Thermostats are calling for heat, filters are clean

Contractor's Assistant: Do you plan on doing the work yourself?

Maybe

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

If your unit is in WWSD now as cold as it is then the sensor has probably failed. You can get it back up and running by disconnecting the outdoor sensor from the ODS terminals. Those terminals are on the low voltage terminals strip the same strip the thermostat is connected to.
