SOURCE: lg split indoor fan runs non stop

Hello Hamid,
The unit is designed to run the indoor fanmotors continuously when in cooling mode on both indoor units (evaporators). The reason is that this circulates the air and the temperature thermistor or sensor is able to sense return air temperature and in turn start or stop the outdoor unit and compressor as required according to the setpoint temperature. The reason for either unit not reaching setpoint temperature can be a couple of reasons. A) Incorrect design - the unit may be too small for the application. You can calculate this roughly at 650BTU per square meter of room in a relatively warm ambient climate. Or secondly B) The outdoor unit has leaked and is short of refrigerant. You can check this when the outdoor unit is running by feeling the thicker copper tube on the right hand side of the unit. This should be cool to cold. If no temperature difference is felt, it is short of refrigerant. Hope this helps you. Goodbye

SOURCE: ice formation in the indoor unit

you need to have the unit checked for the amount of freon in the system this must be done with a gauge set the freon amount is obviously incorrect
also the a-frame evaporator must be sealed in the furnace cabinet

How many blinks look at the diagnostics troubleshooter usually on the panel of the unit, then determine the problem.

Maybe you need to invest in a good De-Humidifier.

Why does the compressor run only for about 5 minutes then shut off, leaving the fan still running?


It seems that you have a system short. You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset.

If this doesn't help I would recommend calling a ac service company.

Problem with GE PTAC-Model# AZ28E09DABM2 - Why won't condenser kick on when switching to AC from Fan. AC was working fine until today...Fan is still working...Pulled the unit out and could feel the h


Hummm. A bit difficult to solve this problem. Seems like the condenser outside is not working, I mean the fan of the condenser. Looks like you have a wall A/C and a wall A/C always have condensers outside the house and near the A/C. Have you checked if the fan is spinning? I don't think the compressor is at fault but check it anyway. You should be able to hear the compressor running either in the wall unit or in the outside condenser housing. The only heat you should feel is from the condenser itself. If you blows warm air, that means the fan is working, if not that means the fan is not working. But don't be confused with the fan not working because in winter time sometimes the fan is not working and some times it does. As I said, it's a difficult problem to solve but at least start with checking the situation with the fan in the condenser.

Kenmore AC window unit model 253 70151 cuts on and off.


Circuit board could be the problem but compressor needs to be checked and there might be a loose electric connection or high voltage causing the ac to trip

Refrigerator wont run. Clicking noise coming from main board preceded by a short humming noise every several seconds. Unplug for 30 minutes then plug back in and compressor starts up after several clicks...


Hello,
That condenser fan motor needs to be replaced. You and doing the right thing as far as using a seperate fan to keep compressor cool,buy replacing the fan the compressor will run cooler and click off by being too hot as you have heard/seen.

Find your model number and call your local appliance parts store and see if they have a CONDERSER FAN MOTOR in stock

My volkswagon beetle is running hot and has a knocking noise when you put in drive


Is the knocking noise can be heard if you have neutral on and accelerate and decelerate the engine?
The running hot could be several things but the basic ones to look at are if the radiator and condenser are dirty and if your cooling fan coming on when the engine reach tempt for fan to kick on. You have two fans. the second to the right is for the AC when the AC is on which should run as soon as you turn on the AC. The left fan, driver side in engine compartment, is the one that works with the coolant tempt sensor.

Ac unit clicks outside but nothing engages fan or compressor on unit furnace still runs for heat setting and fan still blows but ac will not engage just hear a clicking was running for three days this...


Have you check the outside breaker? If its ok then you got a problem in your electrical system inside the unit probably the contactor is not engaging this is where the 24 volts from the thermostat calls for the 240 volts to run the condenser fan and compressor. Be careful checking this out because of the high voltage.

It sounds like your condenser fan motor may be locked up or the capacitor that helps give the condenser fan motor a kick to get it started may be defective. Try turning your system on and using a long screwdriver try to push the fan blade on the condenser fan motor to see if it will run normally if you give it the starting boost it needs.If it does run at full speed and doesn't over heat or start and then slow down then you probably only need to replace a simple 10-12$ capacitor. If it barely turns, makes an odd humming sound or overheats etc. then you will have to replace the condenser fan motor. This is assuming that the outdoor condenser has the 220v supplied and the 24v supplied to the compressor relay, that the compressor relay is engaged and suppling 220v to the condenser fan motor.

Control panel lights blink and beep, freezer fan cycles


The column between the doors being warm usually indicates that the compressor is running properly but the condenser fan at the bottom rear that cools the condenser and compressor is not running. Remove the cover from the back of the machine and verify this fan is running. It could have stuck from sitting for a period of time or something has gotten stuck in the blade during the move.
I am interested in what the fan inside the freezer is doing. You say 3-4 second pattern, is it running a few seconds then off a few seconds?
Please post back with the exact model number from the decal inside the fridge and I will look it up and see what I can come up with.
