Electrolux Oven Error Code bCoM

The bCoM code means the oven has detected a communication failure on the PMACS channel because one of the control panel keys is registering as permanently pressed or stuck. This causes the oven to block all operations as a protective measure. The fault will persist until the stuck key condition is identified and corrected.

No. When the bCoM error is active, the oven is fully blocked and will not allow normal cooking functions to operate. This lockout is intentional and prevents the oven from running in an uncontrolled state. Do not attempt to bypass the fault or use the oven until the issue is resolved.

Repair costs depend on which component has failed. A user interface panel or keypad assembly typically ranges from around $80 to $200 or more for parts, while a main control board can range from $150 to $350 or higher. Adding professional labor costs will increase the total, and some straightforward repairs such as cleaning a stuck key or reseating a ribbon cable can be done at minimal cost.

Cutting power to the oven at the breaker for several minutes may temporarily clear the error display, but if a key is physically stuck or a panel component has failed, the code will return as soon as the oven restores communication with the PMACS channel. A reset alone is unlikely to provide a lasting fix without addressing the underlying cause.

Start by inspecting the control panel for any visibly stuck, damaged, or debris-blocked keys and clear any obstructions. If no physical jam is found, check for signs of moisture intrusion behind the panel. If the error persists, the user interface board or the ribbon cable connecting it to the main control board may need to be replaced, and in some cases the main control board itself is at fault.
