Ranco Thermostat

The Ranco Thermostat protects the power feed to the compressor clutch and is located on the on the right side of the evaporator case behind the dash under panel.  

The Ranco Thermostat is designed to sense temperature of the system at the evaporator, preventing evaporator freeze-up.  The thermostat is conductive in all modes and functions except when evaporator temperature falls below 2°C (36°F) or when overridden by Ranco override switch in high ambient situations.  When this occurs, the electrical feed is disconnected to the compressor clutch eliminating the refrigeration cycle until the evaporator warms to above 2°C - then the refrigeration cycle will restart.


Item is original used and tested for functionality.

Our work


Jag-Aire, LLC is a manufacturer of replacement Delanair MKII Air Conditioning control amplifiers and other accessories for 1974-1987 Jaguar XJ6, XJ12, and XJS Series 2 & 3 luxury vehicles.


As an avid owner and collector of Jaguar automobiles, I became tired of sweating in the summer heat or freezing in the winter cold because my XJ-S AC amplifier had a mind of its own.  Discouraged that I had to resort to 30 year old used AC amplifiers, because new amplifiers were not available; I began developing my own replacement.  


Jag-Aire, LLC was born in 2016 to bring quality replacement AC amplifiers and accessories to other Jaguar Enthusiasts.
