The short answer
On the ACR oven this symptom is usually the control board, because on this generation every cycle is a program the board is running and a board that resets abandons it silently. The ACR family splits across trim and finish suffixes rather than across different machinery, so the order below holds for every one of them.
What you observe
- The cycle stops and the panel returns to the clock — A clean reset with no error, which is the board or the supply rather than a sensor.
- The cycle stops and an error stays on the display — A component reported something.
- Clean aborts but ordinary baking is fine — A margin problem in the door, lock or ventilation rather than a break.
- The oven switches off after the same interval every time — That regularity is a timer obeying an instruction, not a component failing.
- NEAR MISS — the cycle runs to the end but nothing ever gets hot — A cycle that completes without heat is a heat-path fault and belongs on the not-heating page.
Causes, most likely first on the ACR family
- Control board losing the cycle part-way through — First on this family. It leads here because the pattern — different cycles, different times, always the same ending — fits nothing else on the list.
- Temperature sensor out of range and aborting the program — Second on these models. An open or short in the sensor circuit is the one fault that the control is designed to react to instantly, so the cycle dies rather than drifting.
- Touchpad or membrane registering presses on its own — Third. The tell is a key that needs a hard press, a key that repeats, or a cycle that changes mode rather than simply stopping.
- Supply interruption or a brown-out at the socket — Last of the four, and the one to reach for only when the others are clean. Long bakes and clean cycles run for hours, which gives the supply many more chances to interrupt them than a short cycle ever gets.
- Body: A brand-generic article on this symptom starts with the control board, and so does this one. What changes below it is the order: the temperature sensor out of range and aborting the program moves up on these models, because the variants here differ in finish rather than in mechanism, so one subsystem carries the whole family.
Check in this order, and why
- Note whether the panel returns to the clock or holds an error when the cycle stops — A clean return to the clock is a reset.
- Note whether the abort happens at the same point in every cycle — An abort that always lands at the same temperature stage points at the sensor circuit rather than at the board.
- Press every key in turn and note any that are dead, stiff or repeating — One misbehaving key among many is the membrane; a whole panel that does nothing is not.

Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off.

When to call a technician
Call once the free eliminations are done — timers cleared, modes cleared, vents and cooling fan confirmed — because what remains is inside the console. Call rather than repeat a clean cycle that has aborted: running it again drives the same overheat that stopped it.
