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,

Indoor fan slow to rotate in heat mode and no heat/compressor


The indoor fan will not run at normal fan speed untill the indoor coil reaches 32oC. This is done so that a cold draught is not felt when outdoor unit is not running. Check to make sure the outdoor unit is operating. If the outdoor fan is running but there is no indoor fan after 5 mins then you must likely have a gas issue or a fault compressor circuit.

Split unit, I get heat but no cold


I have run into this with the LG brand systems. try shutting power off to the outdoor unit to reset all units. If problem persists, it could have to do with a charge level of refrigerant (freon) or possibly a failed control board.

Will Not Heat


On the outdoor unit the fan should not be running, on the indoor unit the fan should be running. If you then check the outdoor unit with fan not running, you should be able to hear clearly that the compressor is actually working. If this is all correct, it is possible that your fourway reverse valve is seeping and needs to be replaced.
