A single shot thermostat switch is designed to work only once. They are sometimes used in applications where the manufacturer doesn’t want to the end user to try and make repairs to a system. However, this can be inconvenient if you’re an end user! Luckily, there is a way to reset a single shot thermostat.
The switch won’t reset under normal circumstances, but it can be reset using extreme cold. The best way to do this is by using dry ice, which can be found at your local Walmart. The switch needs to get down to about -40°F to reset, so regular ice isn’t nearly cold enough. Just remember to be careful when handling dry ice, as it has a temperature of below -100°F. Be sure to NEVER touch the dry ice with your bare hands. Hold the dry ice to the switch until you hear a snap, and your switch will be ready to use again. It’s easy as that!
