Problems with Intermatic timers are caused by defective trippers, incorrect wiring, tripped circuit breakers, a faulty time clock motor and incorrectly set power terminals. Other causes include rusted springs, insect infestation and loose timer dogs.Continue Reading
A loose tripper can cause failure of the Intermatic timer to turn on or off automatically at the set times. Additionally, a faulty tab can cause failure of the timer to turn on or off when the dial is rotating. Poor wiring in the load can hinder the timer from keeping time when the load turns on using the manual lever. Additionally, a loose wire can cause failure of the load to turn on or off when the dial rotates on time.
A tripped circuit breaker or a defective supply cable can cause power supply deficiency in the timer. A defective time clock motor can cause failure of the timer to keep time, when there is incoming power in the electric cable. An error in the power terminal connections can cause the timer and the clock to shut down simultaneously when the timer reaches the shutoff time.
A defective time clock motor causes the load to turn on or off with override, but not at the scheduled time. A rusted small spring behind the screw or a loose screw can cause the timer's pointer to be loose. Insect infestation at the contacts behind the timer's clock can make it hard to flip the timer's manual level.Learn more about Time & Calendars
