If you have a newer model, you can usually find your model number
on the bottom of the pressure cooker or canner body. If it's a very
old model, the number can probably be found on a label attached to
the top of the cover. Old units have model numbers like 40, 50, 204,
603, etc. Newer models usually start with 01/ or 02/ followed by
letters like PA or PC and more letters and/or numbers. The most recent
styles always have seven digit ( all numerical) model numbers starting
with 01 or 02 (Example: 0136001).
Note: All Presto Pressure Cookers and Canners
also have the number "409A" stamped
on the bottom. This is not the model number! It is a number used
to indicate the product's listing by Underwriters Laboratories
(UL). Do not enter this number. Continue to look for a number
more like
the ones described above.
