I bought a programmable thermostat I misplaced my manual. The fan does not want to turn off and when the heat comes on I have a display that shows a sign of fire and one that shows a music note what does it mean

You need to let all of us know what model and mfg. of thermostat you have. And what type of furnace you have... if the old thermostat worked OK then you either have a wiring issue, or the wrong thermostat.
We are waiting to help you.

I have the similar problem where my fan does not want to switch off. I am working with the customer service to get rid of yhis issue. It sems the thermostat is faulty.
The music & fire symbol indicates that the heat is on.
