Why does Thermostat gauge go on and off What is wrong with it in my 1993 ford escort lx?
There could be several things wrong with the system that the thermostat gauge is connected to. You could check to see if the gauge is working correctly. If the gauge works fine, then it could be the housing that the thermostat is mounted to. It could also be a faulty bypass valve near the thermostat which prevents the engine from heating up. Check these places to see what may be wrong with your escort. ...

How do you know if you have to change the thermostat for your overheating problem fan works properly but the temp gage goes all the way up and most times comes down possible stuck thermostat in jetta?
There is no sure way to know until you take the thermostat out and check it. After removing the thermostat, you can test it by submerging it slowly, with a tool in boiling water. You can then see the thermostat open up. If it does, this is not your overheating cause. If it does not, you need to purchase a new one. Install the new one and you will find out if that was the problem. ...

Asked in Thermostats, Home & Garden
What is wrong if you have a digital thermostat in your house with zoned heat and air and the heat and air work fine on the thermostat upstairs but there is no heat on the downstairs?
There is either a problem with the downstairs thermostat, or the wiring from that thermostat to the unit. First check the batteries in the thermostat. Yes the digital ones have batteries. :-) Next, if that doesn;t fix it, try switching your two thermostats. Be careful to wire them exactly as they were before. If your heat now works downstairs and not upstairs, replace the thermostat. If the problem remains unchanged and you still have heat up and not down - check your...

Asked in Endocrine System
How is your endocrine system like the thermostat in your house?
The negative feedback system. It works much the way a thermostat works. When the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. Once the furnace has raised the temp in the room to the set level, the thermostat signals the furnace to shut off. It will continue to stay off until the thermostat signals that the temp has dropped again. ...
