# Service Report Responded to return visit for furnace intermittent operation issue where unit would reach setpoint but fail to restart on subsequent heating cycles. Upon inspection, discovered extensive frost and ice buildup throughout the air handler interior, covering coil assembly, metal panels, and interior surfaces. The frost accumulation on evaporator coil and housing components indicates restricted airflow causing the system to freeze during operation, which would result in the observed symptom of unit failure to restart after initial cycling. Documented conditions with photographic evidence showing crystalline frost formation on all interior surfaces and electrical compartment areas. System requires airflow restoration through filter replacement or ductwork evaluation, complete defrost cycle, and verification of proper refrigerant charge once ice has melted to restore normal heating operation.
