We got a carrier 58wav upflow, an blower quit. Can I test motor? Or just replace?

If the blower does not run normally when thermostat is set to heat, will it run when thermostat fan switch is set to on? Look for status LED behind clear viewer, near blower area. Blinking indicates trouble, observe and note pattern (if any). Check this with thermostat set to demand heating. Check panels for service legend with codes.
