I recently obtained my HVAC technician license and am in the early stages of my career in the industry. Today, I was troubleshooting a 3-ton Goodman 14 SEER packaged residential unit in response to a service call regarding short heating cycles. As part of my diagnostic process, I checked the air filter, inspected the vents and drains for blockages, and assessed the blower motor. I observed that the blower motor starts briefly but then shuts down. Given these symptoms—along with the error code displayed on the LED indicator—a faulty pressure switch appears to be the most likely cause. However, I want to ensure I’m not overlooking any other potential issues. I’d appreciate any guidance or alternative perspectives. Thank you for your time and assistance.
