I have a digital timer that looks like this:
Amazon.com: Intermatic PB313E 24-Hour 16-Amps 120-Volt Electric Timer: Home Improvement
The digital display stopped working today. It appears to be functioning, because pressing the on/off/auto button does turn the pump on or off. And the red power light is on. But nothing is on the display.
Do I just need to replace it? Looks like a fairly cheap part on Amazon?
