Abstract
A thermostat is positioned within a scroll compressor such that a thermostat switch is positioned in the non-orbiting scroll, and a body of the thermostat extends through the crankcase. The thermostat communicates with a heater associated with a motor protector circuit. Current is directed to the heater causing the heater to more promptly stop operation of the scroll compressor. A bias element holds the thermostat securely within the crankcase and non-orbiting scroll such that it will not rattle during operation. Several embodiments of the thermostat are disclosed.
