I’ve worked on a lot of different brands of refrigerators over the last 15 years and none have left a mark quite like the Samsung brand. I’ve been factory authorized for almost 15 year now I’ve seen a lot of appliances come and go. The amount of trouble folks seem to have with these particular refrigerators is quite impressive to me.
I want to work on just one of the common issues these refrigerators seem to have. A knock, a tap, or a grinding type noise.
These side by side and bottom mount Samsung Refrigerators have several common issues that can causes these noises. I’ll try my best below to describe them all. I’m hoping with the provided information you will be able to not only learn something but you will be able to apply that new information into a feeling of accomplishment by fixing your broken appliance. If you require more help, please use the “Ask Matt” page @ the top of this page. I can provide step by step detailed directions on how to make this repair yourself.
How To Fix A Noisy Samsung Refrigerator:
First things first..pinpoint where the noise is actually coming from. One thing to keep in mind is that the fans inside will only run when the doors are closed.
Usually when the sound is coming from the inside it indicates an issue with the defrost heater or defrost drain. Occasionally the door being left open for to long can and does cause this issue. The warm air hits the cold air and creates condensation. This then freezes on the evaporator and the evaporator fan blade hits the frost/ice and creates a loud noise.
Now the door being left open, a faulty defrost component, or a plugged defrost drain line can cause this. This is where the problem can get tricky especially if the unit has been left in a noisy or not functioning at 100% state for a week or longer. The frost/ice compounds and makes it difficult to determine what exactly is going on. This is where you will need not only special tools but also the ability to read schematics and multimeters. A basic understanding of electricity is must when servicing an appliance.
The defrost heater gives off heat during the defrost cycle to melt the frost on the evaporator. If the heater fails, the frost will build up so thick the fan ends up hitting the frost. Eventually the frost/ice will stop the fan blade and the temperatures inside will raise. This is normally when folks set up a service call. By now it’s compounded for a week or better and is a solid block of ice behind the panel. Sometimes when the defrost drain line is clogged this will also happen. You have to defrost and test the heater to be certain of what exactly is going on. The defrost water not draining will build up from the bottom up. When this happens the situation is even worse because it truly is a block of solid ice you have to melt. Once the ice is melted you can then try and clear the drain line with a turkey baster and hot water or something similar.
The drain line on Samsung refrigerators is not an easy one to get to or clear. If you require more technical help after reading this post, please use the “Ask Matt” tab at the top of this page. I’m always happy to help.
