Aeg santo 1688 fridge power/light flashes when door open

You have very good door-seals,
with strong magnets on the refrigerator.
I suspect, You must pull hard to open the door.

Does the fridge have 2 wheels?
It may only stand firm on 2 "legs" and not 4.
This problem is the first, I ever heard,
I do not know this model,

If it is a Refrigerator that is not very heavy, this can happen.
When the door seals are very good, what can happen is

The door has been closed and the air inside the fridge becomes cooler and cooler.
The air inside the food-compartment contracts,
because it cools down and pulls even more on the inside of the door surface, actually pulling the door shut.
( a negative air-pressure inside the fridge) compared to
the outside of the refrigerator.

A trick I am using is,
1.)
I place my finger between the door and the cabinet-frame.

2.)
Then, with the finger, index or middle finger,
I push gently
against the Door-Seal (Gasket).
for 1 or 2 seconds,
This allows the Air from outside, (higher pressure)
to flow into the food compartment of the fridge
and now it is easy to open the door.

Let me know if this works for you.
Appreciate to be alive and be kind to others.

replace the door seals
make sure that the door closes properly
turn the fridge setting up to 5 or 6

Usually this is a symptom of a faulty door seal or a very frequently opened fridge they extra moisture load from the environmental air.

the trouble is coming from eithier the micron switch located at the backof the paddle,or the auger motor.It is the motor that rotates when you press the cube dispenser lever located at the back portion of the icebucket,it might got stucked.or its winding is open Try to hve a check ,first open the freezer door, pull out the icebucket, look fr the light switch then maintain the door open,use your right hand in pressing the switch to simulate a closed door position,next use your left hand to press the cube dispenser lever, if the auger motor rotates and you heard a humming sound, it means it is only your ice cubes that sticked together preventing the motor to rotate freely,or there is something wrong with your bucket only,if your hear humming sound only, the auger motor is stuck up, unplug the unit, removed all the screws securing the bracket,disconnect the wiring connector, pull out it out,try to thaw the froozen motor if it is still stuck,wait a longer more or try to apply wd40 oil in between the entangled rotor and core, lubricte.If you hear nothing the winding might be open or there is no supply to the motor., point of check- micron switch- check for continuity,wiring leading to it and the line goin out to cabinet/inside, check the main connector to the bucket area for corrosion or accumulated dirts, And lastly if you are not confident enough to do the job sir better to calla qualified technican to do the troubleshooting sir, safety is our first priority.

as rwsummers correctly points out replace this part as from uk i bought it from maplins £3.31 part no N74CN 1UF 275V de-solder the two points on rear of pcb and re-solder new part in place and reassemble turn on power and "voila" works like new. Thanks.

Had the same problem. I'd already tried waggling the drain rod from inside the fridge but to no avail. I pulled out the fridge and pulled off the 'top hat' end on the very end of the corrugated drain pipe. Inside was pretty gunky.
Just clean it thoroughly especially around the little rubber mushroom and the problem goes away. Simples

Check the damper between the fridge and freezer. It may be broken or frozen open. If this happens and you have a water reservoir in the fridge then it could freeze and crack - leak and then flood your house... Shut off the water supply until you get the problem fixed.

hi tracy, think its possibly better getting a repair guy in as this fault is not streight forward. possibly a fault in the defrost circuit, or freezer fan not functioning, or possibly a leak in the system. all theese areas need testing equiptment.

Did you ever get any advice for this problem? Please repost if not.
