What you are actually seeing
- The oven starts and stops immediately
- It works only when the door is pressed
- A blown house fuse or breaker at the same moment
- The oven went dead abruptly with no warning
- Not this fault: An oven that runs and does not heat
Ranked causes on a Contoure microwave
- Outlet, plug or supply — Ranked here because: a coach appliance can be fed from shore power, a generator, an inverter or the battery bank, and a supply that is present but weak produces faults that look like component failures
- Inverter, converter or coach supply not delivering — Ranked here because: the converter and the transfer switch sit between the appliance and whatever is actually powering it, and both fail in ways that look like a dead machine
- Internal line fuse blown — Ranked here because: the interlock is a safety device and the machine is designed to do nothing at all without it
- Broken door latch tab — Ranked here because: coach appliances are used intermittently and stored for months, which produces its own fault pattern
What to check, and in what order
- Inspect the plastic latch tabs on the door edge for cracks or a break
- Check the panel for a child-lock indicator and release it using the manual
- Try the oven plugged directly into a known-good outlet with no extension lead
- Try to start with the door pressed firmly closed
Steps you can safely do yourself
- Try the oven plugged directly into a known-good outlet with no extension lead — Tools: none — Estimated time: about ten minutes
- Try to start with the door pressed firmly closed — Tools: none — Estimated time: a few minutes
- Plug a lamp into the same outlet and confirm it lights — Tools: lamp or outlet tester — Estimated time: a few minutes
- Check the breaker and any GFCI outlet on the same circuit — Tools: none — Estimated time: a few minutes
- Inspect the plastic latch tabs on the door edge for cracks or a break — Tools: flashlight — Estimated time: a few minutes

When to call a technician
the outlet is confirmed good and the oven is completely dead, since that is an internal fuse and the reason it blew a latch tab or an interlock switch needs replacing the oven runs only when the door is held or pressed
