The Unit won't turn on. I've check all fuses and circuits and there is power to the unit. The thermostat is new, it's a Honeywell T5 and is set for heating. The damper on the unit opens but nothing else happens, no fan, nothing. I set the fan to run mode on the thermostat and the fan did come on. I am not hearing anything coming from the unit. I know this is an older unit but I already replaced on furnace and 3 AC units within the last 7 months. Any suggestions would be greatly appreciated.

If you're not in a climate with real winters, it may be worth fixing but the heat exchanger needs to be checked first.
