Patton cooling fan

My Patton fan became squeaky and slow to start so I opened it up, cleaned and oiled the bearings and shaft with sewing machine oil and when reassembled it ran great for one day then stopped entirely. Where did I go wrong?

Patton fans are usually pretty reliable. A drop or two of oil on the bearings should be all that's needed.
Maybe the motor isn't fully back together ?

But it ran great for a whole day after reassembly. Very quiet, no problem stopping and restarting, then...nothing.

Then something happened in the rebuild, the motor overheated and now the fan is dead.
The thermal protector they put in most fan motors tripped and is not resetable.

To add to the mystery I turned on the fan today and it runs like a greyhound. It's a puzzle.

Maybe the on/off switch is intermittent. With the fan running pull and insert (after the fan stops) the plug a few times. If the fan restarts each time, I would consider changing on/off switch.
