A thermos is a versatile and essential item for keeping beverages at the desired temperature, whether it’s for daily commutes, outdoor adventures, or simple office use. However, like any other product, a thermos can sometimes malfunction or fail to perform as expected. If your thermos is not working, it can be frustrating, especially if you rely on it to keep your drinks hot or cold throughout the day. The good news is that many issues with thermoses can be easily resolved with some basic troubleshooting and maintenance. In this article, we will delve into the common reasons why a thermos might not be working and provide you with practical tips on how to fix these issues.
Understanding How a Thermos Works
Before we dive into the troubleshooting, it’s essential to understand the basic principle behind a thermos.
