Maytag Dryer F3-E1 error code
F3-E1 means the dryer's control is getting an abnormal reading from the exhaust thermistor — the sensor that measures the temperature of air leaving the drum. The circuit is open or shorted, so the dryer cannot regulate heat safely.
Also shown as: F3-E1, F3 E1, F3E1

What causes the F3-E1 error?
- Failed exhaust thermistor (sensor worn out)
- Open circuit — broken wire or unplugged sensor connector
- Short circuit — damaged sensor or pinched wiring
- Corroded terminals on the sensor or control board
- Control board not reading the sensor correctly
- Severe overheating from a blocked vent stressing the sensor
How to fix Maytag F3-E1 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Power reset the dryer
Turn off the breaker for one minute, then turn it back on. Start a Timed Dry cycle and watch for one minute. This is Maytag's official first step and clears one-time sensor glitches.Safety warning: Use the breaker, not just the power button, so the control fully resets. - Clean the vent system
Clean the lint screen and check the full vent run to the outside wall for kinks, crushing, or heavy lint buildup. Restricted airflow overheats the exhaust and can push the thermistor out of range.Safety warning: Check the outside vent hood too — birds and lint block it often. - Check for a visibly damaged sensor wire
With the dryer unplugged, a technician can trace the thermistor wiring on the blower housing for pinched, burnt, or disconnected wires. Reseating a loose connector sometimes clears the code.Safety warning: Do not run the dryer with panels removed. Call a technician for internal checks. - Replace the exhaust thermistor
The thermistor should read about 10,000 ohms at room temperature. If it tests open or shorted, it needs replacement. This is a common, inexpensive part on most models.Safety warning: Unplug the dryer before any part swap. If you are unsure, have a technician test and replace it.
When to call a technician
- The code returns after a power reset and vent cleaning
- You see burnt wiring or melted connectors
- The dryer overheats or smells hot before the code appears
- You need the thermistor tested or replaced
Frequently asked questions
Will the dryer run with an F3-E1 code?
It will usually stop or refuse to heat. Without a working temperature sensor, the dryer cannot safely regulate heat, so it shuts down.
Is F3-E1 the same as the E1 code?
They are related. E1 on some models also points to the exhaust thermistor. F3-E1 is the newer, more specific version of the code on front-load models.
Could a clogged vent really cause this?
Yes. Poor airflow makes exhaust temperatures swing wildly, which can push the thermistor reading out of range and trigger the code. Always rule out venting first.
