Start here
An oven on the AN line that stalls mid-programme is usually protecting itself or waiting on a door. The model matrix on this page lists two model numbers under this family badge. When the stop happens tells you which: an early stop is a precondition, and a late stop is heat management.
Where the programme stops
- The programme starts and stops within minutes — A programme that dies in the first few minutes, before the cavity has had time to get anywhere near temperature.
- The door lock cycles and will not release — A lock that runs and never confirms stops the programme and leaves the door held.
- The cavity never reaches the set temperature — Long preheats and food that never browns point at heat input or at how the cavity is being measured.
- The display shows a stalled countdown — Programme time only advances once the set temperature is reached, so a stuck timer is a preheat that never finished.
- The cooling fan runs on for a long time or not at all — A cooling fan that has stopped is the commonest cause of a thermal cut-out ending an otherwise healthy programme.
- NEAR MISS — the oven is completely dead — That is a supply or control-power fault and it belongs on a different page; this one assumes the programme starts.
Causes, most likely first on the AN line
- Cooling fan stopped or vents obstructed — Ranked first on the AN line because the matrix on this page covers only a handful of closely related models — a built-in cavity depends on its cooling path to protect the controls, and a blocked or stopped fan ends programmes that are otherwise perfect.
- Thermal cut-out opened and needs resetting — Second: the consequence of the cause above, and it is what actually stops the programme.
- Door latch or switch not confirming — Third: a precondition failure, and it stops the programme early rather than late.
- Element, sensor or control fault — Last, and the point at which the diagnosis stops being observational.
The check order on these models
- Listen for the cooling fan and check every vent is clear — First because the cooling path protects the controls, and a blocked or stopped fan ends otherwise healthy programmes.
- Let the appliance cool right down and run the programme again — A repeat stop at the same point confirms a thermal cut-out rather than a control fault.
- Close the door and listen for the latch and switch — Close the door and listen for the latch and switch, which stops a programme early rather than late.
- Check the cavity reaches temperature at all — Check the cavity actually reaches temperature, with the thermal path and the door already excluded.
Before any panel comes off
Safety
Switch the oven off at its breaker and let it cool before working; a capacitor can hold a charge after the power is off. Do not tape or wedge a door switch to force a programme, and do not run the appliance with any panel removed. On a gas model, any smell of gas means leaving the building and calling from outside rather than investigating.

When to call a technician
The condition on these models is whether the fix is in front of the cavity or behind it. Settings, vents, door closure and observation are owner work. A latch assembly, a cavity sensor, an element or an igniter means the appliance is opened, and on a built-in cabinet that usually means it comes out of the housing first.
