Genuine DoorKing replacement parts for the 6300 swing gate operator, covering both the 6300-080 (1/2 HP, 115V) and the 6300-084 (1 HP, 115V), both Rev K. The two builds share almost every part, 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.
4502-010 — PCB Gate Operator
The same board runs the 6050, 6100 and 6300 swing gate operators. 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 4502-010 and the suffix identifies the version:
You do not order those numbers separately. Open the 4502-010 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.
Replace the 4001-093 MOV / varistor assembly (ref 24) 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.
1/2 HP vs 1 HP — what actually differs. Only six things: the motor (2600-129 vs 2600-162), the run capacitor and its clamp (2600-102 and 2600-875, fitted to the 1/2 HP only), the 2615-870 button socket bolt and the 8-32 hex nut 2620-401 (one on each build), and the quantities of four hardware items. Everything else — housing, clutch, worm gear, shaft, board, cover — is identical. A dash in a quantity column means that part is not used on that build.
