If you’re like most people, you probably have a thermostat in your home. It’s probably on the wall by the front door, or in a cabinet near the oven. If you don’t have one, you can buy one at a hardware store. The thermostat is an important part of your home’s heating and cooling system. It sets the temperature of your home’s room or office, and it can also be used to control the temperature of your car. To test your thermostat, first make sure that it’s working properly. If it isn’t, fix it as soon as possible. Then test your car’s thermostat by turning on the heat and then turning off the heat. The thermostat should keep the car at its original temperature no matter what!
