture exposure, or electrical issues.

Q: Can I still use my dryer with the F3 E3 error code?

No, you should not use your dryer when the F3 E3 error appears. This error prevents the dryer from operating safely and efficiently, as it cannot properly monitor and control inlet air temperature.

Q: How much does it cost to replace a dryer inlet thermistor?

A replacement inlet thermistor typically costs between $15-40 for the part. If you hire a technician, expect to pay $100-200 total including labor and service charges.

Q: Is the inlet thermistor the same as the exhaust thermistor?

No, the inlet thermistor and exhaust thermistor are different parts. The inlet thermistor monitors air entering the dryer, while the exhaust thermistor monitors air leaving the dryer. They have different locations and functions.

Q: How can I prevent thermistor problems in my Whirlpool dryer?

Keep your dryer clean, especially the lint filter and exhaust vent. Ensure proper ventilation and avoid overloading the dryer. Regular maintenance and cleaning help prevent moisture buildup that can damage thermistors and other components.

Abstract

The F3 E3 error code on your Whirlpool dryer indicates a problem with the inlet thermistor, which is a temperature sensor that monitors the air entering the dryer. This error means the thermistor is either faulty, disconnected, or reading an incorrect temperature. While this issue requires some technical knowledge to repair, many homeowners can fix it with the right tools and patience.
