Timer

There is a heater we sometimes use that went on the fritz and turned a cold sholder on us. I took it apart and traced the trouble to this timer. For some reason it wouldn't tell the heater to come on when it's time arrived.
The nice thing about working on something that is broken is that you can't make it work any less well than it does when you start--it is already not working. It turned out that the switch inside the timer needed adjustment and all is now warm and cozy.
