LG LFX25991ST Linear Compressor Frig has started making a noticeable audible (vibrating?) noise.

There are instances where the compressor can come loose inside its housing. That is not an indication that it is going to totally fail and it has no effect other than the noise. The fan noise would be louder inside the fridge. It would be a squeal.

ARe the linear compressors in the Kenmore equivalent to the linear compressors in the LG refrigerators?

Hello David,
  • Yes, Kenmore Refrigerators use LG Compressors.
  • There are two types of controllers used in the linear compressor system.
- The "E"-inverter system is used with the FC75LANE compressor.
- The "A"-inverter system is used with the FC90LANA compressor.
  • The two types are not interchangeable because the FC75LANE uses an Inverter CVCF (Constant Voltage Constant Frequency)
and the FC90LANA an Inverter VVVF (Variable Voltage Variable Frequency)
Here is a link you may find helpful.
Good Luck,

I am having a problem with Xantrex DR1512 inverter which I have connected as power backup to support house lights and appliances during power outages, the problem is the inverter output flickers and...

It sounds to me that the inverter is working fine, just undersized. Motors consume a LOT of power when they start. A fridge compressor could draw as much as 800W when it first starts up.

Compressor won't engage-water was shut off and on to house when away-no symptoms before-

no you need a new ptc overload relay thats mounted on the compressor it aids in starting and running the compressor

Cooling system of my LG frostfree refrigerator is not working for the last two days .No one is attending the complaint from service center , Panvel Navi mumbai . Need immediate help/

5 reasons for fridge and/or freezer getting warm: 1- the evaporator coils are icing up and won?t let air circulate. 2- the evaporator fan is not working to circulate air. 3- there is no refrigerant in the system. 4- no power to fridge or compressor. 5- the condenser coils have no air circulation check under the fridge behind the vent. if it is too dusty or the fan isn?t working, it is not getting enough airflow to cool down. replace fan and/or vacuum out the dust. if there is no power to the fridge, the light will be off. if the compressor is not running, there is a defrost timer that cuts the power temporarily to the compressor to melt ice on the coils. it?s located under the fridge behind the bottom vent. If the timer is off and the compressor is not going, the compressor or the main board is bad and needs replacing. there is also a temperature sensor on the evaporator coils that tells the defrost coil to turn on and when to turn off. if the defrost timer is on but the coil is not heating up, replace the sensor. if it still won?t heat up, it?s the timer or the coil. the easiest way to tell if there is no refrigerant- the freezer wall is warm and the compressor is loud. if there is no refrigerant, it may be more cost effective to replace the fridge. if you feel no air coming from the freezer vent, the fan needs replacing. If you feel air moving in the freezer but not the fridge, the channel from freezer to fridge is blocked. if the freezer has air and the rear freezer wall has frost on it, the evaporator coils are iced up and need defrosting. causes: 1. low refrigerant 2. no fan 3. too much humid air in fridge/freezer due to door open or bad door seals 4. the condensate drain tube is clogged if the seal around the door is ripped or not completely sealing, or there is condensation at the bottom or the walls of the fridge, replace the seal(s). no air, no fan. Replace if the refrigerant is low, it just needs a top off. but you need to be certified by the epa to move refrigerant, so get a professional. defrost solutions: unplug the fridge. remove the wall of the freezer that is frosted/icing up. use a hair dryer to melt the ice. do not get too close. you will see a drain under the evaporator coil. make sure it is not blocked. the water should run freely to a condensate pan under the fridge that evaporates the condensation with the hot line from the compressor. once the coil is free of ice, frost, and water, replace the panel and repair any of the problems that caused the icing up. plug the fridge in and turn it on. If it frosts up within a week, there is still an issue that not been taken care of.
