If it totally dies, the AC unit will not operate. If it is "failing", the unit will not maintain the proper temperatures.
When a thermostat goes bad in a vehicle, it can make your car overheat. It can also make it t where you do not have any heat inside your car.
The thermostat tells the air conditioner to pull in air. The air then goes through cooling lines in to the house. goes through the vents and out through the registers in the rooms of the house.
If it's stuck open, no heat. If it's stuck closed, over heat.
Generally speaking, a thermostat should command an air conditioner (or a furnace) to turn off once the thermometer inside the thermostat senses that the a given temperature has been reached. For example, if you have manually set your thermostat at 75 degrees, the thermostat's job from that point on is to maintain that temperature, or a temperature within one or two degrees of that. If the thermostat didn't turn the air conditioner off periodically the house would get much cooler than desired; using up a large amount of (expensive) electricity, and over burdening the air conditioner compressor, prematurely wearing it out leading to a costly repair bill. You might look at as the thermostat giving the air conditioner a rest and your wallet a break. Many, if not most thermostats also serve another role which is to safeguard the electronic startup up equipment and motor of the air conditioning unit. You might experience this when attempting to turn the air conditioner back on within a few minutes of it having turned off. This is a built in safeguard feature which protects certain delicate components inside your air conditioner from premature burnout or an electrical overload. If you experience this it's best to wait ten minutes or so for the safety system to reset. Hope this answer was helpful. ---------------------------------------------------------------------------- Thanks for the reply, but when I said it "Shuts Off" it means that the Thermostat LED goes blank, as if there is no power to the syste.
The air conditioner will create extra heat. So if it's really hot to begin with turning on the AC will only make it harder on your cars cooling system. If you haven't had your coolant flushed/thermostat changed in a long time you might want to try that. Also make sure there are no obstructions in front of the radiator.
It speeds up.
No ------------------------------------------------------------------------------------------------------- The spring side of the thermostat goes towards the engine, and if the thermostat is installed vertically the vent hole goes at the top. Helpfull
The spring side goes TOWARDS the engine , and if the thermostat has a vent hole it goes to the top if it is a vertically mounted thermostat
The spring on the thermostat goes down towards the engine.
It is possible
heater not hot
The temperature gauge on a car fluctuates because the car's thermostat is opening and closing. The gauge goes up when the thermostat closes and the gauge goes down when the thermostat opens.
