Why is my water dispenser not getting cold water?

When a residential water dispenser dispenses room-temperature water instead of ice-cold water, the malfunction is typically caused by a deactivated cooling switch, a dirty condenser grid, or a failed refrigeration thermostat. First, look at the rear panel of the dispenser and verify that the green cooling activation switch is firmly pushed to the "on" position. Second, ensure the unit is pulled away from the kitchen wall with adequate clearance for heat dissipation. Third, check for dust buildup on the cooling coils. You can troubleshoot cooling status easily by observing indicator lights. You can verify that your corrective action is successful when turning on the cooling switch or cleaning dust off the coils allows the internal compressor to run, delivering ice-cold water within one hour.
