Oops sorry about the typo the 2344 Combine Air Screen Monitor keeps going off. We have replaced the sender and checked the side door panel to be sure it is tight.
Might have the technicians check and make sure that the instrument cluster is configured for the correct machine. Due to the hydraulic drive on the 88's with no sensor and the instrument cluster fitting all machines it must be configured properly. Also make sure that the vertical sheet is not being warped causing the seal to drag and stopping the screen. This has been an issue in the past.
Ihad a 1680 that did the same thing for 11 years that I owned it-bought it new. The dealer tried replacing everything one a t a time. It still did it when I sold the machine. I finally learned to ignore it and eventually just disconnected the monitor. The combine never got hot, so I decided there was nothing to worry about.
