wow, i think carol may be right; it sounds like u may need to retire that thing. u should consider this one:
Hamilton Beach 33134 3-in-1 Slow Cooker with 2-, 4-, and 6-Quart Crocks
it's really inspired me to start cooking with the slow cooker. it's nice having the options of different size crocks, depending on the recipe. and an added bonus, aesthetically it's beautiful. the crocks come in earth tone shades of yellow, green, and red. food for thought.
