What causes the F3 E1 error code?

On double oven models, the lower baking cavity has its own temperature sensor that’s separate from the upper oven. This sensor in the lower oven sends information about how hot the cavity is to the control board so that the board can control the temperature.

In general, F3 codes typically indicate a communication problem between the oven sensor and the control board. The E1 specifically refers to a problem with the lower oven sensor readings. If your oven has lost touch with the lower oven sensor, it can’t maintain the right baking temperature.

The F3 E1 error might show up due to:

• Loose or damaged sensor wiring connections
• A malfunctioning lower oven temperature sensor
• Issues with the oven control board

Keep safety first

Your safety should always be the top priority when performing any appliance repair.

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by preventing any risk of electric shock.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can clearly see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.

How to troubleshoot an F3 E1 error

Step 1 – Inspect the lower oven sensor wiring

1. Make sure the oven is turned off and unplugged from the power supply.
2. Remove the top access panel on the oven.
3. Find wiring harness connector P2 for the lower oven sensor (you can check the oven’s tech sheet to find more specifics for your model).
4. Check that P2 is firmly plugged into the oven control board.
5. Make sure there’s no wire damage between P2 and the sensor. Reset any loose plugs and/or immediately replace frayed or pinched wires.

If the wiring checks out OK, you can move on to resistance testing.

Step 2 – Check sensor resistance

You need to test the electrical resistance across the lower oven sensor.

1. Set your multimeter to measure resistance in Ohms (symbol Ω).
2. Disconnect the sensor wiring from the P2 connector.
3. Touch the multimeter probes to the corresponding wires/pins.
4. Check the resistance reading on the multimeter display.

At room temperature (about 70°F), you should get a reading somewhere around 1080 ohms. Your oven’s owner manual will specify the acceptable Ohm range for your particular model.

If the sensor’s resistance is way outside the expected range, that means your main oven sensor is faulty and will need to be replaced.

Step 3 – Replace the main control board

If there are no wiring problems and the lower oven sensor checks out OK, you can replace the main control board as a last resort.

Once you replace the board, you’ll need to replace all the panels, restore power, and run a short test bake cycle to see if the F3 E1 error clears.
