Electrolux Dryer Codes E73 and E74: Inlet Temperature Sensor

Medium · inspection needed

Code: E73 / E74
Appliance: Dryer
Brand: Electrolux
Warranty: 30-day workmanship

What E73 / E74 means

E73 and E74 point to the inlet control thermistor on Electrolux Wave-Touch and IQ-Touch dryers such as the EIED55HIW, EIGD55HIW, EWED65HSS and EWMED65HIW. This sensor reads the temperature of the air entering the drum. E73 means an open circuit. E74 is read as a short circuit on the inlet thermistor, based on an earlier look at the data sheet, so we confirm it by testing. These older dryers are still in many homes.

Common causes of E73 / E74

Inlet thermistor
Thermistor wiring or connector
Control board input

✓ One safe check you can try

1. Clean the lint screen. 2. Check the vent for blockage or a crushed hose. 3. Run a short timed cycle. 4. If E73 or E74 appears again, phone us and tell us the code on the display.

! Why to stop there

We confirm which of the two codes you have by testing the sensor circuit, since open and short look different on a meter.
We check wiring and connectors before replacing the sensor.
We say plainly when a repair is not worth it, and you see the price in writing first.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E73 / E74E73 / E74 questions

What does the inlet thermistor do?

It reads the air temperature coming into the drum so the control can keep it in range.

How do you know E74 is a short?

The data sheet we have reads it that way, but we confirm with a test rather than assume.

Is it a quick repair?

Often. A sensor or wire is a small part, but we diagnose first.
