Heating problem with one split in a double split system

I have a double split system and until yesterday the heater was working perfect. Now in one room in heating operation the indoor fan doesn´t start (operation indication lamp ON). Cooling and Healthy Dehumidification operation work properly. In the other split all operations are working normal. What could be the problem? May be the main PCB ASSEMBLY?

Thanks in advance

Either the board or capacitor have failed. If the motor is HOT the motor could also be the problem. in oder to tell if it is the board you will have to check to see if there is power coming fromthe board at the place where wires hook up. If power is there then it is either the motor or cap.

3 split units run from one compressor one is not cooling


If there is 3 indoor units from one condensing unit
(6 pipes at outdoor unit) this is classed as a multi unit

All units will run correctly as long as they all require same mode, cooling or heating, if one unit decides to heat it will shut down until master unit decides to heat then it will start, for each unit to individually heat and cool there would have to be 3 pipes to each indoor,

LG split system cooler/ heater heater not working


This could be a problem with the interconnecting wiring or a control board problem with either the indoor or outdoor unit. I would have these issues looked out.

LG split system heater cooler. the heater is not working and fan outside is working


I would check to see if the tech accidently left his jumpers on the unit to keep it running while adding freon. I know it sounds like a simple thing. But all techs have done it at one time or another and that will cause this problem. Due to the fact that you just had freon added there is not a reason anywhere that would cause you no heat unless something was hit when this was being done then something electrical fried

No heat


Please make sure that the correct mode setting has been selected. Depending on model you will see the mode button has four little icons. A star/crystal, a teardrop, a sun (circle with lines out going) and a sort of triangle. You press this button until the correct icon appears on the display, it should be the sun icon.
