Youtube gate specialist broke my module - Harvie C - 12-10-2025
I have a Nice Module 824H system. I purchased four keypads and learned that each channel can handle two pads, so I planned to watch YouTube to figure out the wiring for the remaining channels. While attempting some wiring, I suddenly blew the module fuse, and the system lost power.
After replacing the fuse, the system thankfully came back online, but the indicator lights were flashing differently. I've been studying the programming notes and details but haven't had any luck resolving the issue.
Complicating things further, two red wires became unplugged. I can't recall if they were connected together into the STOP terminal or if they were split, with one going into STOP and the other into the BUS. I initially split them. When I first had both wires connected to STOP, L1 and L2 were blinking. When I split them, L3 and L4 were flashing, in addition to the BUS light. The flashes do not match the fault codes listed; they just flash continuously without any pause.
To make matters worse, a universal module, a LiftMaster LM850, is also attached. I don't know where to go from here. I've tried resets and reprogramming. The relay only clicks when I use the FOB, and although I hear the click, it doesn't activate anything. I'm hoping someone can provide direction on what I should do before hiring a professional.
