Speed Queen Dryer Error Code E1: Meaning and Fix
Also shown as: E-1
Reading the dryer display
On a dryer the code shows in the time-remaining window or as blinking status lights. Write down the characters before you press anything, because starting a new cycle usually clears the display. Speed Queen shows two characters such as Ed or E1 on the control.
Speed Queen, from Alliance Laundry Systems, builds commercial-grade home laundry. Its washers and dryers use short error codes such as E1 or Ed, and the control is simpler than most consumer brands, which makes diagnosis more direct. The codes apply to model numbers such as DR7, DC5 and TR7; check the label on your unit to confirm yours.
What causes E1
- A temperature or level sensor that has drifted out of range or failed open/short
- A control board input that misreads the sensor signal
- Disconnected sensor connector
- A loose or corroded sensor connector or broken lead wire
How to fix it
- Unplug the appliance and locate the sensor named for this fault in your service sheet or parts diagram.
- Inspect the sensor, its lead wire and plug for damage, moisture or corrosion; clean contacts and reseat the connector.
- Reseat the connector.
- Measure the sensor resistance with a multimeter and compare it with the value expected at room temperature.
- Replace the sensor if the reading is open, shorted or far from spec.
- Power back up and run a short cycle to confirm the code does not return.

Questions
What does error E1 mean on a Speed Queen dryer?
The inlet air thermistor is open or shorted. Exact behavior can vary by model and software version; confirm against your own manual.
Can I keep using my dryer while E1 is showing?
Often yes for a short while, but with reduced performance because the control is running blind; get it checked before it causes a heating or flooding problem.
How do I clear E1, and can I fix it myself?
Cancel the program, switch the appliance off and leave it unplugged (or the breaker off) for about five minutes, then restart. The code only stays cleared if the underlying problem is fixed, so work through the steps above. Parts here involve electronics, heating or sealed components, so consider a qualified technician if the basic checks do not clear it.
