JennAir Oven: not functioning
What is this symptom?
Is your Jennair oven not functioning? If your oven is unresponsive, with no display or heating, you may be facing power supply issues, a locked control panel, or a failing electronic control board. Understanding these common causes can help you troubleshoot effectively.
Important Tips for JennAir Models
- Control lock and demo mode can cause the oven to appear non-functional until disabled
- Electronic control board failures are reported as the most common repair cause
Possible Causes
Power supply issues (breaker/fuse/tripped circuit)
How to Identify: Oven has no display, no lights at all; household circuit breaker has tripped or fuse blown

Control lock or demo mode engaged
How to Identify: Display may show "Control Lock" or be unresponsive until lock is cleared; demo mode showing features instead of normal operation
Part: Oven control panel settings
Electronic control board failure
How to Identify: Oven remains dead even with power; error codes may be displayed; no heating or functions if board fails
Part: Electronic control board
Faulty heating elements / igniter (if power but no heat)
How to Identify: Oven powers on but does not heat; elements may look damaged or igniter does not glow/ignite
Part: Heating element (electric) or igniter (gas)
Faulty thermostat / temperature sensor
How to Identify: Oven may power on but fails to regulate temperature or reach set temperature; inconsistent heating
Part: Thermostat / temperature sensor
