Just had a board inside the heat pump replaced because it wouldn't turn on in heat mode. It has always worked fine during cooling. The service tech got it working, but when I returned it was extremely hot in the house and the unit would not turn off. I had to turn off the breaker to get it to shut off. Now the unit turns on but there is no air coming out of vents. It's as if the blower is not working now. Any thoughts?
