Call is no heat on a carrier infinity communicating heat pump. Diag code on indoor board is a 44 (motor communication fault) typical with bad module. Line voltage and communication harness both getting signal with no response from blower. Module for sure needs replaced. The motor will likely work but would suggest replacing it due to age and price difference. Estimates has been written up and will be included. The module at $1300 and the module and the motor both for $1500
