Hello - my pool is running an old dual Intermatic timer (T1202 MT). The right timer is used to operate the booster pump which in turn runs my Polaris cleaner. It will turn off, but never on automatically. I replaced the set tab things and it still won't turn on automatically so I believe the catch mechanism behind the clock is worn out.
I don't want to replace the entire setup of 2 timers. I only want to replace the right side. I could not find a single-only replacement timer for T1202 MT so I bought a T104M hoping I could just swap out the right side (I do know it is 240V going in).
Will I have a problem if I install this T104M in the old right-side timer's place and just ensure all the wires are routed to/from the new timer in exactly the same way?
Old timer (right side to be replaced):
(Yes I know it is old and dirty - I just bought this house and plan to do a full pool remodel when I can afford it after a few higher-priority projects)
