One JennAir explanation covers sixteen sensor-related displays: temperature sensor, control or wiring. A breaker reset is the owner step.
Model compatibility: JennAir reuses codes across series and model years, so 1D11, 1D12, 1D21, 1D22, 3D11, 3D12, 3D21, 3D22, F01, F02, F1, F1-1, F1-2, F1-H, F1-L, F3-1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
These codes may indicate a problem with the oven temperature sensor, the control, or the associated wiring.
JennAir applies one explanation to sixteen different displays. Each may indicate a problem with the oven temperature sensor, the control, or the wiring that links them.

The hyphenated five are on JennAir’s range page. The others are listed for ranges and wall ovens alike. Although they look different from the four-character numbers, the range page treats them identically; they are not separate faults with their own steps.
Why a sensor shows up here
For an oven to hold a set temperature, its control must know what the cavity is doing, and the sensor supplies that information. The sensor, the control and the wiring could each disturb that reading, which is why JennAir lists all three. Which one is responsible is not stated.
Steps to take
Turn the oven’s breaker off for sixty seconds.
Restore it.
Look at the display for one minute.
Confirm the oven runs.
Clearing the display in this way is everything the owner page asks.
Time for a call
If the code reappears, it is time to call. Sensors, controls and wiring are behind panels and the source offers no owner repair. A technician can test the sensor and its connections to the control.
Dial (310) 622-9465 for Los Angeles and have the code ready. Mention too if the oven had been baking too hot or too cool before the code appeared. The wall oven repair page has the particulars.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
