F111
AEG F111 on an oven: food probe faulty or not connected
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
On an AEG oven, F111 (also F11 or F129) usually means the food probe is faulty or not connected correctly. Remove the probe, plug it fully back into its socket and check the cable is not damaged.
Safety first
Stop and check this first
- Burn risk: the probe and its plug heat up with the oven. Unplug it with oven gloves or wait for it to cool.
Safe checks you can perform
- Reconnecting the probe
- State of the probe and its cable
- About 30 seconds off
Leave these tasks to a qualified professional
- Do not attempt this professional task: Probe socket and wiring check
- Do not attempt this professional task: Test with the probe in use
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Probe socket and wiring check
What they doWith the oven isolated, the engineer inspects the probe socket and tests the wiring to the control with a multimeter.
They must show youthe state of the socket and the wiring measurement.
In writingwhat was measured, any part replaced with its reference and the reason.
Test with the probe in use
What they doAfter the repair, the engineer connects the probe and runs a function that uses it, checking the oven shows the temperature with no code.
They must show youthe probe temperature on the display, without F111.
In writingthe test done and the result.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Reconnecting the probe
- Who:
- you, with the oven cold or wearing oven gloves.
- How:
- remove the probe from its socket in the oven and plug it back in, making sure the plug goes fully in, as AEG advises.
- Result that matters:
- whether the code clears with the probe properly connected.
- If it clears:
- it was not plugged in properly.
- If it stays:
- inspect the probe.
- Evidence to keep:
- photo of the connected probe and the code.
Evidence: Oven displays error message F11 / F111
State of the probe and its cable
- Who:
- you, no tools.
- How:
- look along the whole cable and at the plug: check for cuts, crushed or burnt sections, bent contacts or wear.
- Result that matters:
- whether the probe has visible damage.
- If it is damaged:
- stop using it; AEG says to replace it with a new one.
- If it looks fine:
- switch the oven off for about 30 seconds.
- Evidence to keep:
- photos of the cable and plug.

About 30 seconds off
- Who:
- you, at the oven's mains switch or the consumer unit.
- How:
- switch the oven off at the mains for about 30 seconds and switch it back on, as AEG advises.
- Result that matters:
- whether F111 returns with the probe connected.
- If it does not:
- no engineer needed.
- If it returns, even with a new probe:
- book an AEG engineer visit.
- Evidence to keep:
- note of what you tried and the result.

What it means
AEG explains that F111 usually indicates the food probe (roasting thermometer) is faulty or not connected correctly, and that on some models it shows as F11 or F129. The oven reads the food's temperature through that probe; if it gets no valid signal, it warns. AEG says to reconnect it, check cable and contacts, switch the oven off at the mains for about 30 seconds and, if the code stays after reconnecting or replacing the probe, have an engineer inspect the socket, wiring or control. The code does not prove the probe is broken. The page is from AEG's UK support site; confirm the code in your model's manual.

Symptoms and causes
Probable causes · in order
- Probe not plugged in fullyCommon
Fits if the plug did not go fully into the socket; AEG says to remove and reconnect it, and the code clears.
Evidence: Oven displays error message F11 / F111
- Damaged probePossible
Fits if you see a crushed or burnt cable, bent contacts or wear. AEG says a damaged probe should be replaced.
Evidence: Oven displays error message F11 / F111
- Socket, wiring or controlPossible
