Abstract
Systems, methods, and computer program products are disclosed for controlling a fryer having a high limit module. The high limit module selectively decouples a heater of the fryer from an energy source in response to a signal received from a high limit temperature probe indicating a maximum allowable temperature has been exceeded at a hard trip condition. A controller monitors signals received from an operational temperature probe and the high limit temperature probe. Based on these signals, the controller determines if the high limit module is approaching the hard trip condition. If the controller determines the high limit module is approaching the hard trip condition, it preemptively adjusts the output of the heater to avoid the hard trip condition. The controller may thereby prevent the fryer from being completely deactivated by the high limit module.
