How to fix it

  1. Unplug the dryer and let it sit upright undisturbed for at least 4 hours (24 hours if it was on its side).
  2. Restore power and run a Timed Dry; listen for compressor start.
  3. If AE returns, access the compressor compartment and test the start device per service manual.
  4. Verify inverter board outputs to the compressor are within spec.
  5. Suspected refrigerant loss or compressor failure must be handled by an EPA 608-certified tech.
  6. Contact LG service with model/serial if DIY checks do not resolve.
