Squeeeeeeaky oven fan

[Keith]

We have a 2 year old Indesit fan assisted double oven.

Lately, the fan has been really squeaky (only when the oven gets
really hot).

I can see 4 screws to remove the plate in front of the fan, so I can
get at it easily enough.

I'm thinking about trying to lubricate it to de-squeak it, but I'm not
sure what to use....presumably a standard lubricant like WD40 would
make food cooked in the oven afterwards smell like.....WD40. Which
would be bad.

Any good ideas?

Cheers,
Keith.

WD40 is not a good lubricant (for anything)

Use a Molybdenum grease if you can - if the bearings are too hard to get at
then use oil to soak into the sintered metal bearings. I think you will find
the motor is behind the oven. You will need to remove the front plate to
remove the fan and access the screws that hold the motor.
Are you able to check if the noise is the motor and not the fan binding on a
panel?

A fan hitting a panel is likely to sound more like a rattle. Mine did.
Worth checking though. You'll see signs of abrasion if its been doing it
for a while. Mine needed a change in a washer to alter its position. The
rear panel might have been bent through bumping by a heavy pan or casserole.

When ours started to do this, it turned out to just be the fixing bolts
which had vibrated loose, allowing the blades to just touch the
surrounding metal at certain temperatures.

If the fan uses sintered bearings (which run on a film of oil) applying
grease will just clog the bearing up

If it runs on ball races, it depends on how badly worn the bearings are

Really, which ever, the bearings should be replaced (assuming that the
shaft hasn't been taken out too)

I think the main point is that the motor and bearings are out of the way of
the food so smell isn't a problem. My suggestion of Moly Grease was based on
the fact that the heat will melt it and allow it to soak into the bearings -
although - if not - it will provide a lasting lubrication and take up some
of the slack caused by wear. I accept it is not an approach for a new
sintered bearing.
