How to Troubleshoot an Oster Water Cooler

Oster water coolers are installed on a house's primary water line.

Oster water coolers use a main-line filter to treat all water, purifying both hot and cold water for the home by removing sediment, minerals, dirt and rust before dispensing the water. The water flows from the main water line through the Oster cooler and back into the main water line. Oster water coolers can be installed by a professional technician or a homeowner familiar with turning off the main water supply and cutting the primary water line to install the valves and piping needed for the Oster water cooler. Once installed, troubleshooting an Oster water cooler is relatively simple to do.

Things You'll Need

• Tools
• Water supply

Instructions

1. Check the voltage on the power supply if the compressor does not run. Voltage should be within 10 percent of the voltage rated on the serial nameplate. Ensure the cold thermostat is turned "ON" and there are no loose wires.

2. Look at the internal refrigeration lines inside the water cooler unit if the water cooler is excessively noisy. The lines may be vibrating, as may the compressor mounting. Tighten if needed.

3. If no water disperses during very cold temperatures, ensure the water line is not frozen. Located in the reservoir, check to see if the baffle is in position. Repair if necessary.

4. Drain the water reservoir if water is leaking from the unit. The water reservoir may have become overfilled. Check the filter and the faucet gasket to see if they are excessively dirty or loose. Replace if needed.
