Intermatic Timer Trips Manual Override


New member
Sep 17, 2020
I have a Intermatic T104P201 and just recently, when the timer comes around to the ON tripper, it flips the manual override switch to ON, so when the timer comes back around to my OFF tripper, the pump just stays running. I have to remember at night to flip the manual override back to OFF to shut the pump off. Any thoughts on what might be causing this?
