Door Open Function; Prime Button - Yoder Smokers YS640 Operation Manual

Door Open Function

When the cooker has been in maintenance for more than 10 minutes and the cooker loses more than 15
degrees, the program interpretes that the cooking chamber door has been opened. When this happens,
there is a specifi c piece of programming that is executed to speed recovery back to the set point.

Prime Button

The prime button overrides the program altogether and turns the auger continuously, feeding pellets as
long as the button is depressed. This is valuable anytime you have had the door open for a long time and
have lost signifi cant temperature or if you want to raise the cooker temperature from say 250 to 350° F.
To use this function, press and hold the prime button on for 60 seconds, then let off for 60 seconds. You
may repeat this twice allowing at least 2 minutes before repeating.
