Why would thermostat temperature never move up yet shut off and cycle when furnace heat goes on?

Most digital programmable stats nowadays have algorithms configured to start & stop a furnace or ac unit within a degree of the display temp, say .5 or .6 of a degree to maintain close control of the space. You may be able to spread the cycling out a bit by going into the stat`s configuration menu and looking for CPH or cycles per hour and reducing that value to 2 or 3.

Could your thermostat cause you not to have heat?
Certainly. If the engine coolant is flowing freely into the radiator, it will remain quite cool and the coolant that circulates into the heater core will never warm up. The thermostat blocks the coolant from entering into the radiator if the temperature is below the set level on the thermostat. Usually 185, or 195 degrees F. Engines don't run as efficiently at the lower temperature either, so if the thermostat isn't working right, replace it.
What falls but never hit the ground?
The temperature.
Heat flows from what temperature to what temperature?
High temperature always flows to low temperature, never the other way around.
What causes the evaporator to freeze?
The evaporator may be dirty or the condenser(outside unit) may be dirty. You may be low on "freon", indicates a possible leak. Check the filter. ---------------------------------------------------------------------------------------------------- If you're asking why the 'outdoor' part freezes, it's too cool outdoors. You should never run a house central A/C when the outdoor temperature is below 60 degrees F. Professionals will tell you that you can blow out a compressor this way. Big $$$$. You may be asking why there's a part in your furnace (that has part of the central A/C inside) that freezes over with ice in the summer. Your first clue will be that the house gradually grows very warm even though the A/C is running, and it worked fine until now. If the indoor air is too hot and damp when you turn on the A/C, you can overwhelm the system's ability to move heat out of your home. Instead of collecting moisture at the heat exchanger inside your furnace and using gravity or a small pump to move the water to a drain or outdoors, the water freezes right on the heat exchanger. The ice acts as an insulator, continues to build and the house will remain warm. This can cause expensive damage as the ice grows too big for the area around it. Switch the thermostat to heat (furnace) instead of cool and raise the temperature setting for about 5 minutes and the ice should all melt, then you can switch back to cooling. Since you've already removed much of the moisture in the house, you'll probably be fine, and the few minutes the furnace was running won't even be noticed.

At what temperature does Lithium-6 emit radiation?
Any material will emit blackbody radiation at any temperature. Lithium 6 will never emit ionizing radiation.
How do you know if the thermostat went out in a Chrysler lebaron?
If the thermostat is stuck open, the engine will never warm up to proper temperature.
How do you install heating thermostat only for furnace?
I am assuming that by asking about a "heating thermostat" for a "furnace" we are not talking about air conditioning/heating units or about electric heating units (baseboard, wall-mounted, etc.). If the furnace already has a thermostat installed then it is just a matter of replacing the existing thermostat with a new one. Heat-only thermostats can be obtained from home centers such as Lowes or Home Depot. They should be specified to work on 24-volt circuits, unlike those designed for 110/220 volt AC electric heaters. Replacement is simply a matter of removing the thermostat cover, detatching it from the wall, and disconnecting the two wires from the old unit. Connect the wires to the new thermostat and mount it to the wall in place of the old one. Be aware that some thermostats must be adjusted level to work properly - read the enclosed literature that comes with the new unit. If this is a new or replacement furnace that has never had a thermostat connected then there are several additional considerations. You will need to identify a location for the thermostat. This location should be on an interior wall, out of any drafts, and in a location such as a hallway which is an "average" of surrounding rooms. You will have to run 2-conductor thermostat wire (available at home centers) from the furnace to the thermostat. Connections to the thermostat are as outlined above. The connections at the furnace end depend on the type of furnace - passive hot air, forced hot air, passive hot water, circulator-driven hot water, steam, etc. These variations are beyond the scope of this general question.
What does a car thermostat do?
The thermostat is a device which blocks the flow of coolant through the radiator until the coolant inside the engine reaches a certain temperature, at which point the thermostat gradually opens to allow enough coolant though to maintain the engine at its optimum operating temperature. The thermostat then controls the flow of coolant to keep the engine at that temperature irrespective of engine load and operating conditions. Without a thermostat and engine warms up more slowly and will never reach its optimum temperature. This causes increased fuel consumption and increased wear on the moving parts.

The thermostat also make the heater work much quicker in winter
Do you need a thermostat on a 95 Honda Civic dx?
Yes, you most certainly do. If you have no thermostat installed then the engine will take a very long time to reach full operating temperature and may never get to the proper temperature. The thermostat allows the engine to warm up quickly which helps prevent engine wear, reduce engine deposits, and emissions. The thermostat keeps the engine at the proper operating temperature for the best performance and best mileage. Running a modern computer controlled engine without a thermostat is a very bad idea.
Why does your 1995 Buick Regal temperature gauge never goes above 170?
The thermostat is probably set for 190 degrees and that is the point it opens at.
What causes a 1999 Ford Expedition never to heat up?
Could be a bad thermostat - not closing allow water temperature to reach 195
Is furnace penitentiary a real place?
No, Furnace is not a real place. the government would never allow it to open.
Is radiant floor heating controlled with a thermostat ?
Yes, radiant floor heating is controlled by a thermostat. This is important as it makes sure the temperature never gets higher than you want it and that when it gets cold the heating goes on automatically.

Can you run a 1996 Honda accord without a thermostat?
Can? Yes, but should you? No. The thermostat is an integral part of the cooling & emissions system. The thermostat allows the engine to reach optimum operating temperature very quickly which is a good thing. Without a thermostat the engine will take much too long to reach this temperature and in fact it may never reach it's correct operating temperature. Engines run poorly when cold. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions. The engine will get better mileage and last much longer. Install the correct thermostat and forget about leaving it out. There is no good reason to run an engine without a thermostat.
Can you drive without thermostat?
Yes but, the engine will never reach operating temperature. Many of the thermoswitches won't function until the engine reaches operating temperature and also the heater will blow only warm air.
