I'm getting power to the controler but unit won't turn on. Micro switches are working and no led lights on buttons light up.

Here is your tech sheet

I assume you checked for 120 volts from P4 to P6 and P8 on the control board, and it is OK.
If not it might be the Non-Resettable Bi-Metal (thermal fuse) is blown.

Without a keypad response you will not be able to run diagnostics, so it becomes a crap shoot.
Remove the door's inner cover and look on the board for any obvious blown components.

Try the below
RIBBON CABLE CLEANING
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.

on thecontrol board, you will see a small round part, the size of a dime, and 2 wires coming to it. that is a thermal fuse. that could cut the power to the board. i would make sure you have the power off, and then take the 2 wires off of it, and then put them together, and then put a little tape around the 2 wires so they do not hit metal, and then put it back together, and turn the power on and see if it works. if it does not work, order a new control board, and the fuse. the fuse does not come with the new board. tom
