How can I identify the specs of the transformer on the garage door control board in these pictures, so that I can purchase a replacement?
**broken link removed**
The transformer is labelled "PCX-1635-AUN W2107", roughly 33x41x25mm (d,w,h) and has 7 solder joints on the board.
As a result of sustained overvoltage throughout my house (I measured 150VAC, caused by disconnected neutral due to damaged main line from road), quite a few appliances and electronics were fried. After power company fixed the main line, I fixed the dishwasher board (blown MOV and trace), and next on my list is to fix my garage door openers (Linear LS050). As you can see in the pictures from the charred area, an MOV (labelled RV1) between nuetral and hot blew (I removed it). I plugged the board back in and I see the 120VAC on the primary side of the transformer, but get nothing on the secondaries, so I assume the transformer blew too. The resistor R23 which feeds the transformer looks discolored and the area on the board around it looks like it got really hot, so thinking I should replace it too, though I measured it at 40 ohms. I'm hoping replacing the transformer will fix the board, but I guess something downstream may have already been fried also -- wish I had an idea of what the odds were, but willing to try if there is a chance (to satisfy my DIYer urge and feel like my Electrical Engineering degree isn't going to waste).
