On the covered Whirlpool range, 3D11, 3D12, 3D21, 3D22, F01, F02, F3 E0, F3 E1, F3 E2, F3 E3, F1-1, F1-2, F1-3, F1-H, F1-L, F3-1 means the oven temperature sensor is open, shorted or out of range First, unplug the range and look at the wiring to the sensor in the oven cavity.

Likely causes of “Whirlpool range code 3D11, 3D12, 3D21, 3D22, F01, F02, F3 E0, F3 E1”, and how to tell them apart
- 1
An oven temperature sensor that is open or shorted
What separates it The oven will not heat or the temperature is wrong
How to confirm A technician reads the sensor's resistance
- 2
A sensor wire that is loose
What separates it The code comes and goes
How to confirm Look at the connector at the back with power off
- 3
A sensor out of range
What separates it The oven overheats or underheats
How to confirm Compare with an oven thermometer
- 4
A control that misreads the sensor
What separates it A good sensor still gives the code
How to confirm A technician tests the control
- 5
Older F01 and F02 codes
What separates it The same fault in an older style
How to confirm The same checks apply

0 of 12 completedWhat to do first
ReversibleUnplug the range and look at the wiring to the sensor in the oven cavity.
Correct only the documented fault domain
ReversibleMeasure the sensor with a meter and replace it only if it is out of range. A power reset is the whole of what Whirlpool publishes for this code: remove power for 1 minute, restore it, and watch whether the code returns.
Reset and retry once
ReversibleWhirlpool's F3 E0 range page names the oven temperature sensor, the control or the wiring and gives a one-minute breaker reset; a one-off clears, a repeat needs the checks below.
Check the sensor wiring
ReversibleThe tables say to disconnect power or unplug the range, reconnect the oven temperature sensor harness if it is loose, and replace the harness if it is damaged.
Measure the sensor
ReversibleWith the range unplugged and the sensor disconnected, measure its resistance with a volt/ohm meter. The range tables say it should measure 1080 ohms at room temperature (70 degrees Fahrenheit); if it does not, replace the oven temperature sensor. Two other repair sources give the same 1080 ohm figure.
Replace the control last
ReversibleIf the sensor resistance and the harness are okay, the tables say to replace the electronic oven control.
Reset the power
ReversibleBreaker off for one minute.
Preheat to 350
ReversibleNote how long and whether it stops.
Compare temperatures
ReversibleUse an oven thermometer.
Look at the probe
ReversibleWith the oven cold, check it is straight.
Record the code
ReversibleWith the model number.
Book service
ReversibleIf it returns.
Model-specific
What is true of this model and not of its siblings
- Part
- Oven temperature sensor.
- Whirlpool guidance
- Reset, then service.
Stop boundary
When this stops being a self-service repair
- !Let the oven cool and turn off the breaker or unplug the range before you touch the sensor, since the oven is hot and the harness carries a signal from a live control
- !Do not bypass the sensor or tape the connector; an oven without a working sensor can overheat
- !If the code returns after a reset, book Whirlpool service with the model number and the code
- !Stop using an oven that overheats
- !Do not bypass a sensor

Exact questions
Common questions
What does 3D11, 3D12, 3D21, 3D22, F01, F02, F3 E0, F3 E1, F3 E2, F3 E3, F1-1, F1-2, F1-3, F1-H, F1-L, F3-1 mean on a Whirlpool range?+
the oven temperature sensor is open, shorted or out of range
Is the sensor the usual fix?+
It is the first part the tables name; the control is the last.
What does the temperature sensor code mean on a Whirlpool range?+
The oven temperature sensor is open, shorted or out of range.
Is the newer sensor code style the same fault?+
It is the same family in a different code style.
Can I replace the sensor myself?+
On many ranges it is a simple part, with power off.
Why does the oven run hot?+
A sensor reading low makes the control add heat.
Where is the oven sensor?+
A thin metal probe at the top rear of the cavity, connected by a wire to the control. It reads the temperature and sends it to the control.
Why does the oven overshoot?+
A sensor reading too low makes the control heat longer, so the oven runs hot and may burn food.
What is the usual cost?+
The probe is one of the cheaper oven parts, and the cost is mostly the visit.
Can I test it?+
A technician measures its resistance at room temperature and compares it with the service table.
Is a reset worth trying?+
Yes, once, but a code that comes straight back means a part has failed.
