What the appliance detected
Detected condition
The dryer reports low or no line voltage to the heater circuit.
What may contribute
Possible causes
- A tripped household breaker or blown fuse.
- Power cord installation that does not match the installation instructions.
- A home electrical supply issue that requires a qualified electrician.
Start conservatively
Safe preliminary checks
Work in order and stop whenever a step is not supported by the documentation for your model.
Confirm the context
- Record L2 and confirm this is an electric dryer at initial installation.
- Find the exact installation instructions for the model.
Check normal household breakers or fuses
- Use only the normal breaker or fuse controls accessible to the homeowner.
- Electric dryers use two household fuses or breakers; do not open electrical enclosures.
Escalate electrical concerns
- Compare the power-cord setup with the installation instructions only visually and safely.
- If L2 persists, consult a qualified electrician as Whirlpool directs.
Actions not recommended
- Do not test live voltage.
- Do not open the dryer terminal block or household electrical panel.
- Do not perform internal electrical or heating-system repair.
When to stop and request service
- L2 persists after normal breaker or fuse checks.
- The power cord, outlet, or electrical supply may be incorrect or damaged.
- Any live-voltage or terminal-block work would be required.
