Arrived at this call for system not cooling, upon arrival was informed by Miss Kimberly that she had a previous company that diagnosed a bad indoor fan delay board timer was bad, informed I’d do my own diagnosis and tested various system components including voltage and blower motor which are present, tested delay timer control board and set it to zero to test functions, found board is receiving 24 volts but the board is not sending 24 volts needed to the blower fan control going to the motor thus the motor is not running, tested motor by sending 24 volts directly to the blower motor and the blower motor came on.
