No.
The thermostat senses the actual temperature in the fridge and compares it to the desired temperature (which the user sets on a dial), if the actual is above the desired it signals the compressor motor to run until the desired temperature is reached, when it stops the motor.
It's in the thermostat housing between the actual thermostat and heater hose. Has a little insulated wire coming out of it.
this could be as a result of failed thermostat, since they now fail-safe ie they're opened to allow water to circulate freely.
That depends entirely on the calibration of the sensor and the display. The actual engine temperature is controlled by the thermostat.
You can determine if a thermostat is bad by checking for inconsistent temperature readings, where the actual room temperature differs significantly from the set temperature. Additionally, if the heating or cooling system fails to respond to the thermostat's settings or cycles on and off frequently without reaching the desired temperature, it may indicate a malfunction. Inspecting for physical damage, loose wires, or corrosion can also help identify issues. If these signs are present, replacing the thermostat may be necessary.
A 160-degree thermostat is designed to open at approximately 160 degrees Fahrenheit. This means that when the engine coolant reaches this temperature, the thermostat will begin to open, allowing coolant to flow from the engine to the radiator. This helps regulate the engine's temperature and prevents overheating. It's important to note that the actual opening temperature can vary slightly due to manufacturing tolerances.
You can tell if a thermostat is working properly by checking if the temperature displayed matches the actual room temperature, if the heating or cooling system turns on and off as expected, and if the programmed schedule is being followed accurately. If you suspect a problem, you may also consider calibrating or replacing the thermostat.
Negative feedback is a reaction that causes a decrease in function. Using a thermostat, it senses the temperature of an area and responds by either turning on or off the heater or air conditioner.
Turning the thermostat to a higher temperature does not make the air coming out of the vents hotter on a central AC with a heat coil. The temperature setting on the thermostat simply tells the system when to stop cooling or heating, but it doesn't affect the actual temperature of the air being produced. The heat coil or furnace is responsible for heating the air, not the thermostat setting.
P0128-THERMOSTAT RATIONALITY When Monitored: The engine running. During cold start. Set Condition: The PCM predicts a coolant temperature value that it will compare to the actual coolant temperature. If the two coolant temperature values are not within 10°C (50°F) of each other an error is detected. Basically your thermostat has failed.
If the temperature gauge is to remain up past the 260 mark, there could be many problems. If no problems are in existence then the simple work of replacing a fuse or wire could correct the thermostat to show the actual temperature.
