Step 1
Realize that a pressure cooker may have one of two styles of gauges: a removable weighted pressure gauge or a fixed dial gauge.
-
Step 2
Understand that weighted pressure gauges do not need to be tested or calibrated. Just keep them clean and free of rust. Dial pressure gauges must be calibrated at least once each year to ensure proper, safe functioning.
-
Step 3
Have your pressure cooker gauge tested either by your local cooperative extension program or send it to the manufacturer to be tested. If your gauge cannot be properly recalibrated, it needs to be replaced.
-
Step 4
Have the manufacturer replace the pressure cooker gauge if they discover that the gauge cannot be recalibrated. This will save you having to return ship the pressure cooker again. If the manufacturer does not provide this service, see Step 5.
-
Step 5
Order a replacement pressure cooker gauge from the retailer where you purchased your pressure cooker, from the manufacturer or from another home food preservation supply source.
-
Step 6
Bring the pressure cooker and the replacement dial gauge to your local cooperative extension office so they can properly install the new gauge for you. There will likely be a small fee for this service. You may have to leave the pressure cooker overnight and pick it up a few days later.
