Hamilton beach water cooler is not cooling

Sounds like the thermostat is your problem. That would be the only thing that will allow the unit to continually run.

When empty of water remove the back panel and the cooling fins are most likely covered with an inch of dirt! Find an air compressor and blow out the dirt. It worked on mine!

Check to see if fans are working i just bought a used one and one of the fans was not working and i fixed it and sems to be working

Check the fans

the thermistat is shot replaced it

Change cold control

Replace Thermostat and find the model number, Sea Breeze

Glen,
We purchaced this water dispencer about 2 years ago, everything was working normal, water heater works fine and the cooler would come on and go off normally,until you dispenced cold water and then the coller would cool down and shut of like it's supposed to.
Afetr a couple of years , one day it started cooling continuously and wouldn't stop, I've just shut the cooler switch off on the back of the unit until i can figure the problem out,unit #(87330).
I believe the problem is in the circuit control board, but with out further testing i can't be sure .

Sounds like the fans have stoped turning for the cooling system. If you cannot hear the fans turn on when you flip the COOL switch this is your problem. Pick the fans up at a computer parts store like Frys. Any other part failure on this unit other than a loose wire is not worth repairing.

thermostat is stuck. try buying a water cooler control from a local supply house.
