Hello ,
I have a magic chef furnace that was working and all of a sudden quit. I am getting power to the furnace, and motor is good because I removed motor and had it professionally tested. I was not getting power to blower motor but could hear the click from the relay, I tried both heat and cool and both auto and on and still no blower.by this description alone does it sound like a common problem?

I would test voltage, and verify power to motor, if none, check in and out of relay.
Motor could have went bad on the way home, or they meant to test it.
The relay is working off 24 volt transformer and thermostat. They sound OK.
Because a relay clicks, does not mean it is OK. Good Luck
