Thank you Micabay and Samurai.
I didn't try jumpering the noise filter because I was afraid of damaging the PCB if it wasn't already damaged. I guess now I don't need to worry about that. I will give it a try. I'm wondering about the switches or whatever these things are called (photos below). I haven't figured out which are NO and which are NC, but only some of them register Ohms with my multimeter. The heater is one of those that does not.
Do these have little fuses inside of them? If they are NC, then I would assume they would show continuity when the machine is off. I don't know how to close those that are NO. Pushing buttons does nothing since the machine won't turn on. I know I'm out of my league here, but last time I tried to have a repair man out, it was a disaster. He had no idea what to do, so I figured I have no idea what to do either, but I don't charge $150 to not know.
I'm looking for someone to come out now, but will keep trying to fix it myself now.
Thank you for your help. I'm going to investigate those "switches" and see if that's where the problem could lie.
if this doesn't work, you can see the photos here: https://drive.google...QWM&usp=sharing
