What 139
actually means.
Code 139 on an AGA eR7 is a user panel overheat: the electronics behind the top left door have measured too much heat. AGA's list of causes starts with the baking oven door left open or not closing properly and a door seal leaking heat.

What to do when 139 shows on the ovenKind of codeDoor and lock
The motorized lock did not reach the position the control asked for, or its switch reported the wrong one. Most often this shows during or after self-clean; the latch, its switches and the door's alignment are checked before the lock motor is replaced.

Before you book,
in this order.
Each step comes from AGA's own guidance for 139 on its ovens. Follow it to the end: the last card says whether this is a visit.
Make sure every oven door is fully closed and sits flush.
Take towels or cloths off the top left door and the handrail; AGA says they block the control vent.
Look for a worn or gapped seal around the baking oven door.
If 139 returns with doors shut and the vent clear, book a visit.

It usually turns into door lock and self-clean repair. Book with the code and the model number.
What not to do
139 is not a sign that an oven is overheating food. It is the control electronics that are too warm.
