DoorKing 9100 Slide Gate Operator Parts
DoorKing 9100 Slide Gate Operator Replacement Parts
Genuine DoorKing replacement parts for the 9100 slide gate operator (model 9100-080, 1/2 HP 115V, drawing 9100-880 Rev I). 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 9100 is the same chassis as the DoorKing 9050 and the 9070 — housing 2600-985, door 2600-933, motor 2600-129, clutch pad 2600-342, belt 2600-429, pulley 2600-957, main shaft 2600-903 and bearing kit 2600-466 are all shared. What is specific to the 9100: the 4602-010 control board (the 9050 uses 4702-010), the 9100-006 plastic cover, the 2901-002 18-pin terminal (the 9050 uses a 12-pin 2600-826), the 2600-988 wire set, and two 2600-848 power resistors. If a part is not listed here, check the 9050 page.
Circuit Board — the most replaced part on the 9100
4602-010 — PCB Slide Gate Operator
The 4602-010 runs the 9100 and the 9150. It is not the board used by the 9050 or 9070 — those take the 4702-010, and the two are not interchangeable even though the operators share a housing. Check the model on your cabinet label before ordering. Replace the board 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 4602-010 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 4602-010 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.
Check the two 2600-848 power resistors and the 2901-002 18-pin terminal while the board is out. Both sit in the same circuit, both take the same surge, and a scorched terminal will cook a new board within weeks.
