# A DIY Refrigerator Thermostat
Most refrigerator thermostats do not allow the user to set a specific temperature. The dials allow the user to set the coldness on a scale of 1 to 5 or 1 to 10. This can make it difficult for maintaining the optimal temperature range in your refrigerator. Using a few household items, you can create a homemade thermostat for monitoring the temperature to the exact degree. With this knowledge, you can ensure your food and drinks stay fresh and safe.
