1-channel FMD Intermatic timer

FMD timers are complex to program, and if timer does not program correctly, then check voltage and polarity of circuit. These timers typically have 1 year limited warranty and can be affected by power surge.
If you have 2-channel timer, then each contact on relay will turn on-and-off at different schedules.
Make sure you don't wire both legs of a 240Volt circuit to to different relays, or the circuit will not turn on-off as expected. To control 240V, just turn off one leg using one of the relays.

If your exact timer does not show, add a comment and describe everything about the timer buttons and appearance, and I will search my files for possible manual.
Grasslin timers were made by GE for many years, and now Intermatic owns the product line.

Digi 20E-120 is 16Amp 120Volt flush mount digital timer with 20 or 140 programs per week.
Grasslin Digi (digi tal/ digital) can be reset using reset button.
Reset might restore functionality, but will delete all programming.

Check that circuit is delivering 120Volt and that circuit is clean without interference.

Also check electrical terminals fit tight on the timer.
Use needle nose pliers and pull terminals off and then push back.
The digi series has 5-day program back-up capacitor so programs should remain, but capacitors go bad.
Power surge can blow out timers. Use surge protection on all circuits.

There are a many Digi timers from years of manufacture by GE and now Intermatic, since Intermatic bought Grasslin from GE.
The digi can be replaced with simple-to--program FM1D digital timer.

Replacement crossover is FM1D20E-120

Grasslin qe1 and qe2 manual does not show troubleshoot section.

1) Remove power to unit and see if it will reset.
2) Press reset and hold button longer
3) Manual says: SLIDE SWITCH MUST ALWAYS BE LEFT IN "RUN PRESET PROGRAMME" OR, "RUN OWN PROGRAMME" POSITION, OTHERWISE THE CLOCK WILL NOT RUN, AND NO SWITCHING WILL OCCUR.
4) Timer has stopped working. I test timers, and they all stop working one day.

There are several programmable timers on the market.
Intermatic EJ500 is simple to install and program. Works on battery but is for incandescent light only, not for fans.

GE 15071 from Home Deport is inexpensive replacement and works with fans, lights.
Needs no battery. Uses electric circuit to operate clock.
