PROBLEM

Totally Inoperative

No cooling

No water dispensed, concentrate only

PROBABLE CAUSE

•No power to dispenser due to tripped circuit breaker

•Loose or broken power supply connection inside dispenser.

•Line voltage is not within +/- 10% of nameplate specifications causing compressor overload to trip

•No water in water ice bath or water level extremely low exposing the ice bank sensing probe

•Defective Ice Bank Control or sensing probe

•Cabinet fan is inoperative result- ing in warm concentrate (water continues to cool)

•Compressor short cycles on overload

•Compressor starts but hums and trips overload
