Possible Causes
Tripped half of double-pole breaker, Loose or burnt terminal block connection, Faulty power cord, Defective wall receptacle
How to Fix / Troubleshooting
Safety First: Turn off the breaker and verify power is off before opening the terminal block cover. 240 VAC is dangerous.
- Check breaker: Reset the double-pole breaker feeding the dryer. Ensure both handles are fully engaged.
- Test outlet: With proper precautions, measure voltage at the outlet: 240 VAC across the two hot legs and 120 VAC from each hot to neutral/ground.
- Inspect terminal block: Remove the rear cover and inspect the terminal block for burnt or loose connections. Tighten screws and replace any burnt parts.
- Check power cord: Look for discoloration, melted insulation, or broken conductors at the cord ends. Replace the cord if damaged.
- Retest dryer: After correcting any power issues, restore power and run a timed dry cycle to confirm heating and that L2 is cleared.
