ODM Thermal Fuse Bimetal Thermostat Switch Home Appliance Parts 6615JB2002A

Short Description:

Introduction：Defrosting Thermostat Fuse 6615JB2002A

The defrost thermostat differs from the refrigerator thermostat, which is the temperature gauge used to regulate the cooling system of the refrigerator. This device works to measure internal temperatures and prevents the refrigerator from becoming too hot or too cold.

Function: temperature control

Operating Principle

Bimetal disc thermostats are thermally actuated switches. When the bimetal disc is exposed to its predetermined calibration temperature, it snaps and either opens or closes a set of contacts. This breaks or completes the electrical circuit that has been applied to the thermostat.

There are three basic types of thermostat switch actions:

•Automatic Reset: This type of control can be built to either open or close its electrical contacts

as the temperature increases. Once the temperature of the bimetal disc has returned to the specified reset temperature, the contacts will automatically return to their original state.

•Manual Reset: This type of control is available only with electrical contacts that open as the

temperature increases. The contacts may be reset by manually pushing on the reset button after the control has cooled below the open temperature calibration.

•Single Operation: This type of control is available only with electrical contacts that open as the

temperature increases. Once the electrical contacts have opened, they will not automatically reclose unless the ambient that the disc senses drops to a temperature well below room temperature (typically below -31°F).
