Stage 2 with excessive pressure differentials is primarily caused by a failed blowdown valve. The above displays indicate that the computer has found operating conditions outside the normal limits. For most of these displays, you only need to press ENTER to reset the control. If the pressure or temperature is still outside the limits, pressing ENTER will not reset the control. The corrective action for these messages is to find the cause of the indicated problem. Your service representative can provide the service needed to correct these problems.
