The Quick Guide to Commercial Refrigeration Problems

Commercial refrigeration is key to the success of any restaurant and keeping your units properly running can save you both time and money. Whether your commercial refrigerator won’t stop running when you want it to or simply won’t run at all, this quick guide will help you to troubleshoot all of your refrigeration problems and find the right solution.

If your commercial refrigerator won’t run at all or won’t stop running, you’re probably looking at a defective thermostat.  You can test this easily. First, unplug the unit and open the evaporator housing. Locate the wires attached to the thermostat, remove and connect together with electrical tape. If the unit runs properly when turned back on, simply replace the thermostat.

Encountering difficulty with rising temperatures? The first step towards a solution is identifying what type of refrigeration thermostat your refrigeration unit uses.  If you’re dealing with either an air-sensing thermostat or evaporator-sensing thermostat, you can replace the part yourself. But be aware that the two are not interchangeable, so be sure to correctly identify which you’re working with first. If your commercial refrigerator uses a low pressure control, you’re going to have to call a service technician to get the part repaired.

Problems with a broken or malfunctioning fan motor need to be dealt with immediately, because without proper refrigeration your food is at risk of going bad quickly.  First off, you need to identify whether your unit uses a condenser fan motor or evaporator fan motor. A condenser fan motor will be found outside the refrigeration interior while an evaporator fan motor is found within the interior. Replace the motor fan by identifying the specific model of motor and blade (both are usually stamped into the back of the product and are easily accessible) and ordering a new one. Installation is usually brand-specific and can be found in your unit’s accompanying guidebook.

If the door to your commercial refrigeration unit is improperly closing, you could potentially be throwing away energy and money. The quick fix to this problem is simple: you need to update your gaskets. This do-it-yourself fix merely requires you to ascertain the dimension, brand and style of the existing gasket and order a new one. Replacing old gaskets is as easy as popping them off and snapping the new ones on.

The Quick Guide to Commercial Refrigeration ProblemsIf you need to replace faulty hinges or latches in your commercial refrigerator, start with simple identification. With both hinges and latches, you must determine whether you’re working with flush or offset parts, which is determined simply by running your hand over the part, looking to see if it is smooth, or flush, or not. If you’re working with offset hinges and the offset size is not available on the back of the part, you’ll need to measure the distance from the wall surface to the door surface to find the correct size. In terms of latches, there are two different types: magnetic  and those with a strike-and-latch lock. These latches will have an easy to identify number on them. With both latches and hinges, the easiest method is always to look for their ID number to order the right part the first time around.
