How do I get a stuck lid off a mirro canner? - Miscellaneous

SOURCE: i have a mirro matic pressure canner model 0406

I too have a Mirro 0406 that my mother gave me some 25 years ago. I LOVE it and use it every year! Fortunately, she gave me the manual along with the canner. It states"When correct pressure is reached, control will jiggle and sputter. To reach the first jiggle in a small cooker may take less than 5 min, or less than 10 min, when canning. Large canner may take 45 to 60 minutes for the first jiggle when canning a full load. Count time from first jiggle and reduce heat so control jiggle about 1 to 4 times a minute for cooking (about 4 jiggles per minute when canning). Constant jiggling causes excessive loss of moisture: the occasional jiggle and a hissing sound indicates pressure is being maintained. (I just canned 14 quarts of green beans with my Mirro today 7/26/09 :) Congradulations on your Mirro canner, I hope you have many years of success with it. Good Luck, and Happy Canning!
