There is no reset button
When you program it will the time display count down ?
ok then you have a bad control .
If the light comes on and if it does not count down when you program a cycle .
Here is a link to the part .
it is mounted in the console.
Do you have a Volt-Ohm meter to do some voltage tests?
ok But it will still be the main control , if the issues you are having is what you provided me .
but I will be on line every evening
