Types of Coffee Maker Thermostats
Most coffee makers have two control systems. The first of the control systems is either a Snap Disc thermostat or a Capillary thermostat. A Snap Disc thermostat is normally found in household coffee makers and has a fixed temperature setting. A Snap Disc is normally the least expensive option. A Capillary thermostat on the other hand has an adjustable temperature range and is commonly found in larger industrial coffee makers.
The second type of control system is the high limit. The high limit prevents your coffee maker from burning up when it runs out of liquids, or if the heater were to malfunction. The high limit control is typically a Snap Disc thermostat or a Thermal Fuse. If the temperature becomes too high for the unit to withstand, the Snap Disc or Thermal Fuse will open the incoming power control circuit and turn of the equipment. Keep in mind, some newer units may be using a digital thermostat instead of a Snap Disc or Capillary Thermostat.
How To Test If Your Coffee Maker’s Snap Disc Needs To Be Replaced.
Testing your coffee maker to see if the high limit has been reached is actually pretty simple.
- First, unplug the unit from the incoming power,
- Remove the wires from the thermostat.
- Run a continuity test across the terminals on the high limit.
If you notice that you do not get a light, that indicates that the circuit is open which indicates that the high limit has been set off.
Most coffee makers have a one-shot snap disc thermostat and once the high limit is hit, it will need to be replaced. However, a higher priced unit might have a snap disc thermostat that is a manual reset. In this case, all you need to do is push the reset button.
