1) Identifying the commercial refrigeration system issue is a must before beginning commercial refrigeration repair. One of the most difficult commercial refrigeration repairs that a technician will have to perform is an Ice Machine commercial refrigeration fix. Most commercial refrigerators and commercial freezers have a digital display, which indicates the temperature on the commercial refrigerator or freezer’s digital readout. In order to identify whether or not there is an issue with one of these commercial appliances, turn off the power supply from the commercial refrigerator or freezer for five minutes. During this time try turning on the digital read-out by pushing a button(s) on either front face, internal control board, wiring harness, switch assembly, or at rear appliance where connection strips are located).
2) Adjust commercial refrigeration system settings. Most commercial refrigerators and commercial freezers have a digital display, which indicates the temperature on the commercial refrigerator or freezer’s digital readout. In order to identify whether or not there is an issue with one of these commercial appliances, turn off the power supply from the commercial refrigerator or freezer for five minutes. During this time try turning on the digital read-out by pushing a button(s) on either front face, internal control board, wiring harness, switch assembly or at rear appliance where connection strips are located. If the unit does not reset after 5 minutes of being turned off then proceed to step 3 . If it does attempt to reset itself then the process could be resolved within unit itself. Some units have just a power reset button.
3) Checking a commercial refrigeration system for water leaks is one of the commercial appliance repairs that need to be checked regularly and just as important as commercial freezer commercial refrigerator commercial ice machine commercial freezers commercial refrigerator, commercial ice machine, commercial freezers commercial freezer commercial ice machine. Almost all units have a drain pan located at the bottom most part of unit that will have to be inspected by either removing lower front panel or back panel depending on model of unit, looking for signs of any water damage from any of the four corners of bottom most part of unit. If any signs are apparent check drain line for obstruction or clog by removing line, if none is found replace drain pan O-ring and put pan back into place ensuring a good seal between opening and new O-ring.
4) Testing commercial refrigeration equipment by printing pressure gauges is going to be one of the more complex commercial refrigerator repairs that a technician will have to perform since it requires multiple steps before beginning actual repair work. Pressure gauges need to print out green/blue clearly with no visible white spots present on gauge . If a white spot is present on pressure gauge it’s an indication that there might be debris in system which can be checked during step 5 below.
5) Commercial refrigeration system components need to be replaced if no visible debris is present in system, or gauges are printing poorly with white spots present on pressure gauges. There are certain commercial refrigerator repairs that require the technician to have previous experience in before attempting them. It is best practice to have a working relationship with factory authorized technicians who can assist when performing most complex of appliance repairs. Also these steps might vary based on manufacturer of unit so it’s imperative that proper safety measures are taken & units are properly serviced by qualified technicians.
6) Checking commercial refrigeration coil, fan housing, and fan blades for clogs or obstructions
7) Correcting commercial refrigerator compressor issues . Most compressor failures happen due to low refrigerant and/or dirty filter. There are two ways to ensure compressor is operational before finalizing price quote:
– Ask technicians if they have a hold down device that can be placed on the weight of the compressor in order to test for vibrations. If no such device is available, ask them if they will give you a reduced rate if the compressor fails during testing.
– Check if there’s a steady drip coming from the drain valve when the compressor is plugged in and unit has been off for at least 10 minutes or more depending on environmental conditions (example: high heat). Drip should be clear and not brown in color which would indicate oil leaking out (compressor failure). Also check for any signs of dampness around motor housing which would indicate possible moisture leakage.
Checking the connection strips, checking water leaks in your system if they don’t reset after 5 minutes, printing pressure gauges to make sure there’s no white spots present on them which would indicate possible debris or clogs in the system. Testing to see if any of these components need replacing by either removing lower front panel or back panel depending on the model of unit and looking for signs of any water damage from any four corners at bottom-most part of unit. Printing another gauge with a different tool other than just turning off the power button because it could be an easy fix within itself. If you have compressor issues that are not due to low refrigerant or dirty filter then ask the technician about their hold-down device that can be placed on the compressor or if they can give you reduced price repairs if unit fails during testing. If there’s a steady drip coming from the drain valve and it has been off for at least 10 minutes (more depending on environmental conditions) then it’s an indication that the refrigerator is not opening and closing properly and needs to be replaced. Lastly check all connections strips to make sure they are secure, as well as check the lower front panel or back panel of the refrigeration system for signs of any water damage from the bottom-most part of the unit.
