I had something similar. The water cooling system at the local Coke
bottlers plant was short cycling. I quickly tracked the problem to
low AC voltage, then battled the city to get them to crank up the
transformer tap which fixed it.

The motor starter was mounted above a table where several women
worked, and the starter cycled in and out so fast it was like a super
buzzer with lots of arcing. The plant manager said some women had
hysterics each time it happened.

Still better than the time the float switch on the syrup tank failed
and they ran syrup through the whole, carpeted, office complex! Glad
I missed that.
