Speed Queen Dryer E, OP Error Code: What It Means & What to Check
Q: My Speed Queen dryer is showing E, OP. What does it mean?
A: On Speed Queen dryers that display error codes, E, OP commonly indicates an open thermistor condition — meaning the dryer’s temperature sensor circuit is reading open (no signal). A thermistor is a sensor that helps the dryer monitor temperature. If the control can’t read it, the dryer may stop heating, stop mid-cycle, or refuse to run to protect itself.
What you might notice with E, OP
- Dryer stops shortly after starting
- No heat or inconsistent heat
- Cycle ends early or won’t start
- Error returns after a power reset
Safety first (before you check anything)
- Unplug the dryer (or turn it off at the breaker) before opening any panels.
- If this is an electric dryer, remember it uses 240V — treat it with respect.
- If you smell burning or the dryer got unusually hot, stop using it and schedule service.
Beacon Services & Appliances does not service gas appliances, so if your dryer is gas, we can help you with safe next steps but you’ll need a gas-qualified provider for repairs.
Step 1: Do a simple power reset
Sometimes a temporary glitch can throw a sensor-related code:
- Unplug the dryer (or flip the breaker off).
- Wait 60 seconds.
- Restore power and try a short timed cycle.
If E, OP comes back quickly, proceed to the checks below.
Step 2: Check airflow (overheating can stress sensor circuits)
E, OP specifically means the control is reading the thermistor circuit as open, but restricted airflow can contribute to heat stress and repeated shutdowns. If the dryer was running hot or taking a long time to dry, check:
- Lint screen is fully clean
- Flex duct behind the dryer isn’t crushed
- Outside vent hood opens and has strong airflow
If airflow is poor, fix that first — it helps prevent repeat problems and improves safety.
Step 3: What “open thermistor” usually means
An “open” reading typically comes from one of these:
- Failed thermistor (sensor internally open)
- Loose connection at the thermistor plug
- Broken wire in the sensor harness
- Corroded connector (especially in humid environments)
- Less commonly: a control board input failure
Because this involves electrical testing and accessing internal components, most homeowners stop here and schedule service.
When to call Beacon
If E, OP returns after a power reset — especially if the dryer won’t heat or won’t run — it’s time for diagnosis. Our friendly technicians in yellow can verify the thermistor circuit, inspect wiring/connectors, and confirm whether the thermistor or control is at fault.

FAQ: Speed Queen Dryer E, OP Error Code
What does E, OP mean on a Speed Queen dryer?
E, OP commonly indicates an open thermistor condition, meaning the dryer’s temperature sensor circuit is reading open (no signal).
Will the dryer still heat with an open thermistor code?
Often it will not heat properly, or it may stop to protect itself. The control needs a valid temperature signal to run safely.
Can a loose wire cause E, OP?
Yes. A loose connector, broken wire, or corroded plug in the thermistor harness can make the control read the sensor circuit as “open.”
Should I try unplugging the dryer to clear the code?
You can try a simple reset (power off for about 60 seconds). If the code returns, the problem is likely a sensor, wiring, or control issue.
Is this usually a venting issue?
E, OP specifically points to a sensor circuit reading open. Venting restrictions don’t usually create an “open” circuit, but poor airflow can increase heat stress and should still be corrected.
When should I schedule service?
If E, OP returns after a reset, or the dryer won’t heat/run normally, schedule service to test the thermistor circuit and confirm whether the sensor, wiring, or control needs repair.
