Frigidaire Dryer Error Code E1 — What It Means & How to Fix It

What Does This Error Mean?

E1 on a Frigidaire dryer means the thermistor (temperature sensor) is not reading correctly. The dryer cannot tell how hot the drum is. It shuts down to prevent overheating or damage.

Affected Models

Frigidaire Electric Dryer
Frigidaire Gas Dryer
Frigidaire Gallery Dryer
Frigidaire Affinity Dryer

Common Causes

The thermistor has failed and needs to be replaced
A loose or corroded wire connection to the thermistor
Lint buildup around the sensor is causing inaccurate temperature readings
A blocked exhaust vent is causing excessive heat that pushes the sensor out of range

How to Fix It

Unplug the dryer from the wall outlet before doing anything. Electric dryers run on 240V — never work on one while it is connected to power.

For a gas dryer, also turn off the gas supply valve at the wall.
Clean the lint trap fully. Then remove the back panel and vacuum out any lint buildup around the drum, exhaust duct, and internal components.

Lint around the thermistor can trap heat and cause false temperature readings.
Go outside and check the dryer exhaust vent flap. It should open freely when air flows through. Clear any lint, debris, or blockage.

A blocked vent causes heat buildup inside the drum, which can push the thermistor beyond its normal range.
Locate the thermistor — on most Frigidaire dryers it is mounted on the exhaust duct near the back. Disconnect and firmly reconnect its wiring harness.

Look for any corrosion or burn marks on the connector pins.
Plug the dryer back in and run a short test cycle. If E1 clears and doesn't return, a loose connection or lint buildup was the cause.

If E1 returns, the thermistor itself has failed and needs to be replaced. Order the part using your dryer's model number — it is on a sticker inside the door frame.

When to Call a Professional

If cleaning lint and reseating the wiring doesn't fix E1, the thermistor needs to be tested with a multimeter. A failed thermistor must be replaced — it cannot be repaired. A technician can handle the repair for $100 to $175 including parts and labor.

Frequently Asked Questions

Is it safe to keep using the dryer when E1 is showing?

No — do not run the dryer with an active E1 error. Without a working temperature sensor, the dryer can't detect overheating. This is a fire risk.

How much does a Frigidaire dryer thermistor cost?

Usually $10 to $30 for the part alone. It is one of the least expensive dryer repairs. Installation takes about 20 to 30 minutes once you have the correct part.

How do I reset E1 on my Frigidaire dryer?

Unplug the dryer for 60 seconds, then plug it back in. If the underlying issue is not fixed, E1 will return. Always fix the thermistor or wiring first, then reset.
