I saved an old favorite battery powered beard trimmer by having new batteries installed by them. I tried but solder wouldn't stick to the stainless steel contacts that were part of a PC board.

Radio Shack sells thermal fuses, such as this one:

which looks like an ideal replacement for a coffee maker. I have used these in the past, with great success.

But, how did they solder the stainless steel contacts to the PCB? But seriously,a few taps with a Dremel equipped with a small abrasive disc will remove the plating/corrosion/oxidation that might be on the contacts, revealing a nice, solderable surface undeneath.
