The short answer
On HEI models the control and the arrangements around the door explain more cycle faults than the heating parts do. A lock that has not returned home, a door the oven cannot confirm, or a cleaning state that never cleared will all prevent a cycle, and all three look identical from the front: an oven that simply will not go.
What the door side looks like
- The oven will not begin a cycle at all — The panel responds and nothing follows it.
- The door lock is engaged when it should not be — Visible or audible depending on the build, and conclusive when it is.
- A cleaning state appears not to have cleared — It locks out ordinary cooking by design until it does.
- A cycle stops if the door is touched — The oven is losing its confirmation as the door moves.
- A motor or mechanism sound at the door with no result — Something is trying to move and is not arriving.
Door and control causes, ranked
- The lock mechanism not returning home — It leads because it is the single commonest reason an oven of this kind refuses everything, and because the appliance will not compromise on it: until the lock reports where it should be, nothing runs.
- A door the oven cannot confirm — Separate from the lock. The oven checks the door as well as the lock, and a switch that has gone intermittent stops a cycle when the door is disturbed rather than at the start.
- A cleaning state that has not cleared — Free to establish and common after a cleaning cycle that was interrupted. It is the cause most often mistaken for a failed control.
- The control — Fourth, and only after the three above. On this build a control is condemned far more often than it deserves, because everything above it produces the same symptom.
- The heating parts — Last on this page deliberately. An element or a sensor fault usually spoils a cycle rather than preventing one, so it is not where a never-started oven is diagnosed.
Settle the door before anything else
- Look and listen at the door lock — Whether it is engaged, and whether it tries to move when a cycle is requested, decides most of this page.
- Let any cleaning state finish or cancel it as the appliance intends — Then wait for the lock to release on its own rather than helping it.
- Open and close the door firmly and request a plain bake — It separates a door confirmation fault from a lock fault in a moment.
- Note whether a running cycle stops when the door is touched — That is the door rather than the lock, and it is a different part.
- Clear timers and modes before condemning anything — A delayed start explains a refusal completely and costs nothing to rule out.
Before you open anything
Safety
Never force a door lock, and never attempt to release one mechanically while a cleaning state is active — the lock exists because the cavity reaches temperatures that make an open door dangerous. Switch the oven off at its breaker before removing any panel, because a capacitor can hold a charge after the power is off. If the lock has jammed with the door shut, leave it and call.
When to call a technician
Looking at the lock, clearing a cleaning state, working the door and clearing timers are owner work. The lock mechanism, the door switches and the control are not, and a jammed lock in particular is a call rather than a project. Call once the door has been worked, the state is clear, and the oven still refuses a plain bake.
