Will these work for T101M

Will these work for T101M
Asked by: sierra1194
I would think so, I’m using them on the T101. It looks like the T101m might be a new interior mechanism for the timers? It might not be a bad idea to call or email Intermatic.

Rated 3 out of 5 by from on tripper bent I bought 2 sets of the trippers because one of the original "on" trippers bent in such a way as to make it inoperative. I bent it back with pliers to the original conformation and it has been working well since. I bought back up because you never know when you can't repair but must renew. I step back this timer twice since it controls my hot water heater and I think it isn't actually drawing more than 4 hrs per day. therefore, I need to have 4 functioning trippers. that said, I haven't used the replacements yet but feel that they were rather pricey. maybe the digital timer lasts longer and has more control settings but I bought this mechanical one on clearance and felt that it was the best deal I was going to get at the time. also I've had the contacts dirty up on this intermatic timer which only needed to be air blown clean to function again
