If the commercial refrigerator does not seem to be running, check to see if it is turned on. If there is a switch, check to see if it is in the on position.
Check the plug and power outlet. If there is no power, it may not be the unit but the electricity. Sometimes faulty wiring can cause short circuits. Check the plug and the wiring to see if anything is broken or loose. You can use a non-contact voltage detector to test the presence of voltage in outlets. It is a quick way to find broken wires or loose connections.
If the commercial refrigerator is on, but not cooling, check the internal temperature with a thermometer to confirm the functioning of the thermostat. An incorrect temperature read could mean blocked vents or a broken thermostat.
Another reason the unit might not be cooling is worn gaskets. Regularly opening and closing refrigerator doors creates a lot of wear and tear on a unit’s gaskets. Check to see if the door is closing properly and sealing well.
If it’s not the thermostat or gaskets, the problem might be the compressor. The compressor is the motor that distributes the coolant through the condenser and evaporator coils. You can usually diagnose a compressor problem if there is a loud noise coming from the unit. Compressors are sealed and are not easy to open up, fix and reseal. This means the compressor will have to be replaced.
If it’s not the compressor, it may be the condenser. The condenser coil removes free heat from the refrigerant so it can be used for cooling. Check to see if the condenser coils are clean. Sometimes coils get clogged or cracked, which can cause a refrigerant block or leak.
Next, check the evaporator coil. The evaporator coil pulls heat out of the inside of the unit. Sometimes the liquid inside the evaporator coil will freeze. The coil should be clean and the drain line should be clear.
You should also check the condenser or evaporator motor fans to see if they are rotating correctly. The condenser fan is located outside the unit and moves the refrigerant through the coil once it has been compressed. The evaporator motor fan is located inside the refrigerator on the ceiling or on the top of the unit.
Commercial refrigerator units are complex pieces of equipment. If you do not have experience handling maintenance issues on these systems, you should contact a refrigerator repair technician for assistance. A trained professional can help you fix the unit faster.

Gary R Jeff designed a great Mitsubishi Mini Split for my new Music Room. Julio and Marlon did a great job on the initial pre-plumb, and Julio and Jake returned to finish the install. I did have one minor glitch, and Jeff sent Barry out to take care of that. Great equipme...
Lisa G Have had nothing but positive experience working with R&S. Brittany is the front end of the company and does a great job representing company. friendly, pleasant and helpful. Provides accurate information and follows up as she says.
Sean H. I had R and S come out to my house for the second time in the last couple of years to fix an issue with our heating system, and they were able to show up quickly and promptly and fix the issue the same day. The folks I have dealt with at R and S have all been very friendly and helpful in explaining the two issues with our heater thus far. We've had very good experiences and would definitely recommend to other homeowners.
Mancy M. I would recommend R & S Mechanical at any time for those who are looking for professionalism and ability to make a major job look like it's a minor one. I contacted R & S as one of 5 suppliers and service companies to install a new unit in my house. Even though price was a factor, but I was also looking to work with an organization that would be honest and caring. I did find such values with R & S. They were the only one out of the five who actually called to follow up on their offer and ensure that everything was well explained and clear. Absolutely great guys and they made sure to keep the place clean after they left. I definitely made the right choice.
Jennifer R. I have dealt with R&S since I moved to Raleigh four years ago and they have taken consistently good care of my HVAC units. They are prompt, professional, courteous and definitely pick up after themselves. They even call me to schedule regular maintenance that comes with my service contract instead of me having to remember. I can get an appointment very quickly if something breaks on me and they always arrive early. I'm overall very satisfied.
Gail S. I have always been pleased with their service. They are quick to respond, even on weekends. I would definitely recommend them.
Carol C. Our overall experience with R&S has been exceptional. We have been homeowners for over 30 years and have never had better service, concern and respect as we have received from R&S. Highly recommend.
Barb and Jerry Our AC system failed on a Friday afternoon at our Daughter's condo. Shortly after our call, Randy and Mike came to our condo, diagnosed the unit and loaned us portable cooling units over the weekend. They installed a new system and got us up and running the following Tuesday. Their prices and service were great! Very responsive, very straight forward, no hard sell unlike the big companies. Highly recommended - excellent service!
