If E1 fault has not cleared:
# Check the continuity of the wire that connects to the reactor (R1502) spade terminal located to the rear
of the outdoor unit, too the two terminal relay located under the main outdoor PCB.
Note:
Check the continuity of the reactor. If it’s open circuit, this will also cause an E1 fault.
#
If there is a open circuit in any of the (R1502) reactor connection points, check the two point plug
located on the harness which runs between the main outdoor PCB & the (R1502) reactor.
Rear terminal point.
