If the machine is not heating (does the top feel warm at all?) then it's likely that you've either tripped the fusible link (protects against overheating), one of your thermostats is faulty or your heating element has ruptured and failed. You can check all of these with a voltmeter, but you'll need to take the top of the machine off first. Make sure the machine is unplugged, then check for continuity across each of aforementioned parts; they should all be closed. If any of them are open, or have no continuity, then that's your faulty part.
