Chris M came out due to no heat. Performed diagnostic. Found hot surface igniter has failed. Found that the induction fan motor is failing due to the bearing noises coming from the motor. Took amp draw on induction motor as well. Providing customer with options. Got permission to perform work. Went and grabbed oem hot surface igniter from carrier supply house. Came back with proper component. Took old hot surface igniter out. Installed with new hot surface igniter. Went to test system. Found dirty flame sensor. This was probably the cause of the igniter failure. Cleaned flame sensor. Retested system. Found only one to two of the burners lighting and not functioning all the way. Cleaned burner assembly. Retested system. System is heating and operational at this time according to manufacture specifications. 2 years parts and labor warranty on repair made today. Customer paid in full on cc.
