The error code you are probably getting is "Sht". This means that there is a short in the wiring somewhere. Disconnect the blue wire at the discplay from the wire that connects it to the sensors. This should cause the display to read "OPn" instead of "Sht". If it does that, then there is no issue with the display and it is either the sensors or the wiring that connects the sensors to the display. If the display stays on that short error code, then the display is bad and needs to be replaced.
