    Trouble shooting carrier heat pump
    Ac or heat pump will not come on when I reset the breaker it makes a humming noise about one second and then does nothing. It's a carrier 4 ton unit the unit is 12 years old the breaker does not trip. The fan does not come on either on the outside unit. The air handler is fine.
