AC WILL NOT SHUT OFF

MY LG AC UNIT CONTINUES TO RUN EVEN AFTER IT REACHES THE PRESET TEMPERATURE. THE UNIT IS ABOUT 9 MONTHS OLD.

    I have the same problem, heating only. When the tstat reads 72 it clicks (a relay drops or picks up) but the inside and outside units continue to run, forever. The outside unit starts sounding like it's leaking freon, it isn't, it's just in an odd mode. I've changed the tstat for a different reason, same problem occuring. Back in the summer my ac guy came out and did a yearly for me. I think he moved one of the wires on the tstat. I put the same wires on the same lugs for the new stat, so I'm thinking this is a problem with the wiring. I have a Train.

SOUNDS LIKE THE T-STAT TEMPERATURE SENSING BULB IS OUT OF "AIR-FLOW" (SOME CAN COME LOOSE FROM THEIR MOUNTING CLIPS) OR IT IS BAD ALL TOGETHER ... MOST MANUFACTURERS HAVE A ONE-YEAR WARRANTY ON SMALL PARTS AND 5 YEARS ON THE COMPRESSOR .., HOPE IT HELPED.

When I turn the engine off the engine cooling fan stays on and does not shut off


depending on the engine temperature the fan is supposed to remain on after you turn the engine off, until the engine reaches a preset cooler temperature. when it reaches cooler temperature usually within 5 minutes or so it should cut off... if you cut it off and it is running 30 minutes later.. then there is a problem with the fan relay or temperature sending unit.

My heay surge stove will run for awhile and then shut down


The heater is thermostatically controlled, so once the room temperatures reaches the heater's preset temperature, the heater cycles off. This is normal.

However, If the heater goes off BEFORE the room reaches the preset temperature, suspect a high temperature safety switch that may be tripping. Does the heater come back on after it cools down?

After my air conditioner is on for awhile it will automatically shut off completely then after a few minutes it comes back on. It is not set on the energy saver setting. Also it is and continues to do...


Debi, it;s not unusual for an AC unit to turn ON & OFF. Once it reaches the temperature that you have it set ON and holds the temperature for 4 or 5 minutes, it will shut OFF until the room temperature rises above it. Be sure all the doors and windows are closed and no hot air is infiltrating the area.

Also, a 10,000 BTU air conditioner is not designed to handle a large area. Generally, 10,000 BTU's will handle about 3200 Cubic Feet (20' x 20' x 8' = 3200 sq ft) or simply put, 400 square feet. Your A/C unit may be undersized for the area you're trying to cool.

Hope this helped you. Please let me know. Thanks.

At what temperture should you turn it to aux heat and why does my furnace run for hours


It should switch to the aux heat automatically, when it reaches a preset temperature. Usually, when the outside temperature reaches 32 degrees, if it's a heat pump furnace. It can bet preset a little higher though, depending on the unit. If it's extremely cold outside (in the low teens) It may run a lot longer just to keep up. Especially, if you home is not energy efficient.

If your's is not switching over automatically, the sensor switch on the heat pump may have gone pad or the aux heating strips my not be working at all. This requires the service of qualified heat pump service person..

How do I set the heat at 75 with no fan mode. I don't want the fan to come on once the room reaches 75


Hi, there is no way that this can be done. The fan is controlled by several different parts for the furnace to run properly. If you are saying that the fan continues to run after it reaches its set point, this is normal if it only runs for about a minute and 1/2. This is to cool down the heat exchanger. If it continues to run all the time after reaching its 75 degree set-point, you have a fan relay that is sticking internally, or a high limit switch that has failed and depending on how old the unit is, it may be what is called a combination fan/limit control that has dirty or burned contacts which will keep the fan on. What I am trying to say, is when your unit reaches the temperature you want, the fan should only run a short time as the limit controls are there to shut it down from a setting on the fan control that is preset by the factory. If you can give me more information on your unit such as model, serial, name of unit, and if it is a gas fired central heat and air unit, or heat only, a heat-pump ect. would be of a big help to determine what controls you have on this unit that is keeping the fan on. Leave this info in the comment thread for my user name, and I will get back to you.

I have model # crgr7900A31 gas dryer front end loading. The dryer will not shut off. It continues to run.


Hi, If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.
Normally, this is what happens during an automatic cycle: The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees. When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.) The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again. This cycle continues until the clothes are dry. But if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.
