Hi Kennyc,

Know how you feel, it's rough when something dies on the bench or a week or two later - Handing back cash isn't fun at any time, especially as earning it takes quite a while in some cases.

As to fans generally, they're usually sleeve bearings for cheapness, and a squirt mostly does the biz for a couple of years at least, not had one back yet - Chris.

Hi Kenny,

I concur with Chris. Lubricant usually keeps them going for a few years, and I too have never had one back.
I certainly wouldn't pay that sort of dosh for a fan, and I'd say, nor would your punter.

As for shorting out the fan's feedback lead, I've done this with many Samsungs when replacing main boards on ones that don't use a fan, with main board that does. An error message appears - "Check Fan 2".
A link on the (absent) fan socket on the Main board sorts that out.

I'd personally take a punt on lubrication. Works for other applications as well.

Hi Bruce,

Talking lubrication and motors, have considerable problems with domestic dehydrators where sleeve bearings gum up rather quickly and motor comes to a halt - 'She who must be' gets a bit peeved.

Bit surprised as often the back bearing that sees no dust, is often the problem.

Realise, not a Sony, but wonder if it's in the nature of oil to gum, and if so maybe PTFE in some form might do the biz in all fans - Chris.

Hi give EMOS a ring or email him

Hi Chris,

You're probably correct about oil, especially heavier grades. Imagine they'd get a bit tacky, especially when you can't get the oil fired heater to work.

Not familiar with PTFE in the antipodes, but I use those cleaner/lubricant sprays like WD40....good old fish oil. Remember,  happy wife, happy life, or is it an urban myth.
