Robertshaw 5300-793 Temperature Control

The Robertshaw 5300-793 is a rugged, snap-acting thermostat designed specifically for demanding commercial cooking and HVACR applications. Operating as a single pole single throw (SPST) control, this Type KX electric thermostat offers precise regulation across a 100°F to 450°F temperature range. Engineered for pilot duty 120/277V AC circuits at 50VA, it features high-grade silver contacts and heavy-duty terminals to ensure consistent electrical continuity in high-ambient environments. The 30-inch capillary and 3/16" x 11-5/8" nickel bulb allow for flexible sensor placement in fryers, ovens, and sterilization tanks. This direct-acting control is a verified commercial cooking thermostat replacement for Vulcan-Hart, Southbend, and Bakers Pride units. Whether you are performing a field repair or a mid-cycle retrofit, the Robertshaw 5300 Series provides the mechanical reliability and 6°F differential accuracy necessary to maintain critical equipment setpoints and minimize short-cycling.

Key Benefits

• Broad Compatibility: Functions as a direct cross-reference for leading OEM brands including Vulcan-Hart 810071 and Southbend 1055800.
• Enhanced Durability: Utilizes a snap-action mechanism and silver contacts to prevent arcing and extend component life under heavy loads.
• Precision Calibration: Features an adjustable dial stem for fine-tuning setpoints, maintaining a tight mechanical differential for temperature stability.
• Flexible Installation: The 30" capillary length and standard 4-way dial type simplify integration into diverse equipment configurations.

Common Questions

What equipment is this thermostat compatible with?
This Robertshaw 5300-793 is a KX-97-30 type control often found in Vulcan-Hart, Hobart, and Bakers Pride commercial ovens and ranges. Always verify the capillary length and temperature range of your existing unit before replacement.

Can I use this for millivolt systems?
No, this model is rated for pilot duty 120/277V AC. For millivolt applications, you require the RX series which uses a hermetically sealed reed switch.

How do I handle a temperature overshoot?
If the equipment is exceeding the setpoint, ensure the bulb is properly seated in its bracket and fully immersed in the medium. You can adjust the calibration screw on the dial stem (clockwise to decrease) if the reading is consistently high.
