Refrigeration Electrical Repair
Refrigeration Electrical Repair Grand Rapids MI
PLEASE NOTE: A licensed electrician should be retained and used to wire any circuits supplying power to a commercial freezer. Severe and permanent damage will result from improper wiring of your freezer!
What are the electrical requirements for our merchandisers?
It is imperative to check the voltage and amp draw to determine proper line and fuse or circuit breaker size. This information is obtainable via the Data Plate found inside the unit.
Check power supply for low voltage. If voltage reads “230” with no load, and it drops below “207” when the compressor tries to start, it’s an indication of too little supply wire or possibly too long of a run.
It is also imperative that a separate circuit is run for each cabinet to prevent another appliance from blowing a fuse or loss due to low voltage from an overloaded circuit.
What is the plug type needed for a freezer?
Most two and three-door self-contained freezers will have and come with a NEMA L14-20P twist lock plug. This is a 20 amp plug but interestingly reads 125/250 volt on it. The cabinet must be grounded.
Can this plug utilize a 3-wire system?
No. Most manufacturers have a 4-wire system. There should be a red wire and a black wire (power legs – hot), a white wire – which is neutral, and a green wire – which is the ground. The ground will have an “L” shape to it on the plug configuration. It is important to note; when wiring the plug, the “L” shape – ground leg is the green wire, the opposite leg will be the white – neutral leg. The other two legs will be the “hots” – black and red.
Can I wire the neutral to the ground?
Although it is possible and the unit should still work, we do not advise you to do this! By wiring the neutral and the ground together, it eliminates the use of the run capacitor and will cause and create “hard” starts for the compressor. This will reduce the life of the compressor.
PLEASE NOTE: It is imperative for the customer to know the requirements of the merchandiser they are purchasing. Please contact the manufacturer for an owner’s manual – most have these available online and all offer these for free. Also, hire a licensed electrician if you are running a new circuit or even to test the one you currently have.
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 🙂
