DoorKing 9050 Slide Gate Operator Parts
DoorKing 9050 Slide Gate Operator Replacement Parts
Genuine DoorKing replacement parts for the 9050 slide gate operator (model 9050-080, 1/2 HP 115V, drawing 9050-880 Rev K). The reference numbers in the tables below match the callout numbers on each diagram, so find the number on the drawing first, then click the part number in the matching row to go straight to that product page.
The 9050 shares its housing and door with the DoorKing 9100 and the 9070 — part numbers 2600-985 and 2600-933 cover all three. The 4702-010 control board and the 2600-989 wire set are shared with the 9070. If a part is not listed here, check the 9100 page.
Circuit Board — the most replaced part on the 9050
4702-010 — PCB Slide Gate Operator
The 4702-010 runs the 9050 and the 9070. It is not the same board as the 9100 and 9150 (those use the 4602-010), so check the model on your cabinet label before ordering. 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 4702-010 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 4702-010 product page and choose your Date of Manufacture from the dropdown — one choice covers units built before January 2016, the other covers units built after, with the UL325 monitored device input. If you are unsure, read the number printed on the board currently fitted; it will end in -012 or -018.
Replace the 4001-093 MOV assembly (ref 6) 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 2600-826 12-pin terminal for heat damage while the board is out.
