All commercial freezers have similar and basic components. For example, all freezers will have a compressor, condenser, and evaporator. Similarly, all commercial freezers will have common and basic reoccurring problems. Most of these problems are user or consumer related. View our commercial refrigeration troubleshooting guide for help on a variety of common issues.
Consumer related problems include:
Common problems with True, Master Bilt, and Beverage Air:
We recommend starting with the most basic search while troubleshooting freezer/cooler problems.
Start with checking the power to the unit (on/off switch, reset button, etc.) Then, check the cord for cracks, fraying, or any other damage.
Check for power or wiring issues. If after a lengthy period the lights do not come on, we typically find the ground wire or the neutral has a poor connection.
Common problems with True freezers:
1.) Thermostat: We’ve discovered one of the most common problems with the True freezer is the factory-installed thermostat. 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.
2.) Capacitors: For several reasons, the start capacitor, run capacitor, and/or relay may fail. Often 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. Fortunately, this can be a very inexpensive and easy fix. See Diagnosing Starting Components for further info and details.
3.) 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. If we overlook it when pushing the condensing unit in, the lights will not work.
The True is also prone to burned-out electrical sockets. This is not because of design flaws but is always due to improper bulb installation. Replacement bulbs are expensive and there are bulbs from discount home improvement stores that will “fit” the sockets. The problem is, the discounted bulbs are a 12w bulb and are too powerful for the sockets which are wired for a 10w bulb.
ALWAYS USE THE FACTORY RECOMMENDED BULB!
4.) Ballast: Sometimes the ballast will need to be replaced. Providing everything else has been thoroughly checked over/diagnosed. You would then check the ballast. This is fairly simple to replace and oftentimes can be purchased from the discount box stores. We strongly suggest you buy 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 problems with Master Bilt freezers:
1.) Programming: The Master Bilt freezers have little commonly known issues. However, we occasionally get units that “don’t work” or are not working properly. Usually we find a small leak because of vibration in the suction or liquid lines. However, nine out of ten simply need to be re-programmed.
The Master Bilt seems to occasionally develop leaks. This is not necessarily a factory or design problem, but one more related to set-up, positioning, and/or delivery. Use extreme caution should while pulling the condensing unit out and pushing it back in. A simple little vibration can become an expensive repair/service call.
The newer Master Bilt freezers have the hermetic compressors, which are a significant improvement over the semi-hermetic compressors. These units run much more efficiently and are less likely to have compressor failures.
The newer units have been revealing unique problems than units of the past. One common problem has been a bad defrost heater for the condensate drain. Contact us for more information on how we fix problems related to the defrost heater!
Common problems with Beverage Air freezers:
1.) Compressor: The biggest drawback of the Beverage Air freezer is its 1hp compressor. Issues related to the compressor are typically user related. Improper maintenance can be attributed to premature compressor failure. The valve plate can be easily replaced/repaired providing the failure is caught expeditiously. Please note, even with a valve plate failure, the compressor will continue to run and often will continue to maintain temperature. However, it will do so under a tremendous load on the compressor and, if not caught soon, will ultimately damage other critical components. These more terminal problems can be expensive and will generally require a new compressor.
2.) Freezers: You either need to have a TXV (expansion valve) or a capillary tube. The TXV valve has adjustments on it that control the amount of gas flowing through and into the expansion coil. The backside of this valve has a screen inside the flare nut. This screen is basically an oil filter. We have found countless machines that had nothing majorly wrong with them other than this screen being plugged. The screen gets plugged with dirty oil or other contaminants, thus restricting the flow of gas.

Rick and Tammy, we are so glad to hear that you like our pork! You are more than welcome to give us an order and we will have it ready whenever you can make it down. It was great meeting you both and the freezer runs great! We just love it and I know the customers like being able to pick out what they want, helps with compulsive buying too! LOL. It looks so nice full of pork! Blessings to you both as well and we hope you have a wonderful and safe Thanksgiving. 🙂
I have been doing business with this company for over 3 years. They service all of my coolers every 6 months or so to make sure they are working properly. I have bought 3 coolers over the years some new and some used. The level of service and promptness to service calls is top notch. Great family owned company to work with!
Thank you for getting me the cooler. We had some really cold icy weather last week so fedx was unable to deliver Monday. I have it now in place and it looks good. Thank you for doing such a great job wrapping and palleting the cooler. I will try to send a picture with it filled with product. Thanks again
Fast response time! Knowledgeable staff! Very professional and easy to work with! Cost effective! Weidenfeller Refrigeration has been my sole provider of service for the 4 industrial coolers and 1 industrial freezer on my blueberry farm for the last year. Always available at a moments notice and consistently shows up in my time of needs. Emergency after hours service was also available to me! They will take the time to explain the problem in a way anyone can understand, offer different solutions, and leave it to the customer on exactly how to handle it. Rick has even saved me money several times by maintaining several wear and tear parts rather than just replacing them. 5/5 would recommend to friends, family and other industry professionals.
I just received a new Migali Mega Top prep table / cooler from The Freezer Depot. I saved over 20% off of the traditional brand names and like this unit better than the (2) named brand units I currently have in my kitchen. This new unit is awesome!
Rick has been a great resource for me in figuring out the changing refrigeration needs of my small business. He always has a good selection of units, great service, and straight, honest answers. And he delivers!
The Freezer Depot provided me a top of the line Master Bilt freezer in great condition at an amazing price. I saved thousands of dollars! Best of all, I was given excellent service and support. I’ll never buy a new freezer again!
Buying through the internet is often a tentative experience at best but with Rick and The Freezer Depot it was pure pleasure. Initially, I was shopping for a two door freezer and two door cooler but then decided on getting three door units. Rick was informative with the answers to my questions and made recommendations when asked. He made my purchase extremely comfortable and easy. The units I purchased needed to travel to Fairbanks, Alaska and Rick did an excellent job packing them to ensure their safe arrival. They are an excellent addition to our store and are helping to increase sales. You will be my first choice with future needs. Thank You, Rick.
We purchased a used freezer from The Freezer Depot and was very happy with it. We did run into a few problems with it which Rick came out and addressed in a timely manner. After a couple of times Rick chose to replace it with a upgrade he had at his facility at no cost to us. We really appreciated the service and commitment from Rick to stand behind his product and resolve any open issues, thanks again.
Just wanted to say thanks for coming out to Ann Arbor to take care of the problem with our freezer. I took your invoice to the other company who had misdiagnosed it, and they gave a full refund of the charge for that day. (I’m still out their other fees for the Kelvinator that we traded in to you, but oh well.) In the future we will call a refrigeration tech in our area as you suggested, not heating/cooling. Thanks for the help and if you need any testimonials for your website we can provide one 🙂
