How to troubleshoot freezers, troubleshooting commercial freezers, troubleshoot. All Commercial Freezers have similar and basic components that are common. For example, all freezers will have a compressor, condenser, and evaporator. AND all commercial freezers will also have similar and basic reoccurring problems. Most of these problems are user or consumer related. I will address some of these issues here A. LACK OF MAINTENANCE I have already address this in other places on this site so will not need to redo so here. I do mention it though as it is the most common and reoccurring problem.

ICED COIL When the evaporator coil ices, the ONLY means to correct the situation is to shut the unit down and totally and completely defrost the unit. Often times, consumers try to cheat this process by only shutting the unit down for an hour or two thinking the unit is completely defrosted. Unfortunately, an hour or two rarely is long enough to defrost the coil completely. WARNING I do not recommend a consumer defrosting a unit without proper training or the assistance of a refrigeration technician. There are several causes for an ice coiled which I will discuss in great detail at ICED COIL C. POWER ISSUES there are certain wiring issues that can develop a problem after a period of time and will not show themselves immediately. One of these problems is wiring 2. I have addressed this issue at ELECTRICAL WIRINGD. BAD START COMPONENTS This one is tricky as most refrigeration techs confuse this one with a bad compressor. It is imperative to know hoe to test if a compressor is good or bad. There are different ways to diagnose this and to test some use an electrical test to see the amp draw. Descargar Ingles Sin Barreras Full Mega'>Descargar Ingles Sin Barreras Full Mega. This is a good way to check the compressor. However, a better way is to use an Annie or hermetic compressor analyzer. Unfortunately most techs do not carry one of these nor have they ever heard of them. That said, when a compressor is weak or gets too hot, often times in takes out the start capacitor or the relay. There are numerous ways to verify or check these and they must be done before automatically declaring the compressor is bad. For more details on starting components, see STARTING COMPONENTS for further info and details. SPECFIC COMMON PROBLEMS WITH TRUE MASTER BILT BEVERAGE AIRAs goofy as this may sound, I always recommend starting with the most basic search while trouble shooting freezer cooler problems. Lets start by checking for adequate Power to the unit. Now I know that sounds mundane, BUT hear me. We need to check the onoff switch, the reset button if equipped, and the breaker panel. Most self contained freezers require 2. Many of customers have told me that 2. A simple volt tester can verify the correct power. Also check the cord for cracks, fraying, damage. I can recall several service calls where the only problem was where the cord got damaged when the unit was moved most likely got caught under the unit. ALSO One super common often overlooked problem resides in lack of communication Here again, some commercial freezers WILL NOT have the interior evaporator fans or lights come on until the box has reached a pre set from the factory temperature.

Simply turn off all power breakers and check the wiring. Predictably, each manufacturer has some common problems and areas of trouble. COMMON TYPICAL PROBLEMS WITH TRUE FREEZERSThermostat We have discovered one of the most common problems with the True freezer is the factory installed thermostat. Hence, the upgrade the manufacturer has since made to replace the factory original. There are easy and practical ways to test the thermostat. See. Trouble Shooting Thermostat for details and information on how to verify if this is the problem. Capacitors For several different reasons, the start capacitor, run capacitor, andor relay may fail. Often times this is misdiagnosed as a compressor failure. In particular, when the starter capacitor fails, the unit often will make a humming noise or a clicking noise. In fact, often times this can be a very inexpensive and easy fix. See Diagnosing Starting Components for further info and details. Lights The True has male female plugs near the compressor for the door lights. If one of these plugs comes undone none of the lights will work. This is often overlooked but is extremely common as there is very little room for the plugs and in fact, simply pulling the condensing unit out will often times require disengaging this plug. Nitro Capacitor Installation CostIf it is overlooked when pushing the condensing unit in, the lights WILL NOT work. The True, for example, also is prone to burned out electrical sockets for the lights. This is NOT due to design flaws. ALWAYS due to improper bulb installation. The fact is the replacement bulbs are incredibly expensive. The problem is, the discounted bulbs are a 1. As is the case with most things in life, you can pay much less for the cheaper bulbs up front AND pay a whole lot more once the sockets fry and need to be replaced. ALWAYS USE THE CORRECT FACTORY RECOMMENDED BULBBallast Sometimes the ballast will need to be replaced. Providing everything else has been thoroughly checked over diagnosed, then check the ballast. This is fairly simple to replace and often times can be purchased from the discount box stores. I strongly suggest one make certain to get the same size ballast as the old one. Here again, wrong or incorrectly sized replacement parts can and will cause other costly damage down the road. COMMON TYPICAL PROBLEMS WITH MASTER BILT FREEZERSProgramming From experience, the Master Bilt freezer has very little common known, obvious problem areas hence the reason it ranks so high on my favorites list. However, we occasionally get units in that dont work or are not properly working. Usually we find a small leak due to vibration in the suction or liquid lines. However, nine out of ten simply needed to be re programmed. Interestingly, I often wonder or ask myself how it got out of programming to begin with as this is a pre set function from the factory. Fortunately, re programing the Master Bilt Freezer is a fairly simple process. And I do have them. Master Bilt Freezer and do not have the codes, please feel free to use the ones I have posted here. Check out Master Bilt Programming Codes As stated above The Master Bilt seems to occasionally develop leaks. This is not necessarily a factor or design problem but one more of set up, positioning, andor delivery. I personally like the plumbing of the Master Bilt but it is subject to the tech working on the unit. Extreme caution should be used while pulling the condensing unit out and pushing it back in. A simple little vibration unseen can become an expensive repair service call. UPDATE June 2. 01. The newer MASTER BILT freezers are out. These units run much more efficiently and are less likely to have compressor failures.
