emm... not heat
The standard Suburban furnace that well, almost everyone has. Worked fine all week, we stopped for lunch on the way home, since it was cold I went to turn the heat on for the critters, only no joy....

If furnace fan is not coming on.........all the propane in the world won't help.
The fan gets power from DC Dist panel (fuse).
DC power is on control board blower circuit (use to be on a timed delay relay).
When the t-stat clicks it sends DC power to the control board which allows DC power to go to motor. Fan runs purging combustion chamber, makes up sail switch/limit switch which allows DC power back to board. Board then sends DC power to gas valve and spark electrode for ignition. Main flame light off, flame is proved......heat. Temp set point of t-stat is reached....t-stat opens and drops power off timer circuit on board......which then allows fan to run for cool down cycle until timed out.
You hear click at t-stat.
You hear click at furnace (timer on control board)
But no fan (motor doesn't start).
Bad blower circuit on control board (unless you have a separate timed delay relay....but it being a 2012 model probably on the control board) OR bad motor
Do you have a furnace with outside access cover or only from inside?
You can check for DC power at power terminal on board and then to motor (red wire).
Power to board and not to motor.....bad board
Power to board and to motor......bad motor
Provided you have good ground circuit.
If bad board..replace with one from Dinosaur Boards...Fan 50 Plus style
And provided you have good DC voltage.
