Do the indoor and the outdoor fans run when the cooling or heating is on? The compressor? Is there free airflow thru the radiator coils. Indoor and outdoor? Can only guess "fan relay", a fan's work not being sensed. Or a faulty frost/defrost circuit.

Why does my sanyo model KHS2472 has a red light blinking in heat mode and a green in cooling mode, does not work in either mode makes a gurgling sound when it tries to run?

Hi,
The red light indicates it's either heating or in defrost mode
Check the outdoor unit if the compressor is running - the large pipe on the outdoor unit should be hot on heating or cool to touch on cooling
When in heating mode - the indoor fan will not start until the indoor coil is warm enough
If the reversing valve that changes from heating to cooling is faulty then you may encounter the same symptoms too
Probably need a Refrig Tech to have a look at it?
Good luck

Friedrich ductless heat pump will not start up.

Did you check to see if the compressor is running? Check out start relay/capacitor.

I have just purchased and installed a Samsung AQ12FEN. A qualified Airconditioner company installed the unit. The slpit unit installation is a back to back configuration It replaced a 8 year old split...

This could be caused by an installation problem. The system could be severly overcharged, causing the compressor to load up and can cause a failure. i would start there. Is your intaller qualified to install these systems? (does he know what he is doing?)
I recommend, checking the refrigerant pressures first. You can also check the Polarity of the high voltage in to the outdoor unit. If the compressor is an Inverter Drive compressor, and the polarity is reversed, the compressor can run backwards causing the noise and eventual failure. To correct a polarity problem, simply remove the 2 high voltage wires that feed power to the outdoor unit from the board or contactor. Then reconnect those 2 wires, in the opposite position. (say you take loose from the unit and the Black wire is on the right side, and the white wire is on the left side. Simply swap sides, reconnect the Black wire on the left side, and the White wire on the right side.

Hope this helps,
Brian

When calling for heat the outdoor unit fan cuts off and the compressor stays running after about forty seconds.

Actually, for heating mode, the condenser fan works on pressure build up by Fan pressure Switch. If pressure less the fan won't run.

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.

Sounds like your aircon is stuck on heating mode. Or. The outdoor fan speed is affected by ambient temperature, or low refrigerant. In heating mode the indoor fan will come on for a while to sense temperature and will then wait for the outdoor unit to pump up pressure and build up heat.
