What this means on these models
On the YAER oven this symptom is usually the self-clean cycle, which asks more of this cavity than anything else it does and is the first cycle to stop when something is marginal. The trailing letters in these model numbers mark finish and trim, not a different mechanism, which is why one ranking covers the whole family.
What you observe on these models
- The oven switches off after the same interval every time — That regularity is a timer obeying an instruction, not a component failing.
- Keys need a hard press, or a key repeats — A membrane fault, which can cancel a cycle without anyone touching the panel.
- The lock hums and reverses at the start of a cycle — The door is never confirmed, so the cycle has nowhere to go.
- Cycles fail at random with lights flickering elsewhere — The supply, not the oven — and the appliance is the victim rather than the cause.
- 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 YAER family
- Self-clean cycle aborting on its own protections — Ranked first on this family. Clean runs the cavity far hotter and for far longer, so a door seal, a lock or a limit that copes with baking will not cope with it.
- Thermal limit cutting the cycle as the cavity peaks — Next, and close behind it. Blocked ventilation and a fan that has stopped both produce it without any part having actually failed.
- Sabbath, demonstration or control-lock mode active — Next after those two. Control lock refuses inputs, demonstration mode runs the panel without heat, and sabbath mode suppresses displays and responses by design.
- Control board losing the cycle part-way through — Fourth, and the least likely of the four. A board that browns out mid-cycle drops back to the clock with no error, which reads to the owner as an oven that cancelled itself.
- Body: A brand-generic article on this symptom starts with the control board. Here the self-clean cycle moves ahead of it, because the models in the table share the same construction, so what is true of one is true across the family.
What to check first, and why that order
- Test whether ordinary bake cycles complete normally — Bake fine, clean aborting, is a different and much narrower problem than an oven that cannot complete anything.
- Check that the cooling fan runs and that the vents are not blocked — A silent cooling fan during a long bake explains a cycle that cannot survive its own heat.
- Check the panel for a lock, demo or sabbath indicator and clear it — If the oven behaves normally once cleared, there was no fault to diagnose.
Before any panel comes off
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 this becomes a service call
Write down the error code and the stage the cycle reached before calling; on these models that pair narrows the visit considerably. Call once the free eliminations are done — timers cleared, modes cleared, vents and cooling fan confirmed — because what remains is inside the console.
