GL235 Solar Controller Not Shutting Off Actuator in Auto Mode

Thanks in advance for any assistance:

Using ON and OFF the actuator works fine. Assuming the problem is with the solar sensor. Following the manual's troubleshooting guide I disconnected the sensor and the HEATING light went off correctly and turned back on when I reconnected. My concern is that the CHECK SENSOR light never came on at all with the sensor disconnected. Should I try a new sensor or does it sound like a board issue?
