Not much detail in the image. It's too small.

It was in a surface mount box. Now, what happened? Your picture orientation should help

The unit was installed upside down in the can resulting in the hi limit being below the heating element instead of above. The fan had quit or slowed up so that didn't help. Bearings were dry. Of the several units similar, this is the only one with a high limit in that position. The rest are on the heater element fins.
