Diagnosis of a 17 year old carrier split system, for no air flow. Found outside unit operational. The indoor blower motor was not operational. I checked the run cap and found it reading 0 mfd when rated for 7.5mfd. Recommended changing cap. Homeowner agreed to changing the cap. The blower motor was hot to the touch. And not starting after installing new run cap. Let motor cool down to see if it was thermally locked out. After cool down the motor still did not operate. I recommend replacing motor and speaking with a comfort advisor for replacement options.
