About 3 weeks ago we heard a loud noise when the compressor starts. Today it made a different noise and it went quite after that and then we noticed the temperature drop.
Is it the compressor went bad?

Re: Temperature at 10 degrees
Check condenser fans, if defective or running slow change it
if condenser fan is running, suspect a compressor with internal mechanichal problems, it will run but i can't guarantee how long, maybe a couple of weeks or days. if it's an copelamic compressor, it's going bad.

20 years ago guys used to put a 50 watt bulb down in the compressor area BUT the freezers today have been designed with the condenser in the freezer wall and don't retain any heat in the cold weather. Generally what you will experience is the temperature in the surrounding area drops to 10 degrees the freezer goes off and when the area begins to warm up the compressor tries to start with syrup for oil in its crankcase and cycles on its protector until it gets hot enough to warm the oil and allow it to run. Compressor life is shortened and the freezer temp is unstable. A self regulating crankcase heater could be purchased at a local supply house and wrapped around the compressor but I don't know if its ever been tried on a compressor that small or if you might overheat the compressor. ............Can you say garage heater? Its a matter of system design. All of the components for a commercial conversion are out there but a system that small is never considered. Sorry wish I could help more. Hope this helps and good luck.
This kind of noises produced gas in cooling system.
In the old coolers never heard sounds like streaming water because the compressors were very loud due to high pressures (12 bars or more), which were required for efficient cooling. Today we use more ecological gases which work (from 5 to 6 bars) at much lower pressures, thus compressors produce much less noises and now suddenly we hear sounds that never before heard. Generally speaking noises is lower, measured in decibels.
Hi Julie. I'm Roger. It sounds like the operating thermostat is not working When not in the fast freeze mode. Can you here a click sound from the thermostat when turning the temperature up and down short of fast freeze? We normally charge them to operate at -10 to -20 degrees. The inside temperature will normally only reach a temperature around 18 degrees warmer. The operating thermostat should allow you to regulate its temperature any where from that capability up to where you want it. See if your thermostat makes a clicking sound when adjusted. The warning light comes on because it knows the box temperature is higher than it is set for and is warning you of that. If it uses a printed circuit (PC) board, the click will dot be very loud. listen closely. Let us know how this turns out for you. We have very good refrigeration techs. here. Someone else here may have an idea too.
it is not defrosting. timer ,element , limit switch maybe issue. find defrost timer advance it see if compressor and fan quit running. when you advance this it should start defrost mode, which turns on the heater, which stays on till limit switch opens or timer advances, most are on 12 hour cycles
Totally a normal action.. When the compressor switches off once the temperature is reached, or possibly after a defrost cycle, if the gas hasn't quite equalised, it will click once or twice then start up.If the compressor has a starting capacitor and it does the clicking, then one needs to check the capacitor.
Yes it is a very big concern.It sounds to me like your condenser is dirty and the compressor gets hot and goes off on overload.You can tell by putting your hand NEAR the compressor.Be careful as the compressor can be very hot
Hi, As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong. If you are hearing a clicking or buzzing then check out the last two tips. If your refrigerator is running but warm, then… Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...
If you hear this noise when the unit shuts off, you might even feel it vibrate the floors. This would be a compressor that is on its last leg, I would start shopping, but you are in no immediate rush, unless its happened for quite a while.
