Raypak 015023F Manual Reset Limit Switch for Combustion Chamber

The Raypak 015023F is an OEM manual reset (M/R) limit switch designed for use in the combustion chamber of Raypak boilers, pool heaters, and hydronic heating systems. This critical safety component continuously monitors combustion chamber temperatures and protects the heating system from overheating and potential heat-related damage.

How It Works:

The limit switch interrupts the electrical circuit when internal combustion chamber temperatures exceed the switch's preset threshold. Once tripped, the system requires a manual reset — meaning a technician or qualified operator must physically inspect the system and press the reset button to restore operation. This deliberate design ensures any underlying cause of overheating is identified and resolved before the unit is returned to service.

Key Features:

• Manual reset (M/R) operation requires user intervention after tripping — preventing automatic restart without inspection
• Designed specifically for combustion chamber temperature monitoring and protection
• Acts as a high-limit safety device, cutting power to the burner circuit upon over-temperature detection
• Genuine Raypak OEM replacement part (MPN: 015023F)
• Compatible with select Raypak boiler, pool heater, and water heating system models

Always verify fitment against your specific Raypak model and serial number when ordering replacement parts. Installation should be performed by a licensed HVAC or pool heating technician in accordance with applicable local codes.
