Disconnect the main power supply to the outdoor unit by means of the isolation switch. After
approximately one minute, turn the power supply back on & attempt to operate the unit on heating or
cooling mode by the use of the remote control.
If E1 fault has not cleared:
# Check the continuity of the (3uF) indoor fan capacitor mounted vertically inside the indoor control box
assembly.
# Measure the resistance of the Blue & Black wires that connect from the 3uF capacitor to the indoor fan
motor. The resistance reading should be approximately “322 Ohms”, at an ambient temperature of 22ºC.
