While the AC is working some of the electronic switches don’t seem to be working ( see pics ) . Is there a way to test them? or where can they be purchased I feel they must be a pretty cheep item. Also what exactly are they called?? Thanks

Update (09/04/2018) Hope these pics help. If I put the leads on right two contacts it could be open or closed. When I work the switch that should change to the opposite of what it was ??

@mattwasho those are micro switches. You can test them by connecting the black and red leads from a multimeter to the contacts on either side of the switch. (If you can post a better /clearere picture from both side of the board we can show you where the contacts are precisely.) Use an analog meter, set your multimeter to something like OhmX1K. When the contact closes an analog meters needle will move to the other end of the scale. That shows the switch is closed. The reverse is tru for an open switch.. The needle will move to 0 on the scale. Update (09/06/2018)
I’ve marked a couple of the switches on the backside of your through-the-hole circuit board. Each switch has two contacts. set your meter to the before mentioned ohm scale and touch teh two contacts. Needle moves teh witch is closed, push to open needle should go back to zero. If it is a normally open switch then the needle will be at 0 until you push the sitch to close the circuit. the needle will then move. Either way, if the needle of an analog meter moves while activationg the switch, it is working. You can test all of your switches that way.
