Re: Re: Magic Chef
If the compressor is running but the fridge is not cooling, the gas may have leaked out of the system or the compressor is inefficient. The only way to know for sure is to connect a set of gauges to the system. You will need to call in a Refrigeration Mechanic.

My unit is a 3 year old Mitsubishi and it started making the humming noise you described. It is quite high and I finally got up on a ladder to have a look. It is the water pump making the noise in my case. It seemed like it was pumping a little too much water out. I undid a screw and angled the pump slightly and problem solved.
hope this makes sense and helps a little.
Hi, The noise is the fan hitting ice build up on the coils... it is no defrosting properly...
Check out these tips...they can help you figure out whats going wrong with yourrefrigerator and why it is not cooling
Mine is a different model, and less than three years old, but the vibrating noise was really annoying. I would shift the unit or the door slightly, and it would stop for a while, as you reported. I took a few minutes, applied pressure to different areas, up and down, inside and out. The noise was louder near the floor. I removed the plastic grill and applied upward pressure on the wires covering the coils - it was loose. I noticed an accumulation of dust, and vacuumed as far as I could reach around the underneath area; also pulled fridge out and vacuumed a dust-covered vent on the back near the floor. Was planning to insert some kind of wedge under the loose part, but when I put everything back in place, the vibration stopped - now I only hear a gentle hum. Seems I did something right in this process.
compressor is a football-sized case with no apparent moving parts. It's
on the outside of the refrigerator at the back near the bottom. If it
is humming or making a continuous noise and your refrigerator is still
not cooling, there may be a more serious problem with one or more of
several different components, we recommend contacting a qualified
appliance repair technician for further help.
If the compressor is not running but you do have power to the refrigerator, there may be a problem with one or more of these:
Sounds like the freezer fan is rubbing some wires or possible some foam insulation around the fan. I would look into the freezer compartment fan and go from there. The fan Will Shut off when you open the doors. Let me know how you make out and if you need anymore help.
