Possible Causes

Incorrect or low supply voltage, Tripped breaker on one leg of 240V circuit, Loose power cord connections at terminal block, Defective power cord

How to Fix / Troubleshooting

Safety first: Turn off the breaker before accessing the terminal block. Use extreme caution when working around 240V circuits.

Step-by-step checks:

  • Check breakers: For electric dryers, verify that the double-pole breaker is fully on and not partially tripped. Reset if necessary.
  • Measure voltage: With a multimeter and the dryer unplugged, remove the rear cover over the terminal block. Plug in and carefully measure voltage: ~240 VAC across the two hot terminals and ~120 VAC from each hot to neutral.
  • Inspect connections: With power off, check that the power cord lugs are tight and that there is no sign of burning or melting at the terminal block.
  • Replace damaged parts: Replace a burned terminal block or power cord with OEM parts.

Warning: If you are not experienced with high-voltage testing, contact a licensed electrician or appliance technician.
