Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

These are NLA, but you can try unplugging the cable to the remote receiver and the control box and see if that corrects this. Parts are really hard to find and you may have to upgrade to a newer thermostat and control. Let me know if you need to pursue this and I can direct you further.
