clock motor is on back.

Check general condition of gears.
Apply bit of white grease to steel gears.
Clock motor gears are plastic so they will not bind against steel gears.
If clock motor gear is stripped out where it meets steel gear, then the steel gears might have debris that is binding gears to a halt. Clean steel gears.




Look for model number.
Clock motors start with WG or CW etc

WG series clock motor

How to troubleshoot Intermatic timer


water heater element

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.

Sprinkler timers

When planning watering times it is important to understand how the timer works. The timer just turns on-and-off, and each time the timer turns off, the sprinkler valve automatically advances to next zone. So the sprinkler valve is doing the mechanical job of advancing through each zone.

Rain sensor is not supplied with timer. Buy separate rain sensor. The rain sensor plugs into standard outlet. Connect the wires from rain sensor to terminals on timer. Do not apply voltage to rain sensor terminals.

T8845PV has 24Volt transformer with two yellow wires. Connect yellow wires to sprinkler solinoid. Connect 120Volt power to terminals marked Line and Neutral. Line is the black hot wire. Neutral is the white wire. Do not connect power to yellow wires.

All brands of timers including Intermatic sprinkler:
With 120Volts, Line is the black hot wire. And Neutral is the white wire. Connect the black and white wires to terminals marked Line and Neutral.
With 240Volts, both wires from breaker are hot Line wires. L1 and L2. Either hot wire can connect to either terminal without regard to wire color.
