    There is a blower relay that could be the problem ($5.00), the t-stat, or a bad fan motor-either locked-up bearings or burned out windings. You need a meter to check anything except whether the motor is locked-up. To check that turn off power to furnace and see if fan turns freely. If not, replace motor ($40-50). The blower assembly slides out and unplugs. You can slide it out and test it with a meter. DrTom4444
