![]() To check if the start relay is faulty, detach it from the compressor and shake it vigorously. In case of a faulty start relay, it wouldn’t start the compressor, and the fridge won’t cool properly. Start RelayĪ start relay is a small black box attached to the compressor that turns on and off during the cooling cycle to maintain the overall temperature of a refrigerator. So, using a multimeter, check the continuity of the temperature controlling thermostat and replace it if it indicates some fault with the component. If you frequently adjust the thermostat settings to alter the inside temperature, then its overall resistance or continuity changes. So, a thermostat malfunction means none of the refrigerator components receives the appropriate voltage to run, and the refrigerator can’t perform its cooling operation. Temperature Control ThermostatĪ thermostat in a refrigerator regulates the voltage of the entire cooling system, viz., condenser fan, ice maker, compressor, and evaporator fan. If the multimeter indicates there’s some fault with the components, replace both. And if the issue still persists, you should check if the evaporator fan motor is working or not.Īpart from that, it’s essential to connect the multimeter with the evaporator fan and fan motor to check for their continuity. ![]() Take a soft brush to clean off any dirt from the evaporator fan blade, and in case it has jammed up pretty bad, you should also use hot water along with the soft brush. If objects become entangled or dirt accumulates in the evaporator fan, your refrigerator is unlikely to cool properly. Evaporator FanĪn evaporator fan distributes cold air from the freezer within the entire refrigerator. Again, check for continuity of the fan motor using a multimeter you need to replace it if it doesn’t show proper continuity. If the fan blades rotate freely, it’s time to survey the condenser fan motor. On the other hand, if any objects have become entangled, remove them so that the fan runs freely. In case the dirt has jammed up the fan to the point of no return, it’s time to replace it with a new one. It might be due to the deposition of dirt, or something might have become entangled in them. Condenser FanĪnother reason your condenser may not be cooling is that the blades of your condenser fan are stiff. Just make sure to dry the condenser unit properly before powering the refrigerator. But if the dirt has solidified, use a brush and warm water to get rid of it. Then, use a small and soft brush to remove dirt off the coils. Get to the back to unscrew the rear access panel at the bottom, where you’ll find the condenser coils. To start, unplug the refrigerator from any power source, disconnect the water supply, and move it away from the walls. The deposited dirt doesn’t allow heat to dissipate from the refrigerant, which travels into the fridge and affects its cooling ability. If the condenser coils of your refrigerator are dirty, it will stop cooling. There can be many reasons for a fridge or freezer compartment not cooling, some of which are mentioned as follows: 1. Problems With A LG Compressor And Its Solutions A. Otherwise, it’s best to call in expert technicians who can identify and resolve the issue fast. If you’re well-versed in the nitty-gritty of using multimeters, you can check the compressor for faults easily. ![]() So, if your refrigerator compressor is showing similar irregularities, it might be time for a checkup. In case the compressor has some problems, it runs continuously without stopping or doesn’t run at all. The refrigerant further flows into the compressor, and the cycle continues.Īs a result, a compressor only operates when refrigerant enters it. It then moves through a metering device before entering an evaporator to cool and return to its original gaseous state. ![]() Pressure is applied to the refrigerant as it passes through the compressor and turns to liquid when it reaches the condenser. Check For Irregular Operationīefore understanding the issues with a compressor, let’s understand how it works. Although a compressor gets hot while running, overheating isn’t a good sign.ĭo remember not to touch the compressor with your bare hands, as you might get burned. If it feels hotter than usual, the compressor might have some issues. Keep your hand on the compressor for a few seconds. Keep listening to the sound for at least 30 minutes if you don’t hear the familiar pattern, you might have a faulty compressor.Īlso, if it cycles on and off very often, that might also be a sign of malfunction. Listen To The SoundsĪ perfectly-running compressor toggles between on and off and makes a humming noise while running. Here are a few signs to warn you that your LG linear compressor fridge isn’t in good shape or not working properly: A. 5 Final Words How To Tell If A LG Compressor Isn’t Working Properly? ![]()
