The Raypak 008093F is a manual reset high limit switch designed for critical thermal protection in Raypak commercial boilers and hydronic heating systems. Engineered to function as a fixed safety control, this 200F limit switch monitors internal water temperatures and triggers an immediate system shutdown if the 200°F threshold is exceeded, preventing hazardous overheating and equipment fatigue. As a genuine Raypak OEM part, the 008093F ensures exact mechanical fitment and electrical compatibility, maintaining the industrial safety standards required for HVAC high limit controls. This Raypak 200F high limit features a manual reset (M/R) mechanism, necessitating onsite inspection by a technician before the system can be restored to operation—a vital safeguard for identifying the root cause of high-temperature excursions. Built for durability in demanding boiler rooms, the switch provides reliable thermal protection across various Series 1005 to 4005 Raytherm and Xtherm models. Replacing a fouled or non-responsive boiler safety switch with this factory-spec component restores the integrity of the secondary safety loop. Key Benefits Thermal Safety: Fixed 200°F temperature cut-off prevents catastrophic overheating and boiler vessel damage. Manual Reset Mechanism: Ensures thorough system diagnostics by a contractor before resuming operation. OEM Precision: Direct replacement for Raypak 008093F keeps equipment within original engineered specifications. Broad Compatibility: Integrated into various Raypak commercial hydronic and pool heating platforms. Rugged Construction: Industrial-grade components designed for high-cycle reliability in high-temperature environments. Common Questions What causes a manual reset limit switch to trip? Tripping typically indicates a flow restriction, a malfunctioning operating controller, or excessive scale buildup within the heat exchanger. The 200°F threshold is a safety limit that should not be reached during normal modulation. Can I use a different temperature rated switch? No. Safety controls must be replaced with the exact temperature rating specified by the manufacturer to maintain the designated safety profile of the appliance. Does this switch provide automatic reset? No, the 008093F is a manual reset model (M/R). Once the 200°F limit is breached, a technician must physically depress the reset button after the temperature has dropped to safely restart the burner.
