Caution:
Discharge the 50uf capacitor prior to any service work.
If E1 fault has not cleared:
# Check the continuity of the orange connection wire located on the left hand terminal of (R1815E)
reactor to the “CN1” soldered wiring point on the outdoor main PCB.
Note:
Check the continuity of the reactor. If it’s open circuit, this will also cause an E1 fault.
If E1 fault has not cleared:
# Check the continuity of the wire that connects to the reactor (R1502) spade terminal located closest to
the front of the outdoor unit, too the “N-B” soldered connection point on the main outdoor PCB.
