I have a 1970 (early) 22 qt pressure canner. The model number is worn off and what I thought it said was M0522 or M0622 is wrong because the replacement gasket is 1/2 inch to big for it. I measured ar

There is a round, rather heavy metal cap sort of thing that fits on the pressure stem and regulates the pressure. Most of the canners have one that can be rotated to different holes for different pressures. You can replace this here

Look under pressure regulators. You might also consider replacing the rubber gasket. Your model number is probably engraved on the bottom of the pan.

Could be just the oil pressure switch is located next to oil filter.

The #7 is a 15 1/2 Qt model and it appears the construction is nearly identical. Hope this helps!

Hi,
Just check and fix below : - Refrigerant pressure ( need to top up if found low pressure) - Wrong set of thermostat ( set it to middle or a bit colder)

You should never go above the 10 lbs pressure during canning. The manual recommends that you prepare the pressure cooker with 1 qt of water and 1 Tbsp of vinegar then set the unit to 5 lbs. Let the unit cool and then repeat at 10 lbs to learn how to maintain the pressure of the pressure cooker. See page 25 (page 24 of the PDF). I found the manual for the Mirro M-0526 here: https://www.appliancefactoryparts.com/pressurecookers/mirro/m-0526.html . The direct link to the manual is https://www.appliancefactoryparts.com/content/pdfs/136681-1.pdf . I also found some Mirro pressure cooker manuals here: http://www.pressurecooker-outlet.com/Pressure-Cooker-Canner-Manuals.htm .

I hope this helps.

I have used a 8 qt. pressure canner (which holds 4 qt) and have done beans and venison. It also holds quarts. I also use an 8 qt. faberware kettle that holds 5 or 6 pint jars with a metal spacer from my pressure canner on the bottom. No problems for 10 years......except my self cleaning oven doesn't work but I don't think that has any thing to do with the canning on top. The bottom of the kettle has to be SMOOTH and FLAT so a regular canner (blue, ribbed bottom) won't work. Burner will come on and off.

You can find one here.
