Liftmaster CAPAC Access Control Parts
LiftMaster CAPAC Replacement Parts
Genuine LiftMaster replacement parts for the CAPAC Smart Access Hub — the myQ-connected controller that brings a gate operator or access system online over cellular, Wi-Fi or Ethernet, with two relay outputs, two Wiegand inputs and two general inputs. Use the diagram above to find the key number for the part you need, then click any part number in the tables below.
The hub takes two antennas. K41-0231-000 is sold individually, so order a quantity of 2 to replace both.
Poor cellular signal? Where the hub sits inside a metal cabinet, below grade or anywhere reception is marginal, the CELLXKT external antenna kit moves the antenna clear of the enclosure. That is usually a better fix than replacing the standard antennas.
Power is a plug-in supply. The 041D0270 feeds the hub's POWER terminal, which accepts 12–24V. Check the outlet and the lead before ordering a replacement.
