Ok, how fussy do you have to be installing those thermistors on the circuit board? Those 020s come with very long legs.
Trim the legs similar to those on the old thermistor. It will dissipate some heat through the legs and into the board, so the board will actually help spread it around a little. Unless you have some desoldering wick or a pump, you can heat the joints and gently rock the leads out one by one. If the board is double sided (can't remember from the pics, but seems like it is) you want to be careful not to pull the plating out that is inside of the hole. With the old one out, put the new one in place and heat joints until you get a nice flow of solder into and through the hole. There's probably some good soldering tutorial videos out there is you need a visual of the process. Just make sure the joints are smooth and shiny...not blobby. I wouldn't do a splice job onto the old leads.
I wonder if they moved the location of the larger thermistor on the new unit because the legs are further apart and wouldn't fit nicely into the old location?
