Things have been progressing slowly due to the winter lurgi which seems to
have hot everybody over the holidays.
I now have the cooker hood main unit off the wall, but I haven't fully
taken it apart yet because it is covered in several years of grease.
I can now see inside it properly, and it has a capacitor along side the
motor. The bits I can see are labelled
2uF +/- 5%
50/60 Hz A/C
A quick search shows that these are common for fans of all sorts.
I have no idea if this is the problem, but I was wondering what function
the capacitor serves.
Initial searching suggests that it is a run capacitor not a start
capacitor because of the 2uF/450V rating. Also, the fan is only 140W so I
am guessing it doesn't need a boost to start spinning.
The extractor hood is about 5 years old; how long do capacitors normally
I'm wondering about the advisability of testing (if I can) or just
replacing. The capacitor is about £12 but the whole motor assembly is
In a day or so I should have most of the grease off and the fan motor and
wiring extracted from the hood so that I can do a little testing and
Recap of problem.
Buttons for 3 fan speeds seem to work - power indicator in control panel
goes on and off.
Fan doesn't work at any speed.
Now I have access, the fan spins freely when flipped with a finger.
The layout is power cable -> switch panel -> wiring box on side of motor.
Wires to the lights and capacitor come back out of the wiring box.
First question is how you test that the capacitor is working?
