This is literally happening to my fridge at the moment. These fridges are extra sensitive unfortunately.
The back wall on mine has a layer of ice build up, and thinking back on recent events, I cleaned out all of the shelving and doors recently while leaving it turned on and door open for quite a while. Impatience on my own part. This has made the fridge work overtime to keep it cool, and over frosted it. Because these “babies” are so sensitive, the minute you forget to treat it like a baby, it plays up! Lol

Also, sometimes in the hotter weather, continuous opening of the door and leaving it open for longer that necessary, (which my granddaughter does frequently!) does not help the situation either. Lol
This would have most likely made a layer of ice build up along the back wall, which in turn, has interfered with its normal cooling system.
So, to fix this, I would turn the fridge off at the power point, cleaning the ice off from the back of the fridge wall, and anywhere else it may be.
Also, make sure that the drain hole is clear of debris while you’re at it.
Dry the wall off with a hand towel or some paper towel as well.
After that, put things back in place making sure nothing is touching the back wall, let it sit for about 1/2 hour, and turn it back on. Hopefully this will help the cooling system get back into it’s rhythm again.
TIPS:
Find the best time to do this.
I would do it when the fridge is at its emptiest. The day or night before you go shopping. If you can, leave the fridge turned off for a good 1/2 hour if you can. Put your items in those shopping freezer bags with ice cubes or an esky if you have one, to help keep the fridge items cool. Most of your fridge items would be fine in the freezer for 1/2 hour as well.
Hopefully it’s a simple fix like this one.
Best of luck

Hi Tarnee, I have had the same problem with my fridge, but I haven’t delved into solving the issue with it yet. I get by without the light and alarm working, which doesn’t bother me at all, so I’m being a bit slack on getting on with fixing it. The alarm and light will eventually just turn itself off after 5-10 minutes, then it should be fine after that. With fixing this problem and having it working, I haven’t reached that solution as yet, but now someone is asking, I should get back to having a look at my fridge again. It still works just fine without the light and alarm, and when the power has been disrupted and turned back on, it just beeps for 5-10 mins, then it’s quiet again. I’ll get back to you with an answer as soon as I check out my fridge and hope I can get you some answers.
