Question about Heating & Cooling

1 Answer

Unit works great on heat, but when set to cool the temperature display increases when it is actually cooling down. If i unplug the thermostat from the wall for a few minutes and plug it back in, it will sometimes reset itself to the correct temp, which is usually 6 to 10 degrees cooler than the original reading. Display also blinks "cool on" sometimes for several minutes before coming on.

Hi,
I would change the thermostat... it is running the heat anticipator in cooling when it should only run it in heating...
The heat anticipator is like a small heater inside the thermostat that fakes the thermostat into shutting down before the temperature is actually that warm so that the residual heat from the furnace just heats the room to the proper temp.
Pulling it off the wall temporarily fixes it but then it hangs up again later...
The flashing also is very normal....that means that the thermostat is in delay mode.....it will do that to let the pressures equalize in the A/C condenser so that it will start properly...nothing wrong there...
Make sure to mark each wire well before taking the old t-stat off of the wall...also make sure to read the directions and get the new stat set up properly for it to work correctly with your system.

White-rodgers 1f80-261 thermostat: Set to heat, "flame icon" appears but no heat and no fan. Thermo doesn't click when adjusting temperature. Set to fan,there is no fan.?


There is a 3 amp fuse in the main circuit board. If this fuse is bad ,nothing will work but because of the batteries in the thermostat it will lead you to believe that the unit is working properly,however, it is only showing you what is supposed to be. Replace the fuse and everything will work.

Air Conditioners Cooling Tips


  • Whole-house fans help cool your home by pulling cool air through the house and exhausting warm air through the attic.
  • Set your thermostat as high as comfortably possible in the summer. The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
  • Avoid setting your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
  • Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing your power use.
  • Avoid placing lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
  • Plant trees or shrubs to shade air conditioning units but not to block the airflow. Place your room air conditioner on the north side of the house. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun.

    hi,
    Wine cabinets work off of cycle defrost, so in order to built frost your temperature sensors are not working properly. I would look for corrosion on or in connections to be the fault or problem. Sensors report information to control unit and thats there only job. Its the control unit that dictates function. Look for corrosion to be the problem, clean connection and seal with RTV when connection a corrected.
    Good Luck

    Frigidare window air conditioner with remote control about 3 yrs old. All controls seem to be working except when the energy saver mode is suppose to shut down the unit / the display goes dark but the...


    Hello, I can assist you.

    If the unit is supposed to turn off and it doesn't, it will be necessary to check several things.


    • First, is the unit cooling properly? See the section entitled "The air is cool but doesn't seem cold enough."

    • Next, is the temperature of the room adequately cool? If the room temperature is cold enough try setting the thermostat to a higher temperature. If the unit then seems to work properly leave the thermostat set to the higher temperature.

    • If the unit is cooling properly when it is turned on and the room is not cool enough the problem is probably that the unit is trying to cool an area that is too large for its capacity. Use the following chart to find the appropriate size air conditioner to use:

    AREA TO BE COOLED / CAPACITY (BTU/HR)

    100 to 150 square feet = 5,000

    150 to 250 square feet = 6,000

    250 to 300 square feet = 7,000

    300 to 350 square feet = 8,000

    350 to 400 square feet = 9,000

    400 to 450 square feet = 10,000

    450 to 550 square feet = 12,000

    550 to 700 square feet = 14,000

    700 to 1000 square feet = 18,000

    If the room is heavily shaded, reduce needed capacity by 10%

    If the room receives a lot of direct sun, increase needed capacity by 10%

    Add 600 Btu/Hr for each person in the room if there are more than two people

    If the unit is for a kitchen, increase the capacity by 4,000-6,000 Btu/Hr.

    If the room size is too big for the air conditioner you have two possible choices. Either decrease the room size by shutting some doors or partitioning off an area of the room. Or, increase the BTU of the air conditioner for that room by installing a different air conditioner with a higher BTU rating.

    the unit runs all the time because of the fan (ventilation motor)-but it is not working on cooling or heating all the time - The ventilation motor pushes the air from the room through the machine and when the termostat is reading that you set it up for cooler air or warm air it will turn on the air conditioning part or the heating part of the machine-it is very good system actually

    Tip

    Becoming more efficient with your heating and cooling


    Here are some ways to become more efficient with your heating and cooling. Obviously you do not have to do them in order but try to complete as many as you can! = )
    · Buy a laser thermometer! You can use this to detect air leaks (or at least areas with “minor” temperature differences) so you know where to put seals
    · Keep blinds shut on hot days and open on cold days----helps reduce temperature extremities
    · If the temperature is can be negated by using a t-shirt or a jacket, use that clothing! You will save temperature control costs and still be able to keep warm or cool
    · Do not use those old lightbulbs on hot days---they make extra heat increasing cooling bills (but you can use them on cold days to help warm your house)
    · Utilize energy star products to increase efficiency comfortably
    · Set your thermostat as low as is comfortable in the winter and as high as is comfortable in the summer.
    · If you are on vacation, turn of that air conditioning/heating! No one will be in the house if everyone is away and it shouldn’t be too uncomfortable to wait like one hour for the house to cool/heat
    · Don’t turn your thermostat up/down just to heat/cool faster---all temperature control changes the house temp at the same rate and if you forget to turn it off, you just wasted some energy there!
    · Don’t block heating/cooling vents so that your rooms can be controlled quickly and so that your air actually gets controlled, not your furniture
    · Check up your air conditioning and heating systems regularly (not once a month but maybe once every year) so that the systems stay running the best they can
