My fridge starting after some time stopping and not starting it self unless switch off power supply and then on it will again in auto


AT TIMES YOU MAY HEAR THE COMPRESSOR CLICK OFF AND ON OVER AND OVER. Signs of a bad start relay or capacitor. Check with an OHMS meter for continuity (ohms) and voltage, capacitor can be checked for Microfares. ( if in series with the windings)
To check ur compressor with multi meter:
Disconnect and remove the relay and capacitor from compressor, somes located next to compressor in a casing.

You wills see 3 prongs coming out of compressor. 1 goes to ur start winding, 1 goes to ur run winding and the center goes to ur ground or COM

Place ur meter connector or prong on the start prong and the other on the ground (center prong) take note of the reading in OHMS for example 5 ohms.
Next place meter prong on run prong and the center ground prong agin. Take note of the reading in OHMS. Example 4 ohms

Next place meter prong on the start prong and the other on the run prong, now take note of the reading example 9 ohms. Now match the total of this ohms test with the total of ur two separate test. 9 ohms, if they match ur ok give or take 5 percent plus or minus. One more test to make to test of there is a short in compressor attach meter prong to ground prong and rub the other end of meter prong to metal ( scrape the metal clean of paint and test on metal surface not painted surface. If it shows continuity or ohms , u have a short in ur compressor. It should show infinity

Makes a clicking sound about every 12 mins but is cooling okay and sounds normal


THE COMPRESSOR:
If you hear a clicking sound coming from the back of your refrigerator/freezer, then the problem is most likely the compressor, relay and or capacitor is overheating or not getting proper power and will not start.The compressor is the component on your refrigerator that allows your refrigerator to cool. If this component is not working properly your refrigerator will stop cooling. Most of the time the compressor is not the component that has failed.

To check ur compressor with multi meter:
Disconnect and remove the relay and capacitor from compressor, somes located next to compressor in a casing.

My lg gm-313sc keep on work and stop in lest than 3 minits


The refrigeration is short cycling. The cause may be due to airflow problem. There is an outside fan thalt blows across a radiator and another in the inside the fridge enclosed behind panels.
These two fans must run and blow across the refrigeration radiators. The outside one can clog with lint and dirt, the inside one can clog with ice buid up, or the fans simply quit working. Check that the fans run and that the radiator coils are clean and clear to airflow. For the outside one, paneling will need to be removed, as well for the inside one if the outside one does not do the trick.
The refrigerator compressor short cycles because it overheats. The cool refrigeration gas entering the compressor cools it and when the gas is not kept cool, the compressor may short cycle.
There may be a different problem but checking for airflow is a start.

Once you turn on aircon with fan with high speed, the air blown doesn't get cold even after a while. The fan makes some wierd high pitch sound as if like metal against each other. The fan stops once in a...


Your AC needs a good overhauling as the fan seems struck on the bearings or the blades are rubbing the sides. Also the compressor fails to cool as there can be low gas, low pumping pressure or a blocked condenser.
You need to remove clean the coils and lubricate the fan to be set back. Check the capacitor to the fan and compressor as a low value will reduce the speed and so reduce pumping pressure.

I have a Carrier Aircon. Model 42QH12-C and it is displaying error code 5. The aircon stays on for a while (anywhere between 10-60mins) and then turns off and displays E5. If I just press the 'on/off'...


E5 Outdoor activation of compressor over heatprotection or motor lock

Please clean the condenser coil. And also check out door fan motor rpm. Rpm may be less due to weak capacitor. Replace it.If motor locked you have to replace new motor only.

If helpful, please write.
