My intertherm furnace blower stops coming on. If I turn the thermostat up and down several times it will work properly for about a day. then will start doing it again. I have replaced the thermostat and that didn't help

Turn the power off to the unit and use a different color thermostat wire in place of the green wire. If this works, there is a short in the wire. If not it's likely either a relay or a bad motor.
