Genuine LiftMaster / Elite 041B0773-1 LED board (also 41B773-1) — the board behind the keypad that lights the keys on the EL2000 and EL2000SS telephone entry systems. A keypad that works but is not lit at night is this board. The same part is also listed on our EL2000 parts page as the 2B721 LED assembly; the EL25 uses the 041B0773 LED kit.
Read the number on the board you are removing. The EL2000, EL2000SS and EL25 share most of their electronics, but each board does one job. The table below says which is which; the main board 041B0735 is discontinued, so if that is the one that has failed, call us before ordering anything else.

Is the board actually the problem?
The EL2000 is a multi-board unit, and the wrong board gets ordered often. Work down this list before you buy:
| Symptom | Check first |
|---|---|
| Unit dead, no display | The transformer and the fuse first; then the main board — which is no longer available, so call us before ordering anything |
| Keys unresponsive or intermittent | The keypad and its ribbon, then the input board |
| Valid code entered, gate relay never fires | The input board, then the output board |
| No audio, or the visitor cannot be heard | The output board and the speaker / microphone |
| Call button does nothing | The call button and the interconnect cables and board |
| Display dark, unit otherwise works | The display cables kit, then the display assembly |
| Keypad not lit | The LED board |
| Unit unresponsive, boards look healthy | The bypass board (SN1600341-K) |
After fitting
Re-test the keypad, the call button, both audio directions and the gate relay before closing the door of the unit.
