Troubleshoot Household timers

9) Troubleshoot
Some timers have reset button letting you revive old timer that stopped working.
Some timers will not display if timer wired incorrectly.
Some timers have rechargeable battery that must be charged 1 hour before programming.
Rechargeable batteries wear out and timer goes bad.
Some timers have battery that needs replacement.
Timers with battery will stop displaying if exposed to cold temperatures over several days.
Random vacation timers cannot be programmed > they have internal preset times for on-off operation.
10) Confused about setting analog dial timer with segments or pins?
How these timers work:
Clock motor inside timer rotates the dial as time passes, and the segments-or-pins click a tiny switch that turns lights on-off.
1) Locate segments or pins on outer edge of dial, and move some segments up and leave others down. Or move pins in or out.
2) Turn lamp on, plug lamp into timer, plug timer into wall.
3) Manually rotate timer dial clockwise and watch Load (lamp, light, motor) turn on-off.
4) Most timers also have override switch, so move switch both directions to see how timer reacts while rotating the dial..
5) Manually rotating timer dial will show you how to set segments-pins and switch
6) Look at numbers printed on the dial. Each number represents time on a clock.
Some timers are 24 hour and some are 7-day.
7) The analog dial can have dark and light backgrounds that correspond to day and night.
Numbers with dark background are for nighttime hours.
8) Set segments-pins to turn on-off at hours you choose.
9) Set current time, rotate dial until current time lines up with arrowhead located on inner dial:
If plug-in timer doesn't work
a) Check receptacle for power
b) Check lamp is turned ON
c) Check bulb is good.
d) Digital programmable: Reset or clear timer before starting
e) Analog: Check tabs or pins are set
f) Check override switch pushed fully in position

g) Try timer in different plug and with different lamp
h) Test circuit with inexpensive circuit analyzer from hardware
i) Don't exceed maximum wattage
j) Digital programmable: check for overlapping programs
k) Digital programmable: write out programming steps
l) Outdoor with photo cell > test with black tape over photo eye
m Always reset digital timer before programming
n) Write out programming steps
o) Turn photo eye away from light source
p) Check if timer has battery

Timers fail frequently?

 More than one timer has same problem? Test outlet.
Outlet polarity Test outlet with circuit analyzer from hardware
Read circuit analyzer
Circuit analyzers at Amazon

Never assume power is OFF

Use non-contact voltage tester on timer, on wire, on outlet to see if power is present.
Press button on tester, if single beep then no power is present. If continuous beep then power is present.
Never stand on bare ground, always stand on dry boards, do not hold or touch anything metal when working on timer or water heater that has power, tape tester leads to wood sticks, never touch wet water heater, or flooded water heater, or timer that had a short or fire without turning power OFF.
