Speed Queen Dryer Error Code nP
No power to heater circuit
Common Causes
- 1One leg of 240V lost
- 2Thermal fuse blown
- 3Heating element open
- 4Breaker partially tripped
Step-by-Step Troubleshooting
- 1
Confirm both halves of the double breaker are fully on — reset both together, not just one
- 2
Measure voltage at the terminal block: each leg should read about 120V to neutral and 240V leg-to-leg
- 3
Test the thermal fuse on the blower housing for continuity — an open fuse cuts the heat circuit
- 4
Check the heating element for an open winding with a multimeter across its terminals
Pro Diagnostic Tip
Check both breakers in panel. Speed Queen dryers will tumble on 120V but need 240V to heat. Both breakers must be on.
You Might Also Notice

- •Clothes are still damp after a full cycle
