That part is probably going bad. The motor uses it to get moving and when it fails then the motor wont start, makes buzzing or humming noise due to phase loss.
Code 41= blower out of valid speed range. you will more than likely need a new motor module. they are not cheap 300$ to 400$. If you call a carrier or bryant tech out they should have a test module they carry on their truck that lets you know if its the furnace circuit board or motor module.
Your fan delay relay is not functioning. On most furnace fan controls, there is a fan delay relay that delay the fan from turning on until it senses the temperature increase, typically around 130 degrees. once the relay senses the temperature increase it closes a contact inside the sensor and turns the blower on. It is the same device that keeps the fan running once the furnace turns off. Just take the Model number and serial number to your local dealer and get a fan delay relay and replace it.
The blue wire from the Ac goes to the y2 on the board for the furnace the yellow and brown goes to c on the board for the furnace and the last wire goes to y1 on the board for the furnace
Your t-stat should be set up so that the furnace is the second stage heat and also emergency heat. First stage (heat Pump comes on) sometimes they use Time to start 2nd stage, sometimes they use outdoor temp and this all bepends how bryant has set it up, without a model # I cannot tell you but send it and i will look in somebooks i have to tell you.
