On the covered JennAir range, F01 means the control reports a fault in the oven temperature sensing group First, cool the range and cycle the breaker to see whether the code clears. Then: check the oven sensor and its wiring with the power off, and have a technician replace the sensor or the control if F01 returns.
Differential
Likely causes of “JennAir range code F01”, and how to tell them apart
- 1
The control reports a fault in the oven temperature sensing group
What separates it The oven shows F01 and heats poorly or not at all
How to confirm Cool the range and cycle the breaker to see whether it clears
- 2
The oven temperature sensor reads open or shorted
What separates it The sensor wire at the back wall of the oven looks damaged
How to confirm With the range off, look at the sensor and its wiring
- 3
Wiring to the sensor loose
What separates it The code appears after the oven was cleaned or moved
How to confirm Check the connector behind the panel
- 4
A control board fault
What separates it The sensor reads correctly and F01 stays
How to confirm A technician checks the board
- 5
A one-off glitch
What separates it F01 appears once and clears after a reset
How to confirm Run another bake after the reset
Before you touch a setting
Record this first — changing settings destroys the evidence
- That the code is F01 and not F1
- What the oven was doing when it appeared
- Whether the oven heats and reaches temperature
- The model number from the frame

Reversiblecool the range and cycle the breaker to see whether the code clears.
Correct only the documented fault domain
ReversibleCheck the oven sensor and its wiring with the power off, and have a technician replace the sensor or the control if F01 returns. A power reset is the whole of what JennAir publishes for this code: remove power for 1 minute, restore it, and watch whether the code returns.
Cool the range
ReversibleLet the oven and the cooktop cool fully.
Cycle the breaker
ReversibleSwitch the range off at its breaker for a minute, then on.
Look at the sensor
ReversibleWith the power off, check that the oven sensor probe is not touching the wall and its wire is not damaged.
Run a test bake
ReversibleBake at a moderate temperature and watch whether F01 returns.
Check against a thermometer
ReversiblePlace an oven thermometer inside to compare with the display.
Book service
ReversibleIf F01 returns, a technician measures the sensor and the wiring before replacing the control.
Model-specific
What is true of this model and not of its siblings
- The code on this page
- F01, an oven temperature sensing fault.
- Parts involved
- The oven temperature sensor, its wiring and the control.
- Related
- 3D11 and F3 E0 describe the same group on other displays.
Stop boundary
When this stops being a self-service repair
- !If F01 returns after a reset, book JennAir service with the model number
- !Do not use the oven if it does not control its temperature
- !Cut power at the breaker before anyone touches the wiring

Exact questions
Common questions
What does F01 mean on a JennAir range?+
the control reports a fault in the oven temperature sensing group
Is it the same as F1?+
They are written differently and belong to different groups on some models, so match the display exactly.
Will a reset fix F01?+
It may clear a one-off, but a repeat points to a part.
Can I use the cooktop?+
The cooktop usually works, but avoid using the range until it has been checked.
Is the sensor expensive?+
A temperature sensor is a modest part.
What does the oven temperature sensor look like?+
It is a thin metal probe, about the width of a pencil, that sticks into the oven from the upper rear wall. With the oven cold and the power off, check that it is not bent against the wall and that its wire is not chafed; a technician measures its resistance with a meter.
