The message. Solar sensor open is on the screen and the light is a solid red. Do I need to change a sensor or something. New to the group! Thank you !

Looking at some past posts it appears this is generally related to a broken wire to the solar temp sensor.
To test, you can disconnect the solar temp sensor and temporarily replace with a 10k ohm resister or get a new temp sensor and connect straight to the board. If it clears the error you can replace the sensor on the roof, if the error comes back you know it's the wire.

You can also read the resistance across the two (disconnected wires). It should read high, but not closed circuit or open circuit.
Solar sensor is on the roof. As has been said, check the wiring to it. Depending on how far away the roof is from the equipment there could be a splice that has come loose. The longest wire that comes attached to a sensor that I have seen is 25,' that is seldom enough to reach the roof.
