DoorKing 9000 Slide Gate Operator Parts
DoorKing 9000 Series Slide Gate Operator Replacement Parts
Genuine DoorKing replacement parts for the 9000 series slide gate operator, covering both the 9000-080 (1/2 HP, 115V) and the 9000-085 (1 HP, 115V). The two builds share most of the machine, so they are listed together with a quantity column for each. The reference numbers match the callout numbers on the diagrams — find the number on the drawing, then click the part number in that row.
1/2 HP vs 1 HP — what differs. The motor, gearbox and everything that bolts the gearbox down: motor (9000-156 vs 2601-237), gearbox (2601-235 vs 2601-236), gearbox mounting hardware (3/8-16 on the 1/2 HP, 9/16-12 on the 1 HP), pivot release bracket and its metric bolts, release lever (9000-123 vs 9000-121) and the drive belt (31 in. vs 32 in.). The chassis, limit box, control enclosure and covers are identical. A dash in a quantity column means the part is not used on that build.
Ref 20 — the 1/2 HP motor. The drawing shows 1601-074, which DoorKing no longer lists. The current service part is 9000-156 Motor 1/2 HP Assembly, shown here instead.
Circuit Board — the most replaced part on the 9000
4405-010 — PCB Gate Operator
The same board runs the 9000 series and the 1175, 6500 and 6550 swing gate operators — one board number covers all four, so do not be put off if the product title names a different model. Replace it when the operator is dead with power confirmed at the terminals, when it powers up but ignores every input (radio, keypad, loop, push button), when only one direction works, or after a lightning or surge event.
Check your date of manufacture before you order. DoorKing revised this board in January 2016. The base part number is 4405-010 and the suffix identifies the version:
- -018 — operators built January 2016 or later (current board, UL325 monitored device input)
- -012 — operators built prior to January 2016
You do not order those numbers separately. Open the 4405-010 product page and choose your Date of Manufacture from the dropdown — the two choices read "Unit manufactured before Jan 2016" and "Unit manufactured after Jan 2016 with UL325 monitored device input". If you are unsure, read the number printed on the board currently fitted; it will end in -012 or -018.
On the 1/2 HP build, replace the 4001-093 MOV assembly (ref 239) at the same time. A surge big enough to kill the board almost always takes the varistor with it, and a spent varistor leaves the new board unprotected. Check the 2343-010 current sensor board as well — it sits on the same supply and fails from the same surges.
