Noisy cooling fan Moulinex microwave

[Adrian Glaubitz]

Hi,

a friend of mine has an older microwave oven (Moulinex Y87 Optimo Duo)
whose cooling fan has started to be very noisy and vibrating. I have
checked the European parts distributor EURAS already and they list the
fan as NLA.

Anyone knows here, what kind of cooling fan these ovens usually employ
so I might look for a cheap replacement fan (voltage, power consumption)
? My friend has moved to Norway, he just graduated and thus doesn't
have the money to buy a new microwave oven, especially in Norway
(expensive) .

I am in Germany and could buy one for him, so if anyone could give me a
hint what to look for, I'd highly appreciate it. In the meantime, he is
going to disassemble the oven to inspect the fan.

Regards,

Adrian

Fasco makes small fractional HP ac motors but you need the
specifications both electrical and physical.- Hide quoted text -

Why not lubricate the fan bearings? Much easier and cheaper than
replacing the whole fan. Sometimes slightly bending the sheet metal
holding the sleeve bearings will also solve the problem, along with
lubrication.

Hi!

a friend of mine has an older microwave oven (Moulinex Y87
Optimo Duo) whose cooling fan has started to be very noisy
and vibrating.

If the fan still runs, there is a good chance you can fix it. It will
be vibrating for one reason:

1. It's loose.
2. A blade is broken.
3. The bearings are cheap, dry or both.

1 and 3 are the easiest ones to fix. You can tighten the fan or oil
the bearings.

Reason 2 will require some fabrication or reattachment of the broken
blade, as well as a solution to whatever made it break. It will also
involve rebalancing the fan if you find that it runs noisily after
repair, and to prevent excessive wear on the bearings.

Most of the motors are fairly simple AC powered shaded pole units. A
truly dead microwave oven could provide a replacement if one is
required. As long as the operating voltage is correct, and you can
figure out a way to mount the new motor, there should be no problem.

Thanks for the comprehensive information. We're now just having another
problem first: the fan is hardly accessible, he said he would have to
disassemble the *whole* oven to access it, not very service-friendly. I
don't know then whether he will actually do it or live with the problem
until he can afford a new one. I keep trying to convince my friend.

Thanks alot,

Adrian
