Clean the spark electrode with fine emery cloth to remove carbon buildup.
With the updated schematic, troubleshooting often reveals that a "faulty board" is actually a failing safety device or poor wiring connection. 1. "Check" Light Illuminated (No Propane Operation) rm28525 schematic diagram updated
: It manages power distribution, including the high-voltage power supply (HVPS) for the toner transfer process and the low-voltage supply for the formatter and sensors.

The 12V DC path travel through a thermal limit switch (thermofuse) mounted on the burner flue. If the flue overheats, this switch opens and cuts all power to the board.
Before we dive into the search, let's establish what you're looking for. A schematic diagram is a visual map of an electronic circuit, using standardized symbols to represent components and their electrical connections. It serves as the blueprint for the device, essential for troubleshooting, manufacturing, or learning. However, for a product like a complete computer, a "schematic" could refer to a circuit diagram for an internal component—such as the motherboard or power supply—rather than a single diagram for the entire system.
