I have an LG inverter V that the cooling light is blinking 5 times. I have turned the breaker off and back on. My A/C guy doesn't know anything

SOURCE: sony sxrd 60 in, won't power up--blinking red light 5 times

You need to replace your bulb. Order a replacement online---it's easy to swap and the instructions are in your manual. If you purchase one from a local dealer you will pay over $150 more!!!

We have the same problem as of this morning . . . don't have the fix yet, but have located (2) manuals that I will enclose the links for. The 5 flashing green lights is mentioned in the "Service Manual" in Section 2 "Troubleshooting" with 5 possible remedies. Manual http://www.transportaircon.carrier.com/Files/Bus/Local/US-en/T298.pdf and Parts List http://www.transportaircon.carrier.com/Files/Bus/Local/US-en/T298PL.pdf We're under warranty so will take our RV in ASAP

SOURCE: Carrier A/C in RV won't run

check your breakers make sure when running unit this is the only thing on the breaker 15 to 20 amp be sure to keep a window cracked as well unit does freeze over so don't have all the way on cold

Fault Code 05.
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. Helpful?

If it s a 230v5 unit switch the power legs for the air handler unit. If that does not work, make sure the comm wires are 18gauge shielded cable.
