Replacement timer chip for ESB 17 Minute BEEP timer.

CHIP ONLY! NO Timer Included!

Works for 120 Volt / 240 Volt.

*If your ESB 20 minute timer is glitchy, replacing the timer chip may or may not help.

**Timer needs to have a socket for easy installation. Timers without a socket will have to have the chip soldered into the board.
