The short answer
There are two different door complaints on HBLP models and they have almost nothing in common. One is a seal that leaks heat and spoils results. The other is a door the control cannot confirm, which stops the cycle outright. On this designation the control decides whether anything heats at all, so the second is the one to settle first.
Two complaints, told apart
- The cycle stops when the door is touched — The confirmation is being lost as the door moves. This is the control complaint.
- The oven refuses to begin a cycle at all — Also the control complaint, at its other extreme.
- The cavity lamp behaves oddly with the door shut — On builds that tie the lamp to the door state, this reads the switch for you.
Ranked once the complaint is identified
- A door switch that has stopped reporting — It leads because it is the cause of the complaint that stops the appliance working, and because on this designation the control will not act on a door it cannot confirm. Intermittent switches produce the touch-and-it-stops version.
- A latch or catch out of adjustment — The switch can only report what the mechanism presents to it, and a catch that has drifted holds the door a fraction short of where it needs to be.
- The door seal — This is the whole of the other complaint. A hardened or displaced seal leaks heat and spoils results without ever troubling the control.
- Hinge tension — It sits behind both complaints: a door that hangs meets the frame unevenly, which leaks, and presents badly to the catch, which stops cycles.
- The control — Last, as on every page for this designation. It is condemned far more often than it fails, because everything above it produces symptoms that look exactly like a control fault.
Ask which complaint you have
- Ask first whether cycles run — Running cycles with poor results is the seal. Stopped or refused cycles are the door confirmation. Everything else follows from that answer.
- Watch the cavity lamp through a slow close — On the builds that tie it to the door, the lamp tells you what the control believes without any tools.
- Touch the door during a running cycle — A cycle that stops is conclusive, and it is a test you only need to perform once.
- Do the paper test cold, at several points — It settles the seal complaint independently of anything the control is doing.
- Clear timers and modes before condemning the control — A refusal explained by a setting is the commonest false alarm on these models.
Before you open anything
Safety
Touch the door gently to test a running cycle, and do not attempt to hold a door in position to keep a cycle going. Switch the oven off at its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Door switches and catches sit behind the frame and are matched to the control that reads them, which is why nothing on this page asks you to adjust one.
When to call a technician
Deciding which complaint you have, doing the paper test and watching the lamp are owner work and they route the call correctly. Switches, catches, hinges and the control are not. Call once you can say whether the oven runs cycles or refuses them — it changes the parts a technician brings.
