5 LG Commercial Appliance Questions I Learned the Hard Way (So You Don't Have To)

I've been handling LG commercial appliance orders for 8 years. Heres what nobody tells you.

In my first year (2017), I made a classic mistake. I assumed 'commercial grade' meant 'indestructible.' Didn't verify. Turned out that perception nearly cost us a major hotel account. After three rejections in Q1 2024, I created our pre-check list. We have caught 47 potential errors using it in the past 18 months alone. This FAQ is rooted in those mistakes—the ones that cost real money and real credibility.

Let's get into the questions I wish I had asked.

1. Why is my LG refrigerator running but not cooling?

This is the single most common call we get. I assumed 'running' meant 'working.' Didn't verify. The compressor runs, but the cooling system fails. Turned out the evaporator fan motor was frozen over. On a $3,200 order, every single unit had the issue. $890 in redo costs plus a 1-week delay.

Here's what I've learned: If the fridge is running but not cooling, the first check isn't the back panel. It's the condenser coils. Dirty coils cause the compressor to overwork and the system to shut down prematurely. LG recommends cleaning them every 6 months. I'll be honest—I check them every 3 in my commercial kitchens. Better safe than sorry.

If the coils are clean and it's still warm? Check the evaporator fan. A bad fan won't circulate cold air. I've seen this on dozens of units, from the standard to the LG mini fridge models.

2. Can I use an LG mini fridge for a commercial break room?

The short answer: depends on volume. A mini fridge is perfect for a small office or a break room with 10-15 people. But if you are stocking for a large team or storing temperature-sensitive medications, it won't cut it.

I recommend the LG mini fridge for most small break rooms. But if you are dealing with a busy commercial kitchen or a clinic, you might want to consider the larger commercial-grade models. The mini fridges have a lower BTU rating. They recover temperature slower. I learned this after a week of complaints from a dental office. The mini fridge couldn't keep up with multiple staff openings and closings. Cost me $450 in wasted product and embarrassment.

Here is how to know if you are in the 20% where it does not work: if you open the fridge more than 50 times a day, get a full-size model. Simple.

3. What is the most common sizing mistake with commercial LG products?

This is the number one error I see. Sizing a refrigerator or condensing unit incorrectly. I once ordered 12 LG units for a new restaurant. Checked the specs myself. Approved it. Processed it. We caught the error when the installers called: the door couldn't open fully because the aisle was too narrow. $3,200 wasted. Credibility damaged. Lesson learned.

I assumed the specs were 'standard.' They were not. You need a minimum of 2 inches of clearance on each side for ventilation. For the taller models, you need 6-8 inches above the unit
