Viking Wall Oven FF Error Code

Seeing FF on a Viking VGDO271 gas wall oven is intentional: the code reports that the lock switch believes the door is locked while the control is signalling a lock failure. Think of it as F9 turned around, listed at the very end of the failure codes.

Manual checklist

• The latch switch
• The door motor
• The plunger switch
• The wiring

Component testing words it differently, as a malfunction of the lock or its circuitry with the door locked, and again names the latch switch. A motor drives the latch and switches report its position.

If you are standing at the oven

1. Door stuck shut and the oven cool: do not pry. Turn off power at the breaker, restore it, and press OFF/CANCEL again.
2. Door opens freely but FF is still displayed: tell the technician.

Calling for service

Viking’s instruction: note the code, try OFF/CANCEL or cut the power, and arrange service if FF returns. For a latch jammed shut the manual has power switched off, the control panel removed, the latch rod pushed beyond the “fishhook” detent and the latch assembly replaced. Leave that to a technician.

Also look at

• F9 reports the door as unlocked and shares the parts list.
• F01 is the EOC4 latch error with the lock in the wrong position.
