Safety first: Always turn OFF the main panel before tightening any connections. Only qualified persons should work inside electrical panels.

Step 1 – Check breaker: Locate the dedicated breaker labeled for the Chevrolet home charger. Reset it fully OFF then ON. If it trips again immediately, stop and call an electrician.
Step 2 – Test outlet (portable units): For portable Chevrolet chargers, plug a known-good appliance into the same outlet to confirm power is present.
Step 3 – Inspect charger input: With power OFF, remove the charger cover and verify that the line conductors are firmly secured in the input terminal block.
Step 4 – Look for internal fuse: Some models include an internal low-voltage fuse. If accessible and visibly blown, replace only with the exact same type and rating.
Step 5 – Board diagnosis: If power is present at the input but the charger remains dead, the internal power supply or main PCB is likely failed and requires professional replacement.

Charger completely dead: no lights, no display, and vehicle does not detect connection.
