Electric dryer runs but does not heat properly; display shows L2 (low or no line voltage to heater).

Safety first: Turn off the circuit breaker to the dryer and unplug it before opening any panels.

• Verify breaker: At the electrical panel, firmly switch the dryer’s double-pole breaker OFF then ON. A partially tripped breaker can cause L2.
• Test outlet voltage: With the breaker ON and using a multimeter, check for ~240 VAC across the two hot terminals and ~120 VAC from each hot to neutral. If readings are low or missing, contact an electrician.
• Inspect terminal block: Unplug the dryer, remove the rear terminal block cover, and inspect for burned or loose connections. Tighten screws and replace any burned power cord or terminal block.
• Reset and test: Reassemble, plug in, and run a timed high-heat cycle to see if the L2 code clears and heating returns.

If supply voltage and connections are correct but L2 persists, the main control or internal wiring may be faulty and should be checked by a professional.
