Here you have some schemes of other models, maybe the voltages are similar, but anyway you could at least see what the LED flashing means:

I have an LG split system air conditioner model number LSZ244VN-4 it is coming up with a fault code of CS after it has been running for approx 5 minutes


There is no CS code. Please read as C5.
Fault Code 05 and 53 (CH05 is displayed at indoor unit, 53 is displayed at outdoor unit)
This fault code indicates a communication error between the indoor and outdoor units; this is usually caused
by wiring errors or condensate pumps connected to the inter-connecting cable.
The communication between the units is a fluctuating DC voltage commonly called a serial signal, it can be
easily lost if the wiring is not done correctly. If there is a communication error fault CH05 will appear within 5
mins of powering up the system.
Testing
• Check Outdoor and Indoor Power Supply Voltages ( 230V ±10% ) and correct as necessary.
• Check for any mis-wiring or loose connections and correct as required.
• Check the resistance between communication line and GND. (Normal: Over 2M).
• If one Indoor unit operates normally Outdoor PCB is generally normal.
Turn on the power and start the indoor unit in cooling, set the temperature to 18ºC; the serial communication
signal will only be present for the first 3 mins of operation.
Set your meter to DC Volts, Test between terminals 5 (Red probe) and 2 or Earth (Black probe) of the outdoor
unit, you should see a fluctuating 0-72 Vdc.
If the Voltage is not present disconnect the terminal 5 cable, test the Voltage between this wire (Red probe)
and 2 or Earth (Black probe), you should see a steady voltage in the range of -0.1 to -10.0 Vdc. If No Voltage
is present either the cable or Indoor PCB must be faulty. This can be determined by checking the voltage
output on the Comms terminal of the Indoor unit, with the Comms wire disconnected. If No Voltage is present
the Indoor PCB must be faulty, if present, cable must be at fault.

I need to know the seer number for an air handler. I'd


On the air handler take the top panel off, look to the left on the inside, this will give you general information on the unit on a stampede plate. This will
give you the date of manufactuer as well.

On the outdoor unit, there is a stamped plate on the
condensing unit. Should have year of manufactuer, it
should also say how many pounds of freon should be
in it. The Model number is what you need to know
to find out how big it is.

024=24,000 BTU= 2ton unit
030=30,000 BTU=2 1/2ton
036=36,000 BTU=3ton
040=40,000BTU= 3 1/2ton
and so on.

My guess is that it is an older unit and since I have
been installling units since 1995 I have only known
any older units to be at least a 10 SEER and no more.

No AC from older Intertherm split system


It sounds like you are low on refridgerant. Double check to make sure both fans and the compressor are running. If so then you have a refridgerant problem.
