MT14A controller acting.....irrational

[nabril15]

Good morning to all
My trusted and reliable MT14A little box works well I shall say, 95% of the time, with a sliding scale...
At times, things come on that shouldn't, but I've learned to accept it.

When I go to the timer to look at what's programmed and to correct one of those phantom turn-on's, I get more irrational behavior.
With the slider button on PROG, I will, for example, press the 4 button ON to see that time(s) are programmed.
As I press that ON button for 4, the display will show me the times for other number codes. So pressing 4 ON, I'll see:
4 09:15AM
8 07:00 PM
6 05:30 PM
etc

That happens with the number 4 code or any other, and I make sure to keep the 1-4 or 5-8 button on the right position for the number code that I'm checking.

Could this be causing the random on's
Is it time to replace my timer? Is there a way to reset it kind of thing?

Thank you

First thing I would do is operate those sliders back and forth a few times to see if that helps by removing oxidation.  Those sliders have contacts that bridge copper traces on the circuit board which can oxidize or wear out.  Cleaning can help but if worn out just replace.

Thanks Brobin
The slider for 1-4 or 5-8 slides waaaaay too easily.
If I tilt the timer, that slider usually moves.

In that case you can open the unit and it'll be obvious as to how to bend the contacts attached to the buttons to correct that.
I PM'd you with another suggestion and a link to it.

I took it apart and the 2 left screw pegs where the top board arraches, were broken off. And the 1-4 slider button had the top and bottom plastic resistance pieces broken off.

It's time to replace the timer.
