Riley Plumbing & Heating diagnosed this furnace in 96120 after the homeowner reported smoke and overheating during operation. Our tech found the burners firing correctly, with good blue flame pattern visible. The issue traced back to a blower motor problem, causing heat to build up in the cabinet instead of circulating through the home. Cleared the fault, tested all safety controls, and verified proper airflow. Furnaces that run hot can damage heat exchangers, so catching these problems early matters. Book your heating inspection before small issues become expensive repairs.
