My question concerns our gas fire place. it is the kind that is vented
through the side of the house.

We used it all last winter. This fall when we started it up the fan ran
for a while made some noises, and the squirrel cage fan stopped. At
that time I cleaned the area under the firebox, there were were some
lava stones.

I put it back together and it ran for a while then stopped. Messed with
it and tried again and it ran for a few minutes and slowed down and the
fan started to hum

I took it out and put a little oil on the shaft and worked it down into
the bearings. It has been running for about an hour and a half.

Is it normal for a small motor like is on the fan to run hot? This one
is running about 200F. (taken with thermoprobe on a volt/ohm meeter
with the probe on the out side of bearing housing over the bearing.)

Thanks

I have no experience, but I can tell you that it is too hot.
Does it have a start capacitor, or run capacitor, or is it a small motor?

Sounds like maybe the winding might be shorting if the bearings are free
now. If it is not free spinning, than that is still the cause of the heat.

Figure the motor should be no hotter than 120 at the most.
