It turns on and off frequently, which might damage the heating/conderser
Either in cooling or heating mode, after reaching the temperature I set, it keeps off for about 5 minutes. Then it switches on again and keeps on for about 5 minutes and switches off. However, after keeping off for about 5 minutes, it switches on again,....... It seems that suck kind of situation might damage the heating/cooling system. Especially in cooling mode, it might result in the heat protection inside the condenser in hot summer.

Some thermostats allow you to change the differential value - that is how far below the heating (or above the cooling) set point before calling for heat (or cooling in the case of air conditioning). The built in 1 degree differential setting provides the most even temperature in the space at the expense of more frequent furnace firing and stopping. Many people prefer this mode as opposed to allowing wider swings in temperature for less frequent furnace firing and stopping. If you wish to change this setting, you'll need to replace the thermostat as it is not user adjustable in this model.
My name is Peter. I am a retired field service refrigeration technician.
The model number provided does not register. Your model number is located on the inside wall of your fresh food section.
Your freezer is your only source of cooling. It will meet its setting before meeting the refrigerator temperature.
The normal setting are -2 to +2 degrees F. for the freezer and 35 -40 degrees F. for your fresh food section.
Your freezer will go about 10 degrees F. above the set temperature. Then when it reaches 10 degrees F. below the set temperature the compressor will kick in.
You have condensing coils either under your unit or a canister in the back which gets ride of the heat. When the condensing coil is plugged up with dust, this could affect your cooling by as much as 40 degrees.
I do not think this is your total problem.
Feel the face of your separator wall between your freezer and fresh food section. Is it hot?
Your problem is your condenser fan in the lower right back of you unit is burned out.
So, you can not dissipate the heat.
Remove the lower back cover. Take a common household fan to blow air under your unit.
Your compressor is running to make up for the heat that the condenser fan can not dissipate.
Make sure you have set them correctly IE/ If you want them to heat, make sure the heat symbol is dispalyed and the temperature setting is above the room temperature. Press the "house" symbol on the remote to find the room temperature. LG as with most other brands , if set to cooling but the remote temp is set high ( 20 to 25 degrees,) will run for a few minutes and then turn off as the machine thinks it has reached the temperature you have selected.. Heat symbol on LG is a "sun", cooling is an icicle. Check your filters.... if they are dirty, the units will not operate correctly.
I have a honeywell TH8320U thermostat and American standard Air handler with heating unit put in. THE thermostat works fine with the ac and follows the programs I have set. However the heat is a different story. The thermo clicks on to follow program but the unit does not run. (auto settings) If I place the thermo in heat and turn it to on I get heat?
The ECO HEAT/COOL button of your hybrid functions to reduce the consumption of electricity thus, a reduction of fuel consumption. An indicator 'ECO' appears on the air conditioning display to indicate that the mode is on. Of course, with the ECO HEAT/COOL on it'll take longer than the usual amount of time for the temperature to reach its normal or standard set temperature.
Your ECO HEAT/COOL mode won't function if your temperature control is set at 'LO" or 'HI" or if the air flow is in the "floor/windshield mode" or "windshield mode".
If you have a standard thermostat the fan switch is for the air handler only. It completely over rides the thermostat for most settings. Now lets see this is what I'd expect: fan switch on Indoor fan runs all time Fan switch auto Indoor fan only runs when thermostat is set to cool or heat and the thermostat is turned up above room temp for heat or below room temp for cooling. In both of these modes the furnace blower comes on and stays on til the room temperature is satisfied. The outdoor unit only comes on for AC the out door unit will not come on for heat or the "on" setting on the thermostat. See exception 1 & 2 below...
Exception 1- (in a heat pump the out door unit runs in both heat and cool mode
unless it has emergency heat turned on then it will not come on outside
in the heat mode, and depending on the type of heat pump and furnace or
air handler it is). A heat pump thermostat usually has "backup heat" and an "emergency heat" setting switch on the thermostat. Exception 2 - On some thermostats they are made to cycle on the heat if the temperature reaches a preset temp (around 50'f usually but definitely by 40'f). This mode prevents freezing when if instance the homeowner is away or while the home is under construction. In this mode the fan inside can run but the heat usually comes on with it. Exception3 - On some electric furnaces the heating strips may be individually controlled and thus not all come on at one time. This may give the feel of no heat especially if the room is cold.
Now there may be other exceptions but Ive tried to give you a heads up on some of the most common ones. If you need more help please post more specifics about your unit/system as to for sure what switches are set to what setting and what is happening with each. My first though was that maybe your system is OK and you needed to know if the thermostat was working properly.
If this helpd you understand your problem would you please give me as hifgh a mark as you can. Thnaks for using fixya and good luck.
