Whirlpool Oven Error F3 – Oven Temperature Sensor Fault
The control can't get a valid reading from the oven temperature sensor, so it won't heat the oven.
Safety first · Consult a professional
Switch off the breaker or unplug the range before removing the sensor, and let the oven cool completely – the probe and back wall stay hot long after the display goes dark. On a gas range, the sensor swap involves no gas parts; if you smell gas at any point, leave the house and call your gas utility from outside.
- Gas appliance: no DIY repairs. If you smell gas, leave the building, do not use switches and call your gas utility’s emergency line from outside.
- Unplug the appliance or switch off the breaker before opening any panel. Mains voltage can kill.
- Hot surfaces and hot water can cause burns. Let the appliance cool down first.

Whirlpool ranges and wall ovens use a thin probe (an RTD sensor) at the upper back of the oven cavity whose resistance rises as the oven heats up. The control reads that resistance constantly; when it drops to near zero (shorted) or disappears (open circuit), the control can't regulate temperature and shows F3. On newer controls a suffix tells which: F3-E0 or F3-E1, depending on model, for an open or shorted circuit. The sensor itself is the usual culprit, followed by a heat-damaged plug behind the back wall. It's one of the more straightforward oven repairs for a careful DIYer. The same code system appears on Maytag and KitchenAid ranges built by Whirlpool.
How it looks on the display
Model families & display variants
| Model family | Shows | Note |
|---|---|---|
| Newer electronic controls | F3-E0 | The E suffix identifies whether the sensor circuit reads open or shorted; F3-E0 and F3-E1 both lead to the same checks. |
| Older electronic controls | F3 | No suffix; the same sensor test applies. |
| Maytag and KitchenAid ranges built by Whirlpool | F3 | Same code family and the same sensor location at the upper back of the cavity. |
Symptoms
- F3 or F3-E0 / F3-E1 on the display with beeping
- Oven won't preheat or shuts off shortly after starting
- Cooktop burners still work while the oven is locked out
- Code appears after a self-clean cycle or after the range was moved
- Oven temperature swings wildly before the code appears
Possible causes
Ranked by how often each cause is behind this code (editorial estimate).
- Oven temperature sensor failed open or shorted
- Heat-damaged or loose connector where the sensor plugs in behind the oven
- Sensor wire pinched or chafed behind the range (often after moving it)
- Sensor probe bent and touching the oven wall or element
- Control board input for the sensor has failed
Fix it step by step
Power-cycle once
Turn off the breaker for the range for 5 minutes, then restore power and start a bake at 350°F. A code that reappears within a few minutes is a genuine sensor-circuit fault, not a glitch.
Look at the probe
Open the oven and find the thin metal probe at the upper back of the cavity. It should stand straight and not touch the wall or the element. A bent, blistered or broken probe needs replacing.
Tools: Flashlight
Pull the sensor and check the plug
With the power off and the oven cold, remove the two screws holding the sensor mounting plate and gently pull it into the cavity until the connector shows. Look for melted plastic, discoloration or loose pins, and reseat the plug firmly.
Tools: Screwdriver, Flashlight
Measure the resistance
Unplug the sensor and measure across its two terminals. At normal room temperature (about 70–75°F) a good sensor reads roughly 1,080–1,100 ohms. OL means open, a reading near 0 means shorted – both call for a new sensor.
Tools: Multimeter
Wiggle-test the wire
While the meter is connected, flex the sensor lead along its length. If the reading jumps or drops out, there's a break inside the wire even though the probe looks fine – replace the sensor.
Tools: Multimeter
Install the new sensor and test
Plug in the replacement, tuck the connector back through the hole and fasten the plate with its screws. Restore power and bake at 350°F with an oven thermometer on the middle rack to confirm the temperature is close to the setting.
Tools: Screwdriver
How to reset F3
- Press Cancel to silence the alarm
- Turn off the range's breaker for 5 minutes, then turn it back on
- If F3 appears again once the oven starts heating, the sensor circuit still has a fault

When to call a technician
Call a technician if a new sensor measures correctly but F3 keeps coming back – the control board input or the wiring harness is then at fault. Also get professional help if the range is gas and you'd need to pull it away from the wall, since the gas supply line must not be strained or disconnected by an untrained person.
Frequently asked questions
Can I still use the cooktop with an F3 code?
On most ranges the surface burners or elements keep working, because only the oven's temperature control is locked out. If the whole range is dead, the problem is bigger than the sensor.
What's the difference between F3-E0 and F3-E1?
Both point to the oven temperature sensor circuit. One indicates an open circuit and the other a short, depending on the control generation; either way you test the sensor and its connector first.
Do I need to pull the range out to change the sensor?
Usually not. The sensor comes out through the back wall of the oven cavity and the connector pulls through with it. Only a damaged harness further back requires moving the range.
Why did F3 appear right after self-clean?
Self-clean pushes the sensor and its plug to their highest temperature. An aging sensor or a weak connection often fails exactly then.
