What the customer reported
The oven stayed cold. Burners on the cooktop lit and ran normally, which is the pattern that usually points away from the gas supply and toward the oven's own controls.
What we found
With the oven calling for heat, the element drew no power. Working back from there, the thermostat was not closing the circuit — it had failed open, so nothing downstream ever got the signal to start.
What we did
Replaced the oven thermostat, then ran the oven through a full preheat cycle and checked recovery after opening the door, so we could see it hold a set temperature rather than just reach one.
Why this happens
An oven thermostat is a wear part. On a range that gets daily use, ten to fifteen years is a normal life, and the failure is usually abrupt: the oven works one week and is stone cold the next. The cooktop keeps working because it runs on a separate path.
