I’ve changed all of the ambient temperature sensors, vacuumed the system down then recharged it, also changed out the control panel! For some reason my ambient temperature is showing -50 when it’s 100 outside. I’ve seen where many people’s had the same issue without any answers on how to repair it. Hopefully someone can give answers to this issue.
