White-Rodgers 756-1 Thermostat

The White-Rodgers 756-1 is a commercial-grade SPDT electric water heater thermostat designed for precise surface-mount temperature sensing. Engineered for high electrical capacity, this Single Pole Double Throw control is frequently used in residential and light commercial storage tank systems to manage upper and lower heating elements. With a temperature range of 110°F to 150°F and a fixed high-limit safety cut-off at 170°F, it provides reliable switching for 120-277 VAC resistive loads. The snap-action contacts minimize arcing, ensuring longevity in high-amperage plumbing applications.

For technicians in the field, the White-Rodgers 756-1 offers a rugged solution for electric water heater repair where a manual reset safety is required. Its 30-amp rating at 240V accommodates standard heating elements, while the surface mount design allows for direct contact with the tank wall for fast thermal response. This unit is often paired with the 755-1 to provide a complete primary and secondary control circuit on dual-element tanks.

• High Electrical Capacity: Rated for up to 30 Amps at 250 VAC, making it ideal for standard resistive heating elements.
• Snap-Action SPDT Switching: Ensures rapid contact movement to reduce wear and provide consistent temperature regulation between 110°F and 150°F.
• Integrated Manual Reset: Features a fixed 170°F high-limit safety that must be manually reset if the tank exceeds safe operating temperatures.
• Universal Surface Mount: Standard mounting bracket configuration allows for easy field replacement on most major residential water heater brands.

Is the White-Rodgers 756-1 compatible with 240V dual-element water heaters?
Yes, this SPDT control is specifically designed to manage the switching between the upper and lower elements in a standard residential dual-element configuration, provided the amperage does not exceed 30A.

What is the difference between this and a standard SPST thermostat?
Unlike a Single Pole Single Throw (SPST) unit, the SPDT 756-1 features three terminals, allowing it to divert power from the upper element to the lower element once the top of the tank reaches the set temperature.

How do I reset the high-limit safety on this unit?
If the water temperature hits 170°F, the safety will trip. Once the water cools, you must manually depress the red reset button to restore power to the heating circuit.
