The RAM‑1MC1‑01 is a heat‑control module used in direct spark ignition (DSI) fireplace systems, providing 24/120/240 VAC power to the igniter and burner valve circuits. Common failure points include burned or cracked input/output traces on the PCB, failed MOSFETs or driver ICs that control the spark generator, and degraded capacitors or diodes in the power‑conditioning section. First‑check diagnostics: verify proper mains voltage at the module’s input terminals; inspect the board for visual damage such as burn marks, loose solder joints, or cracked components; and review any diagnostic LEDs or error codes displayed on the panel to isolate the fault before proceeding with component replacement.[oss-gpt-20b]
