Just did the repair on my SWG. Ordered the SL 32 based on the 2010 post that describes the process. When I took out the board (which I had replaced a few years ago) it has the AS 32 thermistor. I read somewhere on Digikey that the AS 32 is being used on the new boards and is stronger but I installed the SL 32 and it worked fine. Digikey didn't have the SL in stock so I had to go to amazon to get it. When I looked up the AS they had a couple of thousand in stock. The AS is $6.53 vs. $2.49 for the SL, so I assume there is some difference. Either way, thank you TFP, you saved me hundreds of dollars and I was up and running in a couple of days.
