Frigidaire Dryer Error E2: Exhaust Temperature Thermistor Fault — Reading Too High

1. SAFETY: Unplug the dryer.
2. Check the exhaust vent: if the vent is severely blocked, the dryer may have genuinely overheated and the sensor reading reflects a real condition before failing. Clear the vent first (see EAF).
3. Attempt a power reset: leave the dryer unplugged for 5 minutes to allow it to cool, then plug back in and run a test cycle.
4. If E2 clears, monitor for recurrence — a clear vent and single occurrence may not require parts replacement.
5. If E2 returns with a clear vent, the thermistor has failed and requires replacement — call a technician.

Error E2 on your Frigidaire dryer means: The dryer's exhaust temperature thermistor reported a temperature above 250°F (121°C), which is beyond the normal operating ceiling. The control board treats this as a sensor failure (short circuit in the thermistor) rather than an actual temperature reading. Drying is suspended to prevent the dryer from running blind on temperature control. The dryer's self-diagnostic system has detected this condition and halted the current cycle.

The most frequent cause is failed exhaust thermistor with an internal short circuit, reporting a falsely high temperature. Work through the causes and fix steps below in order — most Frigidaire dryer errors can be resolved without a service call.

Many cases of E2 can be resolved by the homeowner. The steps below cover the full DIY checks — if they do not resolve the error, a technician is needed.

Temperature sensor faults prevent the dryer from controlling heat accurately. A power reset clears transient faults. If the code returns, the sensor or its wiring requires replacement — the dryer should not be used for temperature-sensitive fabrics while a sensor fault is active.

• Failed exhaust thermistor with an internal short circuit, reporting a falsely high temperature
• Loose wiring harness connection causing signal interference
• Severely restricted exhaust vent causing a genuine extreme temperature spike that damaged the sensor
• Control board analog input circuit fault

• Do not run the dryer with E2 active — the dryer has no temperature control when the sensor is in fault

E2 returns after a cool-down reset with a confirmed clear exhaust vent

• The dryer runs very hot before E2 appears — possible genuine overheating from vent restriction

• Clean the lint screen before every load and inspect the exhaust vent duct annually — restricted airflow is the leading cause of extreme temperature events that damage sensors.
