Today I replaced one of the condenser fan motors on the staging building chiller. As I was removing the motor and support/guard, the last of the spot welds broke. Had this happened during operation the fan would likely have fallen into the chiller causing a considerable amount of damage.

I took the support to the weld shop, cleaned and re-welded it.

While I had the unit disassembled, I also cleaned the coils which I would estimate were 40% blocked with debris.
