Mode Switch Problem

The "Mode" switch/button on my unit has stopped working. I was cycling from Cool to Dry and it stopped on Fan, so now the unit won't cool. Is there a way to clean or replace the switch, or do I have to replace the whole unit?

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: what is the function of dry mode in ac

Dry Mode in AC is to dehumidify the room the fan cycles on and off and the indoor unit temperature drops below freezing which causes condensate to collect on the coil and as a result the humidity level of the indoor air is reduced

SOURCE: My LG Lan125HV works fine on air conditioning (

I talked to LG customer support (800) 243-0000. The tech told me that this model had a problem with the indoor thermistor. It doesn't fail with an open-circuit condition, so you don't get an error code. The thermister just goes out of range and believes your indoor temp is much hotter than it is. That's why the heating never comes on. I'll bet that, even though it ran in COOLING mode, once your room reached setpoint, it just kept on cooling & cooling ... because the thermistor was still giving a false, high temp reading.

So, I bought a new thermistor, P/N 6323A20042A. My unit worked fine. Until the next week when I turned heating back on and now I have the same problem ... gives cooling but no heat. Something is failing the indoor thermistor OR the distributor sent me an old-style thermistor, I haven't gotten determination on that yet.

Regardless, call LG and see if they can't direct you to a distributor for an indoor sensor. LG's warranty coverage for parts is a royal pain, unless you can show a receipt by a certified installer, you're not going to have much luck getting payment for the part. However, the thermistor is only $10. Just hope you get one that doesn't fail on you!

on a call for air conditioning your therrmastat brings the indoor fan on and the out door unit at the same time. Since your fan comes on in "fan" mode, it sounds like you need a thermastat. For temp. cooling just turn your fan switch to "on" and turn system switch to cool and set desired temp. System will cycle off and on but fan will not shut off until fan control is set back to "auto". I suggest replaceing thermastat

Sounds like the switch is wired wrong.
When you put the switch on fan only the compressor should not run at all, therefore their shouldn't be any cold air.
Check the switch to see if it's wired right.

Will not switch to cool mode. heat and fan work fine


hi,
regarding on switch mode theres a common line between heating and cooling although fan is always connect on them.,also with the thermostat,the sequence on this when you switch to cooling and your connection is on heater,the contactor will shift to compressor source,so if there is no cooling, the contactor supplying the compressor is not functioning when you switch on cool mode.try to tighten screw on compressor relay maybe only loose.on control panel,or check continuity of compressor if the compressor still good,check also the freon charge using clamp ammeter,this should be done by ac technician.have a nice day
rate me up,thank's

Fan runs constantly on cool mode


Simple Question: Did you check to see if the fan switch on the
t-stat is in ON or AUTO? If ON the fan runs nonstop. If in auto the fan cycles with the outdoor unit.
next does the fan shut off if you turn the t-stat to off?
A stuck relay should keep the fan running all the time.
Sometimes if the relay is stuck you can whack the side of the Air Handler and the connection will break.
Sometimes instead of a relay there is a stack switch.
It's a little black stack of 3 disks this is a bi-metal switch.
they do get stuck more often than relays.
The fan relay may be on a electronic board. I don't know for sure without seeing your unit.
Good Luck Phil
