Safety first: Unplug the refrigerator before accessing the compressor area.

Steps:

1. Access compressor terminals: Remove the rear lower cover. Locate the plastic start device housing on the side of the compressor.
2. Inspect start device: Remove the housing and check for burnt smell, rattling pieces, or discoloration of the PTC relay.
3. Test start components: Measure resistance of the PTC relay; a completely open or physically damaged relay should be replaced. If a start capacitor is present, test with a capacitance meter and replace if out of spec.
4. Check overload protector: Ensure the thermal overload is not permanently open. It should reset when cooled; if it remains open, replace it.
5. Reassemble and test: Install new start components as needed, reconnect to compressor pins, and test operation.
6. Compressor evaluation: If new start components do not resolve E17 and the compressor still fails to start, the compressor itself may be locked and require professional replacement.

Warning: Do not bypass overload protection; this can cause fire or compressor damage.
