My furnace won't go on when adjusting thermostat to increase…

Customer Question
My furnace won't go...

My furnace won't go on when adjusting thermostat to increase temp

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

Probably has to do with thermostat control as it seems to be working

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

If I know how to adjust temp and know if I am doing it properly, need help with setting it propwrly, it's freezing in here now!!

Contractor's Assistant: Anything else we should know to help you best?

Not that I know of, just want to see if thermostat control is the problem or not
