If it is that abused,
you should check all fans and filters on the machine,
even the ones to the electricals.
As a precaution, take a copy of your machine parameters now, as a backup

We recently purchased an abused '91 LB15 w/OSP5020L control. After the initial power up, we discovered the bearings in the spindle motor were bad. We sent the motor to be rebuilt. Yesterday while I was trying to get RS232 communications working, I noticed the cooling fan on the motor slowing down and eventually stopping. So I guess $650 doesn't cover bearings in the cooling fan. This morning it didn't even start and I could smell hot electric. I don't have any schematics for this machine, but I would figure there is a breaker or fuse for the cooling fan somewhere. Any ideas where specifically I should look? I know it should be in the back someplace.
Thanks,
Jon

Thanks, those are good ideas.

Be careful here. If you run this machine with no spindle motor fan you will KILL your VAC spindle drive unit. If it is a TYPE A unit and you kill it. It is NO LONGER EXCHANGABLE! Thus you just cost your company 10K to replace it with a TYPE B unit.
Don't worry, was not running the spindle, just trying to get the RS232 working. The bearings have since been replaced in the fan and it's working fine.
Thanks,

Okay good. I responded to that post as well.
