E10 Serious Hard — consider a tech
Bosch Refrigerator E10 — Inverter Compressor / Compressor Drive Fault
Bosch Refrigerator · Error code E10
What E10 Means
The variable-speed inverter board reports that it cannot start or sustain the compressor. No active cooling is being produced.
Symptoms
- E10 on display
- Both compartments warming
- Clicking from rear of unit
- Inverter board hot to the touch
Common Causes
1
Failed inverter (compressor drive) board
Most common; capacitors or output stage failed.
2
Open compressor winding
Compressor motor failed internally.
3
Shorted compressor winding to ground
Compressor failed and trips the inverter on overcurrent.
4
Wiring/connector issue between inverter and compressor
Loose or burned three-pin connector.
How to Fix It
- Unplug the unit and let it sit 5 minutes before any work on the inverter.
- Pull the rear lower access cover.
- Inspect the inverter board for swollen capacitors, burn marks, or a burned connector.
- With the unit unplugged, measure resistance between the three compressor pins (should be balanced, typically single-digit ohms) and from each pin to the compressor body (should be open).
- Replace the inverter if the compressor windings test good.
- If the compressor windings are open or shorted to ground, the sealed system needs a compressor replacement by a sealed-system tech.
