Good day, Having done a lot of work on commercial equipment, I have found that many of these units need an added "interruption timer" to keep the coils clean. They are available from any commercial refrigeration parts house. There are many makes models and styles, and are available in 115 and 208/240 volt styles. It involves cutting the wires to the compressor at a convenient location, and wiring in the timer. The timers are adjustable, and usually for an initial setting, are set to force the compressor to shut down for 3 times a day for approx. 30 minutes. This forced off time, prevents frost from ever building up to any degree, since the fans inside the unit continue to run, melting the frost off at regular intervals. Adjust timing as needed.
Hi, Usually when this happens it is because of a problem with the fan that moves cold air from the freezer section of your unit to the refrigerator section. Either the fan has gone bad or the unit has frosted up to the point of stopping the fan. Try defrosting (unplugging) the unit over night and then check it to see if the fan runs. If not then replace the fan. If it runs and then stops after awhile like days or even a few weeks, then you may need a defrost timer. The other thing that can cause this is the heating element going bad, but this is not usually the problem. The element can be checked with an OHM meter. If the coil does not have any resistance then it is bad.
You can find parts for your unit by doing a search for “appliance parts”. Once you get the results of the search, pick a site and when it comes up it will usually ask for the model number of your unit. Enter your model number and you will then get a page with exploded views and a parts menu. Find the part you need and then order it. Check a few different sites to be sure that you are getting the best pricing. Most sites can have the part to you in a couple of days.
I hope that this will help you to solve your problem!
