My bad - forgot to unplug after round 3 of disassembly when I replaced door-latch/switch assembly and managed to short it out with a screwdriver. After I reset the breaker, looked inside for blackened contacts - saw nothing, and confirmed there is still power to the door switch (continuity check with all leads removed, put together with back two wires (direct from power cable) and plugged in to check - have switched 117 VAC at this point. Otherwise, dead as a doornail. One nearby device is the actuator for the air vent - that's a wax motor (154226701) that reads open circuit whether it's extended or pressed down. The soap dispenser actuator is also a wax motor (not listed in Frigidaire's parts list, but your site lists the whole dispenser assembly as 154542104 Part Details - FRIGIDAIRE Dispenser, part number: 154542104. This dispenser's wax motor also snaps out and the end doesn't seem to move at all, also reads open circuit.

Can either or both of these result in no power to the timer, etc. or is there something else I need to be looking for? (drain switch, motor connections, etc?) The wiring diagram seems to have large gaps, or else I'm missing something. Is there maybe a breaker that they forgot to mention?

Maybe my message was too long: this is what I meant by "... have switched 117 VAC..."

If I pull off the lugs to the nearer terminals on the door switch and put the meter on them, they are off with the door open and hot when it's closed, as it's supposed to do.

Whatever else is wrong, it's not the door switch and probably not the timer (bought a replacement and triedt it out today - no change.)

I would pull power and check continuity for both door switches. If ok I would check the white power ground connections. Also, pull the cover off the power connections box and check across the white and black wires.

If I may, I would start at the very begining here, start with the basics. If you are not getting any response from the machine, check wall outlet for 120. next go to the junction box, measure black to ground, should have 120v, measure white to ground should read 0volts, measure black to white should be 120v. Do the same for the door switches, black to ground 120v white to ground 0volts. Looking at the wiring diagram, and the previous posts, I suspect you have a neutral wire not connected somewhere, or broken.

You asked for help and we are trying, continuity tests tell me nothing, I need voltage readings at certain spots....Forget your wax motors, those are NOT your problem. You need to find out where you lost power, and I believe we are trying to help you, and FYI it is more difficult than you may think to diagnose things over a forum. If you want to keep thinking those WAX motors are your problem, replace them and find out. If you want your dishwasher fixed, we need to rule out somethings to go forward. You came on here looking for help, we did'nt come to you.
