Robertshaw 5300-765 Thermostat

The Robertshaw 5300-765 is a high-limit pilot duty thermostat designed for demanding commercial foodservice applications, specifically engineered for high-temperature equipment like deep fat fryers and industrial ovens. This SPST break-on-rise surface mount control operates within a temperature range of 175°F to 500°F (79°C to 260°C). It utilizes a 36-inch copper capillary and a 3/16" x 11-1/2" nickel-plated bulb for precise thermal sensing. As a 5300 Series Robertshaw control, it functions as a manual reset safety switch, ensuring the pilot circuit is interrupted if temperatures exceed the set limit. The mechanical construction features a robust dial shaft and rugged housing, making it a reliable OEM replacement thermostat for technicians servicing commercial kitchens. Proper installation requires ensuring the capillary is not kinked to maintain bulb pressure and calibration accuracy during high-load heavy-duty cycles.

• Wide Temperature Range: Covers 175°F to 500°F, making it a versatile commercial kitchen thermostat for various cooking appliances.
• Manual Reset Safety: Essential for code compliance in high-limit applications, preventing automatic restarts in over-temperature conditions.
• Extended Capillary Reach: The 36-inch lead allows for flexible mounting in dense equipment chassis while maintaining the bulb in the heat zone.
• Pilot Duty Reliability: Specifically rated for pilot circuit interruption, ensuring fail-safe operation in gas-fired systems.
• Durable Construction: Nickel-plated bulb resists corrosion and carbon buildup common in kitchen environments.

How do I test the Robertshaw 5300-765 for continuity?
With the system cool, check for continuity across the terminals. Since this is a manual reset device, if the circuit is open, press the reset button until it clicks before re-testing. If it remains open at room temperature, the element has likely lost its charge.

Can this thermostat replace an automatic reset model?
No. In high-limit safety applications, a manual reset is required by safety standards to ensure a technician inspects the cause of the overheat condition before the equipment is put back into service.

Is the bulb compatible with all fryer oils?
Yes, the nickel-plated copper bulb is designed to withstand the chemical breakdown and high temperatures associated with standard commercial frying oils and cleaning agents.
