Thermostats 1 Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12829
Jlab Export is a leading Thermostats 1 Manufacturer,and suppliers in India
For single-door, direct-cool refrigerators, this thermostat controls the refrigeration compartment between -5 and 10 °C. Its sensing tube sits against the evaporator. The contacts start the compressor as the cabinet warms and stop it once the dial setting is reached. The fridge then cycles around the chosen temperature.

Lab Exercises with a Refrigerator Thermostat
Students first find the contact terminals and test them with a Digital Multimeter set to continuity. At room temperature the contacts should be closed. They then lower the sensing tube into a beaker of ice and water beside the probe of a Digital Stem Thermometer. The reading at which the contacts open is the cut-out. Adding salt takes the bath below 0 °C for the colder dial positions.
Letting the bath warm slowly shows the cut-in point, and the gap between the two readings is the differential. The thermostat is then wired in series with the compressor supply on a Basic Refrigeration Training Unit, where the class watches it cycle the compressor.
Frequently Asked Questions
What do cut-in and cut-out mean on a thermostat?
Cut-out is the temperature at which the contacts open and the compressor stops. Cut-in is the higher temperature at which they close again and the compressor restarts. The gap between the two, called the differential, keeps the compressor from short cycling.
Can this thermostat be used in a freezer?
No. Its range of -5 to 10 °C suits the refrigeration compartment of a direct-cool fridge. For a freezing compartment, Thermostats 3 works in a much colder band.
How do I fit a replacement thermostat?
Switch off and note the wiring on the old unit before removing its knob and screws. Place the new sensing tube where the old one was, without kinking it, connect the wires as before, refit the knob and check that the compressor cycles.
How can I tell if the thermostat has failed?
With the sensing tube warm, the contacts should show continuity. If they stay open at room temperature, or stay closed when the tube is chilled well below the setting, the thermostat is faulty. A cracked or leaking sensing tube also stops it working.
