Hi all,
Just found this forum, looks like there is a lot of great advice on here.
I need some help wiring up a Fime motor in my AEG cooker extractor fan. I bought a new motor, installed it into the unit correctly, wired it up matching the colours from the old one… tested it, and nearly set it on fire.
It seems the new motor and old motor wire colours don’t correspond.
Here is a diagram of the coloured wires coming from the motor, and the switch some of them need to go in. The switch has some links from one point to another as noted on there.

Neatly drawn diagram by me:

Would love to know what to test with the multimeter and then how to know which wires from the motor go where. Any advice greatly appreciated.
Many thanks
Mark

Hi Dave,
Appreciate the reply.
Model number of the hood is: AEG DL7275-M9
PNC: 942 122 593Thank you for this. Very helpful. I believe that is how it was wired up to the original motor, however, the replacement motor colours don’t match exactly with the original, I tried wiring up the same and nearly blew it up. There is an extra grey wire too. I would love to know what multimeter tests I could do to find out which are the correct wires that need to go into each switch point to be sure. Any idea how I could do that?
Thanks
they give no info re motor colours change
correct motor part no is showm as 5028 58 72-00 / 3
what colours match and what dont
what is wrong with old motor ?
Dave
Hi Dave,
The new motor has a grey wire too (that had a crimp on it). 7 wires in total.
Old motor non responsive, I stripped it and put it back and still didn’t work so assume something in the coils has burnt out. Switch working fine.
When I wired up the new motor with the same colour wires, the motor turned on at Switch Position 1, and nothing at 2 and 3. Ran it on 1 for about 15 seconds and burning smell started, so turned it all off.
Sure my new motor is correct? They look identical, but apart from one extra wire.
If I knew how to test a 3 phase motor with a multimeter then I could work out which wire needed to go where. Any idea how to do that?
Thanks again
Mark
“Sure my new motor is correct? They look identical, but apart from one extra wire”
then it may not be correct just because it fits as they make different models but may use same chassisit wont be 3 phase. a 3 phase motor would only have 3 wires
Dave
This is the motor…

So difficult finding info about which wires are for what….
Would this not be called a 3 phase motor then? 3 speed motor instead?
Thank you for your continued advice.
Mark
its not 3 phase. a three phase motor would have to have a variable frequency supply to be able change speed
its a multi speed motor
first contact the supplier and get them to contact manufacturer. You need to know if there has been a mod since your unit was produced as the motor are clearly different
next i would do resistance tests between all wires to see waht you get. I am looking for one wire that has a higher resistance to all the others
bit of a long shot
Dave
Yellow – Blue is the highest of all the pairings, 130 compared to the next highest of around 115.
But anything connected to blue gives the highest readings. What does that indicate?
