Supco ML80 Defrost Thermostat L80-50F SPST 60T11 Style 611448

The Supco ML80 is a professional-grade defrost thermostat designed for refrigeration applications including ice makers, refrigerators, and freezers. This bimetal disc temperature control features a compact 3/4-inch (19mm) sealed design that provides proven reliability and moisture resistance in demanding refrigeration environments.

Key Features:

• Temperature range: Opens at 80°F, closes at 30°F (L80-50F configuration)
• SPST (Single Pole Single Throw) switch with open-on-rise action
• Electrical rating: 10 amps at 120VAC, 5 amps at 250VAC
• 12-inch insulated wire leads (#18 AWG stranded copper)
• Differential: 30°F ±4°F for precise defrost cycle control
• Sealed moisture-resistant construction for long-term durability
• Manufactured by Therm-O-Disc to OEM specifications

This defrost termination thermostat controls the defrost cycle by closing the heater circuit to initiate defrosting and opening the circuit when the temperature rises above the setpoint. This prevents ice buildup while protecting refrigerated contents from excessive heating. The ML80 is designed for surface or flush mounting in evaporator compartments and serves as a direct replacement for OEM part numbers GL80 and AP4502983.
