The defrost auto reset bimetallic control / Moisture Resistant Temperature Control from LANCOR offers proven reliability in a moisture resistant design. A defrost thermostat is a device that limits how much heat is applied to the defrost heaters typically found in refrigeration units. They allow current to flow when they reach a certain low (cut-in) temperature.

Defrost Thermostats / Moisture Resistant Bimetal Control
The defrost auto reset bimetallic control / Moisture Resistant Temperature Control from LANCOR offers proven reliability in a moisture resistant design. A defrost thermostat is a device that limits how much heat is applied to the defrost heaters typically found in refrigeration units. They allow current to flow when they reach a certain low (cut-in) temperature. During the defrost cycle, they in-turn pass current to the defrost heaters. When the heaters cause the evaporator coils to reach a certain (cut-off) temperature, the moisture resistant thermostat cuts-out and stops the current flow to the defrost heaters. The snap-action of the bi-metal disc provides high-speed contact separation resulting in excellent life cycle characteristics at electrical loads up to 10 amps at 120VAC and 5 amps at 250VAC. The sealed design provides moisture resistance for moisture prone environments. A wide variety of terminal, lead wire and mounting configurations are available to provide maximum design flexibility. The defrost thermostats are the most popular and widely applied temperature control in refrigeration applications such as defrost termination and ice cube maker control. It is also applied in a range of heat pump and air conditioning applications. This action protects the refrigerator and the consumer from hazardous conditions and unnecessary power usage. Defrost thermostats fail often due to the large temperature swings that they are subject to.
Refrigerator defrost thermostat is used for temperature control during defrost in the refrigerator or the ice machine, which can be used for automatic temperature controls in the refrigerator heating compensation and electric heating defrosting. Its structure features application of resin to completely seal the electric parts, allowing to be installed in a narrow space and boasting humidity-proof and wet-proof.
