Delfield Refrigerator Troubleshooting


When it comes to cooling ingredients and beverages, many commercial kitchens turn to Delfield refrigerators to get the job done. From blast chillers to specification units, they’ve become a worldwide standard in the foodservice industry. Since these units run nonstop every day, there could be a few slip-ups over time. When your model isn’t running properly, it’s hard to find the root cause immediately. Fortunately, we have some Delfield refrigerator troubleshooting tips to help you identify the problem and get your unit back in working order.

Not Cooling Properly

There are a couple of factors that could be preventing your Delfield unit from cooling properly. First, check the condenser coil for a high buildup of dust or grease. This will block out cold air and cause the interior to be warmer than usual. Dusting and cleaning the coil should help solve this issue. However, if thick grease has damaged the coil, make sure to have it replaced.

A frozen or broken evaporator coil also keeps the unit from staying cool. A faulty coil can stem from blocking the air vents, cramming the interior with warm or humid items or leaving the door open. If the coil’s copper has excessive rust, this typically occurs when fruits, veggies and other acidic items are left uncovered in the unit. Too much rust will cause evaporator coil to fail quicker than usual.

Leaking Water

A frozen evaporator coil not only can cause the unit to feel warm, but it also can leak water inside the cabinet or under the fridge. While clearing space or cleaning the coil might help, you may need to have the part replaced. Another major reason for leaking is a blocked drain tube, which is usually located in the back of the unit. Check the tube for a clog, and clear it out with an air compressor or a shop vacuum.

Door Not Closing

A split or cracked gasket is one of the most common reasons why a commercial refrigerator door won’t close. Make sure to consult your owner’s manual to find the appropriate type for your model. Aside from the gasket, your unit could have damaged hinges that need to be replaced. If the hinges are in good shape, check to see if your fridge is level. You may need to readjust the casters and wheels to keep the unit level and the door sealed shut.

Common Delfield Error Codes

Select Delfield refrigerator models have error codes that display when something is wrong with your unit. Below are common error codes associated with different Delfield refrigerators. Please note that in some cases, a professional service company or technician will need to repair your unit.

  • E02 Code – An E02 code indicates that the fridge has a flawed coil sensor.
  • Lo Code – Like the Er 6 code on other models, “Lo” indicates that the unit’s temperature is lower than its set-point.
