Why does my thermostat not read the temperature?

Why does my thermostat not read the temperature?

A broken thermostat will throw your temperature gauge off. Because the thermostat restricts the flow of coolant through the radiator, it typically gives accurate readings of the temperature. However, if the thermostat gets stuck open and is no longer able to restrict the flow, it may continue to read cooler than the actual temperature.

What should you do if your temperature gauge is not working?

The first thing you always need to look at with a strange reading on your temperature gauge is giving a strange reading is the actual temperature of your engine. Always rule that out first before focusing on the gauge itself. If you know the engine temperature is not an issue, you probably have to deal with one of these problems;

Do you have a bad thermostatic temperature control?

If you have a refrigerator that never cycles on or a refrigerator that runs continuously, freezing everything in the refrigerator and freezer compartments, the chances are good that you have a bad thermostatic temperature control.

Is it dangerous to test a thermostat?

Of all the possible causes, the thermostatic control is one of the easiest to test. There are dangers involved in any type of do-it yourself project if the proper safety precautions are not taken. Working with electricity is especially dangerous because you cannot see it with the naked eye, so always unplug an appliance before working on it.

When does the engine temperature warning light come on?

When working properly, the cooling system keeps the engine running at peak efficiency and at its ideal operating temperature. Upon starting, the engine temperature warning light should come on and then go off in two seconds or less. But if it stays on, or comes on while you’re driving, there’s a problem.

What to do if your AC thermostat is not level?

An AC unit will require the ampere setting found at the last stage of the manual’s instructions. Another problem may be that the thermostat is not level, causing the temperature gauge inside to be misaligned. Use a level to check the alignment, and adjust it if it is out of sync.
