What is bimetallic thermostat?
Bimetal Thermostats, which regulate the temperature inside heating pads, blankets, and medical pads, are used in any case where the applications need control for a low temperature. Bimetal Thermostats use two different kinds of metal to regulate the temperature setting.
How does a bimetallic thermometer work?
Bimetal thermometers work on the principle that different metals expand at different rates as they are heated. By using two strips of different metals in a thermometer, the movement of the strips correlates to temperature and can be indicated along a scale.
Why is bimetallic strip used in a thermostat?
A bimetallic strip is used to convert a temperature change into mechanical displacement. The strip consists of two strips of different metals which expand at different rates as they are heated.
How do you test a bimetallic thermostat?
Things You Will Need
- Locate the bimetal thermostat.
- Turn on the furnace or device and adjust the temperature control to turn it on.
- Plug in the hair dryer and aim the flow of heat at the bimetal thermostat.
- Replace the bimetal thermostat if it does not respond correctly to heat.
- Turn the hair dryer off and unplug it.
Is bimetallic a thermometer?
A bimetallic thermometer is a temperature measurement device. It converts the media’s temperature into mechanical displacement using a bimetallic strip. Bimetallic thermometers are used in residential devices like air conditioners, ovens, and industrial devices like heaters, hot wires, refineries, etc.
What are the symptoms of a bad defrost thermostat?
A faulty defrost termination thermostat may result in the defrost heater never heating and a solid frost buildup on the evaporator coil, which results in too warm temperatures. The thermostat contacts are normally closed and have continuity until it reaches 140 degrees.

What happens to the coil inside a thermostat when it is cooled?
Each metal responds to heat and cold by expanding a specific amount based on the change in temperature. When heat is applied to the coiled bimetallic strip, it expands and uncoils. The strip shrinks and coils tighter in response to applying cold temperatures.
