Refrigerator thermostats work by measuring the amount of warm air present within the unit and cycling it through a cooling mechanism to achieve the desired temperature. The warmth threshold can be set through a dial within the refrigerator.Know More
It is a common misconception that refrigerators maintain a cold temperature by cycling cold air into the unit. Refrigerators don’t actually place new air into the unit, but use the thermostat to monitor temperature and cool the warm air that builds up over time.
Proper use of a refrigerator thermostat begins by setting it at the appropriate temperature. In most cases, a dial is found within the main interior of the unit, usually at the top center. Older models featured actual degrees on the dial, with newer models switching to a numerical ranking system that correlates to an approximate temperature. In order to understand what temperature each number represents, owners can refer to the refrigerator's instruction manual.
Once the thermostat detects the designated amount of warm air, it activates the internal compressor that pumps that warm air out of the storage section of the unit. The air is transferred to a series of coils that connect to a supply of coolant. As the air travels through this coiled piping, it drops in temperature and is fed back into the main body of the unit.Learn more about Appliances
A freezer and fridge work the same way by using a refrigerant to move heat from inside the unit to the outside. In combination units, air from the freezer is used to cool the refrigerator compartment.Full Answer >
William "Refrigerator" Perry, the former defensive lineman for the Chicago Bears, weighed 350 pounds while an active player. Perry was a first-round pick for the Bears in 1985 and helped the team win Super Bowl XX in his rookie season.Full Answer >
If a water heater is electric, the circuit breaker switch that feeds electricity to that circuit turns the unit off, and if it is gas, turning the thermostat dial to Off shuts the power off. This knowledge is crucial when the water heater starts to make menacing noises.Full Answer >
A repair may be more affordable if the unit is newer and the thermostat breaks, valve sticks, pilot light goes out, circuit breaker trips, or heating element fails. If the unit is leaking or is more than 10 years old, it is best to replace it.Full Answer >
