Appliance Thermostats
All Appliance has some kind of a temperature controller in them to regulate the heat or cold build-up in them.

| Stove and refrigerator Thermostats |
Thermostats are nothing more than a on/off switch with a intelligence which can control a predetermined temperature for Appliances like Refrigerators, Ovens, Microwaves, washing machines, tumble dryers and even GHD's has it.
Most people tend to think that a thermostat works the same as a water-tap; -
Refrigerator compressor and stove elements only work at 100% capacity - circulating refrigerant (gas) at full speed. The same with a oven element it only works full blast.
Once electric power is connected to a heating element it will go red-red hot till you cut the electricity by using a on/off switch(wall plug) or regulator( stove plate switch) and lastly a thermostat. Same with a compressor it only pumps gas full speed.
so you see there is no such thing as heating element or compressor operating on a slower
speed.
There are so many thermostat variouses on the market but I will just cover some of the more popular types we use in repairing everyday appliances.
I just need to get this out of the way first, a stove plate/element regulator (switch) is not a thermostat but I will tell more about them in another post.

If you turn the thermostat setting higher more coldness or heat will flow.
Nothing can be more further from the truth

- Mechanical thermostat; Used in Refrigerators and Ovens
- Electronic thermostat(module); Fridges like Defy has them and the new generation ovens of samsung and whirlpool
- Thermistor; used in GHD's, toaster, irons and kettles
- Capillary; A Thin tub filled with gas which reacts with temperature changes
- Sensor probe: Attached to one end of the capillary tub one and connected to the unit you want to control.
- Controller; Other end of capillary is connected to controls and the knob has number on it giving you the impression that you are increasing or decreasing "something" . .
Should you need more information write me an email.
