Why won't my furnace fan turn on with the heat?
I have a Coleman Evcon electric furnace. This morning, I woke up, and the heat was on, but the fan wasn't. I turned the fan switch to "On," and the fan turned right on. I switched it back to "Auto," and the fan turned off. It turns on normally if I turn on the A/C, but it won't work with the heat. What could be causing it to do that?
I installed a new thermostat, but it didn't fix the problem.

Those units have fuses or breakers so they can be checked and tested.

There is a temperature sensor in the furnace that enables the fan WHEN the heat is hot enough to give comfort. That is where I would start looking for the problem.
