Turned my oven on tonight and the fan just hummed and didnt spin. Turned
it off and spun it with a stick poked through the slots and it ran fine
after that.

Im guessing its on its way out but was wondering if there is any future
in trying to lubricate the bearings or whether to cut my losses any just
order a new fan before it fails totally.

If it *is* worth trying to lubricate the bearings, what sort of oil should
I use?

The one I came across is where the fan motor was a modest distance from
the fan, where the shaft went through the rear of the oven and so was
much cooler than the oven temperature.

In which case anything to hand should be good. You might find that it's
crud that is seizing the motor and a liberal spray with oil will assist
greatly if only to displace the crud.
