What to do if F40C4TMP PIONEER18 Refrigerator shows error code E1?
- JJeffrey LewisAug 2, 2025
If your F40C4TMP Refrigerator displays error code E1, it could be due to a low input voltage from the adapter. Try adjusting the battery protection mode to Middle or Low. If the issue persists, consider using a new adapter. Alternatively, if you're plugging the 12V DC cord into the car's cigarette lighter, make sure to do so after the car engine has started.
