How do you reset a snap disk thermostat?
If it’s a manual reset thermostat switch, press the red button found on the thermostat switch to reset. Manual reset thermostat switches will not reset by themselves, and require human intervention to reset. If it’s a one shot thermostat switch, the switch needs to be replaced.
Is a snap disc a bimetal?
Snap Disc Thermostatic Bimetal is typically a very thin material (t < 0.3mm) that is formed into a concave element. The element is heated either by changes in ambient temperature or through internal resistive heating in current carrying applications.
What is a bimetal disk?
This disc is made from a laminate of two different metal alloys with different coefficients of thermal expansion. The disc changes instantly from a concave to a convex shape when it is heated above its activation temperature. It changes back again when it cools.
What does a Thermodisc do on wood stove?
This helps regulate temperature more evenly and uses the stove’s heated air only as needed. The thermodisc comes with an 8-foot long power cord and installation is simple, making this a useful and easy addition to all sorts of freestanding wood stoves.
What does a snap disc do in a pellet stove?
This part may be called a limit switch, snap switch, or snap disc. These temperature sensing switches serve as a safety feature and typically control auger motors, blowers, and other major components in your stove.
What is manual reset thermostat?
Comstat’s temperature limiting manual reset thermostats are a temperature sensitive device with normally closed contacts. The contacts open at a factory set temperature and the reset is achieved by manually pressing the button.
What is a snap disc on a pellet stove?
This part may be called a limit switch, snap switch, or snap disc. These temperature sensing switches serve as a safety feature and typically control auger motors, blowers, and other major components in your stove. Depending on the brand and model, you may have multiple high and/or low limit switches.
How does a bimetal switch work?
The bimetallic strip consists of two thin strips of different metals, each having different coefficients of thermal expansion. Thermal expansion is the property of a metal to change its shape or volume with a change in temperature. The metal strips are connected along their length by fusing them together or riveting.

How do bimetallic strips work?
The bimetallic strip constitutes one of the most trouble-free and durable thermometers. It is simply two strips of different metals bonded together and held at one end. When heated, the two strips expand at different rates, resulting in a bending effect that is used to measure the temperature change.
What are the instruments used in bimetallic strip?
Thermometer and thermostat are examples of bimetallic tip devices. (i) Thermometers: A thermometer uses a bimetallic strip, generally wrapped into a coil in its most used design. The coil changes the linear movement of the metal expansion into a circular movement due to the helicoidal shape it draws.
