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.
"CN1" soldered connection point on outdoor
PCB.
Orange connecting wire from (R1815E) reactor.
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.
