A refrigerator thermostat is essential for keeping food fresh because it regulates the temperature inside the fridge. In such a case, you don’t want to wait until the day before your trip or event to test whether the thermostat is working properly. How should you go about testing the thermostat?
Refrigerators with a thermometer built-in usually come equipped with a plug that allows you to check the temperature from outside the appliance, but some models include only a simple push button switch instead. This article provides step-by-step instructions on how to safely test a refrigerator thermostat to ensure its reliability.
Testing the refrigerator thermostat involves removing the door cover, locating the push button control panel, turning off the breaker and then checking the temperature using a room thermometer. The steps are illustrated in video format to provide visual guidance.
How to test a refrigerator thermostat?
A refrigerator thermostat helps regulate the temperature inside the fridge and freezer during operation. It measures how cold the air around the compressor is and uses this data to determine if and when the compressor needs to run. This function is very important because running the compressor when not needed wastes energy and could possibly harm other parts of your appliance. Thermostats used on refrigerators are typically analog devices composed of two metal plates.
One plate heats up while the other stays relatively cool. These plates act as resistors. Their resistance varies depending upon whether they are hot or cold. By measuring these changes in resistance, the thermostat can determine whether the compressor needs to run based on ambient temperature. As far as testing goes, you should disconnect any power source from the refrigerator and plug a voltmeter into the terminals near the thermostat. Next, check the resistance between the hot and cold plates of the thermistor. A range anywhere from 0Ω to 10Ω is ideal. Anything outside the normal range indicates a faulty thermostat.
How does a refrigerator thermostat work?
A refrigerator thermostat works by measuring and controlling the temperature of the interior of the fridge. It functions by reading the temperature of the air inside the fridge, using a thermoelectric sensor. These sensors convert heat into electrical current and measure the current produced by the change in temperature. When temperatures deviate from a certain range, the refrigeration system will turn off to prevent damage to the compressor and other components of the unit.
Why do refrigerator thermostats fail?
Most modern refrigerators have a built-in temperature sensor located somewhere in the back of the appliance. This sensor measures the actual temperature inside the fridge and sends this information via wire to the main board. A series of relays then turns on the compressor if the temperature within the cabinet goes above or below certain set points. If the sensor fails, it could result in the compressor running continuously until the unit overheats. It is not uncommon for sensors to go bad from normal wear and tear. Also, if the compressor does not shut off after completing the cooling process, the compressor could eventually burn out if it continues to run for long periods of time.
How do I know if my refrigerator thermostat is bad?
There are two common symptoms associated with faulty refrigerators. Cold air comes from the compressor, not the evaporator coil. This occurs because the evaporator coil is located at the top of the freezer where the cold air cools and condenses. To correct this problem, open the door and remove the coils (usually screws). Then turn off the power switch and leave the refrigerator unplugged until the next repair visit.
Failing to replace the thermal fuse in the line between the compressor and the circuit breaker can lead to overheating. A failed thermal fuse can result from a damaged wire or a loose connection. Turn off the power switch, disconnect the appliance and check the wiring connections. Check for burned wires. Replace any broken wires with new insulated copper wire. Once replaced, reconnect the power source and test the system. If no improvement is detected, contact the service department for further assistance.
How do I troubleshoot a refrigerator thermostat?
Thermostats are very important components in refrigerators; particularly if they’re not working properly. Thermostats typically operate based on a system called “heat transfer” (as opposed to “air displacement”). This type of thermostat measures the difference between the air temperature where a person touches versus the surface temperature of the freezer or fridge. An improperly functioning thermostat could result in cold spots in the fridge, freezer and even hot spots in the freezer. It could potentially lead to spoiled food and mold buildup within the freezer. Most of these problems stem from the failure of the thermostat itself, however some of the possible solutions include replacing the thermostat sensor, cleaning the thermistor coils near the baseboard, wiping down any condensation that builds up around the unit, checking the wiring connections and making sure the power cord connection is secure.
How do I reset a refrigerator thermostat?
A thermostat controls the interior temperature of a refrigerator. It changes the compressor’s operation based upon the temperature reading from sensors located within the unit. Thermostats can be found behind the doors (often labeled “Refrigeration Control”), but if yours doesn’t show up in that location, try looking under the base cabinet next to where the freezer door opens. A typical refrigerator thermostat consists of two sets of wires. One set connects between the sensor board and the compressor; the other, from the sensor board to the control panel.
To reset the thermometer, follow these steps: Turn off the power switch. Remove the front cover from the appliance. Disconnect each wire individually, starting with the one closest to the compressor. Using tweezers or needle nose pliers, grasp the wires firmly. Twist them until they unplug from the back side of the sensor board. Replace the board into place and replace the front cover. Turn the power switch on again. Reset the temperature setting to the desired level.
If the thermostat is not working correctly, check for loose connections and broken wires. Check that the thermostat is plugged into a receptacle grounded to metal, such as a junction box. Do not plug any electrical devices directly into the outlet used for the refrigerator. Make sure the sensor board is properly connected to the circuit breaker. If the problem continues after troubleshooting the wiring, contact a certified service technician.
You’ve probably heard of thermostats before, but did you know they can also control your refrigerator?
