I have the same problem on my Samsung fridge (RS253BASB). I just had warranty work done, they put in a new evaporator two days ago, and now the outside of the freezer wall and the inside divider between...


It sounds unrelated to the evaporator change unless they were working behind the unit. The evaporator is in the freezer. I think you're having a condenser fan problem which is around back behind the cardboard cover. It should be running when the compressor runs.

If the clicking is coming from the electronic control then it is the problem. It controls the fans and defrost etc. It's part 27 on this diagram.

Compresor wont start and when it does it cycles on and off


Does the condenser fan come on? I am assuming the evaporator fan (inside) is blowing? The way these units are wired is that the power goes the the inside unit and the controller inside sends power to the compressor and condenser fan. But if the controller detects that the condenser fan is not turning (via no ground return) it will not send power to the compressor. This to protect the compressor. Did you notice it trip a breaker? When it is on, do you have 240 on the unit outside but not 120 to ground from each leg?

Fans inside freezer will not turn - no cooling - compressor fan underneath is turning


The fans are controlled with a clixon that has a cut in at 5 degrees, and cut out at 20 degrees. If the unit is running and the fans are not comng on then I would have to say you are out of freon. But your condensor fan could be running and the compressor NOT be running which could be a problem with your compressor. Find out if your compressor is running by taking an amp draw. If compressor IS running then you are low on freon. If the compressor is running and your evaporator coil is cold and your fans AREN'T coming on then your clixon is bad.

Avanti Beverage Cooler BCA5105SG running very loud.


Inside the cooler is the evaporator fan usually right in the middle behind a cover. As it slows down you have less circulation and ice forms quicker and cooling is diminished. Sounds like it is going out.

Refrigerator has a clicking sound and does not run


Replace the motherboard (part # WR55X10942) but be careful to check that the evaporator fan (inside the freezer) turns on when you power up the refrig again. A bad evaporator fan motor can take out the motherboard. If compressor starts with new board but not evap fan, unplug immeadiatelly and replace the evap fan motor to save new board.

Outside fan does not spin and a loud screeching sound coming from


Hey there, sounds like the bearings seized in your fan motor. You need to replace the fan motor. If the compressor runs without the fan, th pressures build up and if they reach an extreme point, the compressor will bypass internally, creating a loud sound as the high pressure is released to the low pressure side. I would turn the thermostat on and stand by the outdoor unit as it start. Leave the disconnect on the wall readily available so you can quickly turn it off. If the compressor sounds ok when it starts up and runs for a couple seconds, turn it off right away and replace the fan motor and you should be good to go. If the compressor sounds bad or real noisy immediately at start up, the fan motor not working killed your compreesor. You would need a motor and compressor, might as well replace the unit at this point if you are paying to have it done. Let me know if you need anything else

Have a near new panasonic cs-e28hkr split system air conditioner and the outside condensor fan continously runs even with inside unit is turned off? Thanks


Sir/madam,
If the inside unit (evaporator) is turned off absolutely.
The condensing unit must be turn off outside because the power
are derived comes from the evaporator.
Possible it seems on the cut out stage inside and remain the power still on
Otherwise theres somebody tamper the connection?

Fan cable consist of 3 wires
1 Common line
2 Start /stop line***Change the connection of this wire where it located, To On/ Off switch of the
evaporator inside unit
3 Ground green line/Earth

note: you can get all that wires inside the power supply in evaporator area.

If still under warranty inform the manufacturer

Loud whistle noise kelvinator split KSR25F-01


It may be the small vent fan motor on the inside if the control panel. When the noise begins remove the panel and you may be able to catch it in the act.

Loud Popping Sounds


If this is a heat pump system it is possible that your fan blade is hitting ice on your condenser coil.
