    Troubleshooting common repair issues for commercial refrigerators

    If you are searching for commercial refrigeration troubleshooting, this post should help!

    Commercial refrigerators like True T-49, and other commercial appliances, can have issues and may need some maintenance. Even durable brand like True will need to be repaired, so when you have maintenance issues, you need to know how you can fix them efficiently and quickly, with help from a commercial refrigeration service. You can also solve the issue yourself it is simple. Below are common problems that you could have, and a few tips on how you can find out what is wrong.

    Power Issues

    If your refrigerator isn’t powering up, you could have an issue. Make sure that the power switch has been switched off. Ensure that the power cord is plugged in properly and all the way, as it could have been knocked out of place. If that isn’t the case, then check if the ground wiring and wiring to the outlet is active. The issue could be the power supply, and not the unit itself. Use a voltage detector to ensure that it is active.

    Remember: Many manufacturers will tell you to never use extension cords for a commercial fridge, because using them voids the warranty.

    Temperature issues with the refrigerator

    Are you having issues with the temperature in the fridge? Is it not getting cold enough? Having the fridge keep the food cold enough is a needed process for commercial appliances, and you will need to address this quickly.

    First, take a look at the fridge. Is it up against the wall? The fridge will need to be away from the wall slightly to allow it to circulate air correctly. Commercial fridges are made to withstand a lot of open and closings, but there are times when the gasket can get worn down from normal wear and tear. The door need to close properly and completely seal, so that the unit can cool properly.

    You may also have an issue with the temperature gauge giving an incorrect reading or is broken. If this happens, manufactures have made the gauge simple to replace. The incorrect temperature reading can be because of a blocked vent. Check the temperature by using a thermometer to ensure that your thermostat is working.

    The compressor that is used to keep the food cool, if it isn’t working, it won’t cool right. True and other companies have outlined in the manual how often you should clean the compressor, but it is every 90 days. Grease, hair, dirt, and more could build up within the compressor can keep it from working. Make sure that the compressor has been recently cleaned, and that it is running like it should.

    Is it starting to run hot? Is it freezing up and is collecting ice? Then you need to check if the evaporator fan is working right. You will need to melt the ice off the evaporator, if there is ice by turning it off.  The coils on the evaporator need to be clean and you can locate cleaning tips in the manual. Ensure the drain lines are clear as well.  You may notice that only part of the coil is freezing, which means you could have a low charge, so the sub cooling and pressure may need to be checked.

    Lighting Issues

    Sometimes you could have a small issue like the lights not working in the fridge. If that is the case, then look at the lights. Some brands will use LED lights, so if you need to replace the bulb, ensure that it has been approved and verified by the manufacturer, or you could burn the socket out. Read the manual to ensure that you are doing the right repair option.

    When everything else has failed

    If you have troubleshooted the fridge, and you can’t find the problem, then contact a commercial refrigeration repair service. There are some brands that will make it easy to locate a servicer by listing services on their site. Remember, if your fridge is still under warranty, check the details of your warranty to ensure that any repairs made by a third party or yourself doesn’t void out the warranty.

    You may need to look into maintenance plans that are offered by a repair service to ensure that your fridge runs easily and doesn’t have an issue when you may be inconvenienced. Regular maintenance helps to lower issues for larger repairs in the future.
