There is a bimetallic sensor (item # 56854) embedded underneath the pot. It looks like a bottle cap and when water boils off, the temperature increases above the boiling point causing the sensor to “pop.” When this happens, it hits the shut off stem assembly (item # 56857) in the middle of the base of the unit. If you are having one or more of the problems noted above, the distance in between these two parts needs to be adjusted or otherwise corrected.

If the cooker shuts off too soon, do not immediately press the cook button a second time. The sensor has activated and must cool down to be reset. If the cook button is immediately pressed again, the rice will burn.
Verify that the jacket, pot, bimetallic sensor, and shut off stem assembly are all properly mounted and clean. There should be no debris on or around the components and especially on the mating surfaces. Clean, remount and adjust as necessary.
If no issues are found, or issues were corrected and the problem persists, we now need to determine if the bimetallic sensor is operating properly.
If you do not hear both clicks, you will need to replace the bimetallic sensor (item # 56854). If you hear both clicks, the sensor is working properly. We can now try to adjust the distance between the parts.

If you do not hear both clicks, you will need to obtain replacement parts. We recommend obtaining both the bimetallic sensor, and the shut off assembly, and replacing them as necessary. They are relatively inexpensive and can be replaced with basic tools. It’s discussed and shown in our RM series instructional video: RM-55 Overview
