Question about Kenmore 71121 Air Conditioner

1 Answer

Room AC, reverse cycle..heat does not work.

Our Kenmore 71121 Reverse cycle room AC stopped working on the heat cycle. Actually, the heat was used a total of two times after purchase about 2-2 1/2 years ago. One suggestion was to turn the on/off button on and off several times to see if that corrects the problem. I tried this and the heat still does not work. The suggestion was that the "reversing valve" may be stuck. Could someone tell me where the reversing valve is located?

Thanks very much.

    Same problem - different model. My is a Goodman but I have already had the repairman out once a month ago. That's when I found out why it was blowing cold air in the winter. I wonder if he just banged on the valve vs replacing it. Regardless I have a call in to him now - just waiting and freezing. I would like to know where the valve is next time this happens - it wont cost me an arm and leg.

If it is a Heat pump style the rev valve is in the Freon lines you will have to pull the unit out into the room out of it's sleeve which will stay in the wall ....it rev the flow of refrigerant is it cooling ok?? there is a solenoid on that valve that may be bad i would check that first you will have to look to see if it is energized in the heat or cool mode first to make sure it is switching it should look like a sideways tube with 3 outlets on one side and 1 inlet on the top and the solenoid coil as well with 2 wires going to it let me know what you find out ...1 Note the unit may have electric heat and the element maybe out you will have to pull to check

I have a Bonaire split aircondition & heating system. When I use remote controll change mode doesn't work heating mode. Other mode are working properly but heating mode doesn't work.


check the ambient temperature as there is most probably a lock out feature that will not allow reverse cycle to work if the system cannot remove the cold from the evaporator
To understand the system , when in cool mode the outside unit is called the condenser and in effect removes the heat trapped by the evaporating gas in the evaporator to the atmosphere
in the heating mode the roles of the evaporator and the condenser are reversed so that the evaporation of the gas in the now evaporator out side is now compressed in the inside unit and the heat from that compression action is released into the room
read the manual for the unit or talk to an ac specialist and have it explained

When set to heat it blows out cool air.


Chances are your portable unit is a reverse cycle unit...If so, the leaving air temp in heating mode is not usually much warmer than room temp with 85 degrees F just about the maximum under PERFECT design conditions. A small portable in a large cold room may only be discharging 75 degree air, which is going to feel cold.

If your unit is NOT a reverse cycle unit, the heating source (probably electric resistance) is either not coming on at all or a portion of it is not coming on due to a defective element, burnt wire or a control issue.

Why did my ac quiet blowng heat


Check the controls, this unit most likely a reverse cycle air conditioner. It can be set to cooling or to heating. The conpressor is reversed to heat or running normally to cool.
If it is not then the compressor is not working and it is just blowing room temperature air.

Not cooling 110 sq ft room


The smallest retail AC unit will cool down a 110 sqft room if...
1. It is installed in a way as to dump heat outside... 2. There is actually cool air coming out of the AC (it is working)... 3. The windows and doors are tightly closed... 4. There are no major drafty leak issues (i.e. hole in a wall)... 5. You're not adding substantial heat energy into the room (such as having 10 sweaty fat men eating food while watching Super Bowl on a 56" LCD TV)... 6. The room has at least minimum insulation (the walls are not just plywood)... Seriously, if HEAT is leaving the room by way of the AC, the room temperature HAS to decrease, unless HEAT is being added back into the room in some way. This is basically the 1st law of thermodynamics.

Fan does not reverse. the wireless remote does not have a button to reverse the fan nor the chain pulls cause the fan to reverse direction. is there such a thing as technical support for hampton fans ?


Only the remote decides when the fan reverses. Weird, I know. Depending on room temperature and selected temperature (on the remote), the fan will reverse direction. For example: If you set the remote temperature (set temp.) for 74 degrees and the actual room temperature is 70, the fan will reverse to bring the warmer air (which is always closer to the ceiling) down and warm the room until the set temperature is reached, then the fan turns itself off. The remote monitors room temp and selected settings and repeats the cycle.

How long will my AC work for, if placed inside the room


I assume that we are talking about a "window" unit. No, you cannot just place it in the room. The machine is actually two parts; one part delivers the cool air to you, the other part ejects the heat out of your house. If you just had the whole unit inside, the room wuold actually get warmer, not cooler. The reason for this is that the compressor and motor generate heat also. The "heat of compression" generated has to be ejected from the room in order for the air conditioner to work. Put it in the window.
Best regards, --W/D--

Ruud Heat Pump blows room temp on Heat and AC setting


A "Heat-Pump" is also known as a reverse cycle air conditioner, this means on heat the outdoor unit acts like the indoor section and vice versa. So in all probability you need to have it leak checked and recharged.

Reverse unit. Heater only blows air, not warm air


If you have a reverse cycle unit (heat pump) your compressor and your fan should be running. You need to determine if your compressor is running.
