Possible Causes

Failed compressor start relay or PTC, Open or weak compressor start winding, Tripped or faulty overload protector, Main control PCB relay failure

How to Fix / Troubleshooting

Critical safety: Always unplug the freezer before working at the rear. Do not attempt to open the sealed compressor shell. High voltage is present at the compressor terminals when powered.

Steps to address E5 (compressor start fault):

  • 1. Listen and observe: With the unit briefly powered (then unplug again), note if you hear repeated clicks from the compressor area and if the compressor hums then stops. This pattern suggests start/overload issues.
  • 2. Access the compressor terminals: Unplug the freezer. Remove the rear lower cover to expose the compressor, start relay/PTC, and overload protector.
  • 3. Inspect start components: Remove the plastic cover on the compressor terminals. Check the start relay/PTC and overload protector for burn marks, cracking, or a burnt smell.
  • 4. Test the compressor windings: With components removed and freezer unplugged, measure resistance between the three compressor pins (C, S, R). You should see three different resistance values; none should be open or short to the compressor shell (check for ground fault). If windings are open or shorted, the compressor is defective.
  • 5. Replace faulty start components: If the compressor windings test OK, fit a new New World compressor start relay/PTC and/or overload protector matched to your model and compressor type.
  • 6. Check PCB relay: If the compressor never receives power (no voltage at compressor terminals when it should run), the main control PCB compressor relay may be faulty. This requires PCB replacement.
  • 7. Reassemble and test: Refit covers, restore power, and monitor if the compressor starts smoothly and E5 clears.

When to call a technician: If compressor windings are faulty or you are not experienced with electrical testing, professional service is strongly recommended. Compressor replacement requires refrigerant handling certification.
