F102
AEG F102 on an oven: door not closed or electronics fault

Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On an AEG oven, F102 at switch-on may mean the door is not fully closed or there is an electronics problem. Close the door fully, isolate the oven for a few minutes and reconnect it; if F102 returns, book service.
Safety first
Stop and check this first
- If the safety switch or fuse trips again when reset, stop: there may be an electrical fault and a qualified electrician must check it.
- Do not force the door or take the lock apart; if the oven was in use, the glass and the inside can burn.
Safe checks you can perform
- Door fully closed
- Isolating for a few minutes
- Fuse or safety switch at the consumer unit
Leave these tasks to a qualified professional

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.
Door lock check
What they doWith the oven isolated, the AEG service engineer inspects the door lock mechanism and checks with their tools the signal the control receives.
They must show youthe state of the lock and the signal reading.
In writingwhat was checked, any part replaced with its reference and the reason.
Switch-on and locking test
What they doAfter the repair, the engineer switches the oven on several times with the door closed and, where the model uses it, runs a function that locks the door.
They must show youthe oven starting without F102.
In writingthe tests 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.
Door fully closed
- Who:
- you, with the oven cold.
- How:
- open the door, check nothing sticks out and that the door and its glass are correctly refitted if you cleaned them recently, and close it firmly.
- Result that matters:
- whether the door shuts properly and F102 clears.
- If something stopped it closing or it was refitted wrongly:
- correct it following the manual and switch on again.
- If the door shuts properly and F102 stays:
- go on to isolating the oven.
- Evidence to keep:
- photo of the closed door and the code.
Evidence: Oven displays code F102
Isolating for a few minutes
- Who:
- you, at the plug or the consumer unit.
- How:
- isolate the oven for a few minutes, unplugging it if the plug is reachable or switching off its breaker, then reconnect it, as AEG advises.
- Result that matters:
- whether F102 returns at switch-on.
- If it does not:
- it was a one-off; note when it happened.
- If it does:
- AEG says to contact its customer care to arrange a service visit.
- Evidence to keep:
- note of the time and the result.
Evidence: Oven displays code F102
Fuse or safety switch at the consumer unit
- Who:
- you, looking at the consumer unit without opening it.
- How:
- check whether the oven's fuse or safety switch has tripped and reset it if possible. If it trips again, do not keep trying.
- Result that matters:
- whether the circuit protection is fine.
- If it had tripped and now stays on:
- try the oven again.
- If it trips again:
- leave the oven isolated and consult a qualified electrician, as AEG suggests.
- Evidence to keep:
- note of which protection tripped and how often.
Evidence: Oven displays code F102

What it means
AEG explains that F102 shows when the oven is switched on and gives two possible causes: the door is not fully closed or there is a problem with the electronics. Its page adds that the door lock may be defective. The control checks the state of the door lock at start-up and warns if it is not as expected. The code alone does not prove the lock is faulty: a door that is not properly shut must be ruled out first. AEG says to close the door, isolate the oven for a few minutes and, if it returns, book a visit. The page is from AEG's UK support site; confirm the code in your model's manual.

Symptoms and causes
Probable causes · in order
- Door not fully closedCommon
AEG's first cause. Fits if something stops it shutting or the door was refitted after cleaning, and F102 clears once it closes properly.
Evidence: Oven displays code F102
- Door lockPossible
AEG says the door lock may be defective. Fits if F102 returns with the door properly shut after isolating the oven; the engineer confirms it.
Evidence: Oven displays code F102
- Electronics problemPossible
AEG's other cause. If the lock works and the code stays, the fault may be in the electronics; the service engineer checks it.
Evidence: Oven displays code F102
