Check your thermostat and mode selector setting, thermostat setting should be set at warmer and mode selector setting should be at low heat or hight this is applicable for manual unit.
If it is a remote control just set the remote to heat mode.

you have lost all control voltage. that is generated in the furnace. either the transformer has failed or the fuse in the transformer board has blown or the circuit breaker to the furnace has tripped or you have an open circuit to the furnace in the high voltage wiring. grab a volt meter and start with checking high volts at the furnace and back to the panel. if you have volts then start checking to see if transformer is generating low volts. as a side, if this is a furnace be sure the door is on secure and the door safty switch is depressed or guess what! no fan no volts no nothing. if any lights on board are flashing etc then you have power and it becomes a control problem. be sure your low voltage is getting sent to the stat via red and common on the furnace terminal board. good luck

You have a safety limit switch that is either bad or needs to be manually reset. Some have little buttons between the two wires going to the switch that you can push to reset. If not they are automatic switchs then one is bad. You have to do an ohms test to see if each switch is bad or good.

there is no reset . some part somewhere has gone bad it had nothing to do with the bad filter ........ troubleshooting a hvac unit is tricky thing to do and if you want someone here to talk you through it , thats just a bad idea . i have spent years learning how to troubleshoot and spent lotts of money on the tools of the trade . i think you should call in a hvac repair person to check out your heater and find out the problem , its money well spent .......if this answer helped please rate this 3 or 4 stars . the high rateing will keep me in the paid answer department thank you

make sure the system switch is in the cool position, then press run program button and allow a couple of minutes for system to cycle on, if it doesn't come on press the button for lowering the set point, set it to 72 degrees and then press the hold temperature key.
