Kelvinator air conditioner error code e6

Kelvinator air conditioner error code e6

This error code indicates a communication fault. Please the DC as follows:

  • Near the isolation switch, turn the power off.
  • Disconnect the Signal Wire off the indoor terminal block.
  • Turn the unit on and let it operate in the standby mode.
  • Test the DC output from the signal wire, which connects to the indoor unit and ground, using a multimeter.
  • If it shows low stable voltage, the indoor PCB is operating properly.
  • Test the output signal on the terminal block of the outdoor unit’s PCB and grounding using the same method.
  • If the voltage is pulsing near the low 50’s, the outdoor PCB is operating properly.
  • If it is 0 DC volts, the PCB is bad.

Using the isolation switch, disconnect the main power supply to the indoor unit. Turn it back on after a minute or so and run the Auto mode. Set the temperature at two degrees above or below the current room air temperature.
