Compressor working fridge is not

Question edited for clarity, MAKER.
Question moved to Model Category.

Your fridge freezer has three fans.

The compressor evaporator fan cuts in and out as required to maintain temperature.

The fridge evaporator circulation fan runs to maintain an even temperature. It stops when to open the door and resumes when you close it and stops when the set temperature is reached as long as the compressor isn't running. If the compressor is running, the fan normally runs to prevent icing which happens slowly.

The freezer also has a fan, and that runs pretty much all the time unless target temperature is met and the compressor is not running. This fan runs when you open the door to stop the moist air from the room freezing on contact to the 0'F, -18'C evaporator fins. The fan keeps the air moving to deposit less frost.

It sounds like your is running normally except for the noise. Trace the noise and find it. The compressor fan has a Shark Paper fibre board cover and these often distort over time and touch the fan blades. That is the common cause. The less common cause is the internal fans pinging off built up ice that should have been removed during the defrost cycle.

hello sir

normal if it is the outside surface that is warm
as that is the condenser exchanging the heat through a panel
the compressor will run for a period until the heat inside the compartment is brought down
Experience has proved that to get any fridge /freezer to work well , place a bowel of water in first as that gives a heat source to cool down and it will do so more quickly that just an empty volume

have you checked the door switch for each door? the lights should still work in defrost mode but not fans or compressor.

Check power to compressor through thermostat. If compressor running but not freezing, suspect refrigerant leak. If sides are warm to touch, check to see if a fan is present in the compressor compartment on the side/rear and check it's working.

ok well... those pipes coming from your compressor one of them should be hot. if not your compressor is not running.

Replace the start relay on the compressor.

If the fan motor is running at the compressor you should first replace the compressor start relay.
If the fan motor at the compressor is not running replace the defrost control.

If you checked the fan and for ice on the back wall (for defrost problem) Then you most likely are low on freon or you have a bad compressor. Check to see if the compressor is running (IF scorching hot its bad too) . Next check to see if the coils under the unit are hot. They should be so hot you cant hold onto them. Just touch for a second. If they are just warm, then you are low in freon.

It should work the same as before. Does the compressor get really hot after running a while? If so it could be low on charge, or there could be a restriction inside the refrigeration system. Either way a professional would have to look at it.
