Electric 481600 High-Limit Upper Water Heater Thermostat

The Electric 481600 High-Limit Upper Water Heater Thermostat is an upper electric water heater thermostat with high-limit reset protection. It is used on compatible dual-element electric tanks where the upper thermostat controls the first heating stage and safety cutoff.

This service part differs from a lower thermostat because it includes the resettable high-limit function and manages element sequencing. It should be matched to the heater’s original thermostat style and wiring diagram.

Product Features:

• Upper Control Location: Installs in the upper thermostat position on compatible dual-element electric water heaters.
• Manual High-Limit Reset: Includes the safety reset function that interrupts power during overheating conditions.
• Double-Throw Sequencing: Upper thermostat directs power priority between the upper and lower elements.
• Therm-O-Disc 59T/66T Style: Replacement references associate this upper control with common Therm-O-Disc formats.
• 120–480V Rating Range: Distributor references list broad electric water heater voltage compatibility.
• Service Diagnostic Part: Used when no-hot-water, tripped reset, or upper element control faults are diagnosed.
• Upper Element Priority: Restores top-of-tank heating first before allowing lower tank recovery.

Warranty

This service part includes a manufacturer’s limited warranty. Disconnect power and verify thermostat type, voltage, wiring, and water heater model before replacement.
