Frigidaire refrigerator makes chugging sound

SOURCE: Noises when starting up

Mine also makes a knocking noise...like someone's at the door (it freaks the dog out every time). The customer support people say it's normal and so far it hasn't died after two years, so I guess it's not a problem.

SOURCE: Samsung side by side refrigerator not working

I am somewhat of a fix-it guy and here is my take....I also have the same refridge with other problems, and have done alot of research and discussions with the local repair techs and Factory rep. Here we go: The Samsung models are very prone to problems arising from power fluctuation's that fry the motherboards. One problem may be that the defrost circuit fails and the unit freezes up causing a lack of cooling and loud banging of the compressor. To run a diagnostic of the unit, you need to press both power freeze buttons for 10 seconds beeps will sound and release, the dashes on the display showing if any circuits are bad.(self diagnostic) This is what the service guy will do then come in with the part and replace. With a bad board, the diagnostics reveals no problem and the service agent will just start replacing parts, at your expense! Also the part #'s will show discontinued but they just changed parts #'s.. Be careful, my dealer said all parts were no longer available....he was wrong! Motherboards are a bear, I believe my model has 3!Most techs are not familiar with Samsung and will not be able to correctly diagnose the problems, mine came out and said it! "We do not Know and the factory will not give us any idea what the problem is" We're sorry! That was 3 month ago, and now I have a beautiful yard fixture! a $1400.00 yard fixture!! hope this helps someone..

SOURCE: 5 year old Maytag Wide by Side Refrigerator side not cooling

Same issue with my 6 yr old Maytag side-by-side model #MSD2756GEW. Turned out it was caused by a faulty circuit board. This circuit board is located in the upper right fridge section. Apparently these boards are sensitive to power surges (which we have here in central Texas from time to time.) When the circuit board is fried, it makes a noise like a fan blade malfunctioning and it stops the auto defrost feature in the freezer from working. So the freezer ices up at the back, and the ice prevents the cold air from reaching the fridge section.

Our circuit board (which we thought was a fan) made ominous noises for a few months. (The noise would last only a minute or so and stop shortly after we opened a door). Eventually we noticed that the fridge wasn't as cold and the freezer had snow in it. Finally the board stopped making noise and about a week or so afterward we noticed that the milk had spoiled and the fridge wasn't very cold. The food in the freezer side pretty solidly frozen, thankfully.

In addition to replacing the circuit board, the fridge had to be de-iced or it would not work properly. I put it all frozen into a large camping cooler where it stayed for several hours. I opened the freezer doors and put table fan and pointed a hobby light which gets quite hot, at the back of the freezer. Within 3 hours, the ice had melted significantly so I could see through the grate at the back of the freezer. This really great technician named Tracy, made a special trip to the parts store to get the circuit board and came back within a couple hours, bringing with him a steamer. He removed the back panel inside the freezer section (the coils are behind there) and used the steamer to melt the rest of the ice before he left.

Tracey, who works for a local appliance repair company, told me that about 4 years ago, Maytag started making their fridges with built-in surge protection, so the circuit boards apparently don't get fried on the newer models as they do on my 6 yr old model. He recommended that we put plug the fridge into a heavy-duty surge protector - which we are definitely going to do.

I had the same problem. I found the buzzing noise was caused by ice build up around the fan motor inside the freezer. I believe water must have leaked down around the fan during a defrost cycle. I removed the ice maker, the ice cube bin and ice dispenser auger motor. It sounds complicated, but it isn't too bad. The ice maker and auger are connected with quick connect plugs. So just unplug, remove the screws and remove them from the freezer. You will need to remove several other screws as well, I believe 11 in total as well as the top freezer rack. This will give you access to the white aluminum panel that runs from the top of the freezer to about halfway down the back of the freezer. After you remove the aluminum panel you will see the fan about half way down the freezer. I found a lot of ice around my fan. The fan blades were hitting the ice causing the buzz. Remove the ice and the buzzing is gone. It took me an hour to complete this repair. I hope this helps.

SOURCE: REFRIGERATOR IS MAKING A BUZZING SOUND, not cooling

You have one of two problems going on. Your fan is spinning at hitting the sides. Or your compressor is shot which seems to be more the problem and even though it is cold the humming sound is a warning for you that the compressor is shot and it is more affordable to replace the fridge then the compressor. Sometimes compressor can cost more then the fridge.

Testimonial: "It was the compressor. Bought a new Amana and it's great! Hate Sears still;)"
