    the unit seems to be running but the cool air is just not coming through and temp is not dropping, i have also removed the dust from air filter, what other info do you need

    the outdoor unit seems to be running but it does have a sound that pauses not sure if that's the compressor, does the refrigerant leak need to be checked by professional? the filter isn't that dirty since I only had it for 6 months, i'm letting the fan run for a few hours to see if there is any changes...i'm not sure how to check for the last question, its not a noisy unit so not 100% sure about how to check for compressor

    is the outdoor unit starting then stopping if so it could need to be checked for a refrigerant leak if the filter was really dirty you could get ice on the inside coil you would just set your thermostat to off and let the fan switch in the on position for a few hours. Can you tell if the compressor outside is on or just the fan this is important for troubleshooting

My panasonic air conditioner does not turn off when cooling


At what temperature is the thermostat?
The temperature should never be lower than 70?F (21?C) for the unit to operate properly. If your temperature setting is above 70?F, then your unit might have a problem with the temperature sensor that controls the "on/off" cycle on your unit. For that you will need a professional certified HVAC tech to inspect it.

Most people think that lowering the temperature to the minimum will cool the room faster, but that is not the case. Since HVAC units move the air at a specific rate, it can only transfer the temperature, thus cooling/heating the air, within those parameters. That's what the calculation for the BTU is for. Normally cooling/heating the room to the desired temperature should take about 1 hour, but some new inverter units can do it in only 30 minutes or so. Lowering the temperature constantly or even keeping it at the lowest setting may cause premature failure of the unit.

Fan comes on; however, can't get the desired temperature to set. I select it and two seconds later it shows a higher temperature.


Hi Kate, When you press the button for your desired temperatre setting it will show this temp' say 17*c for a few seconds then it will revert back to showing the actual room temp' say 23*c, it should then cool the room down to what you set it at. hope this helps.

Let see if I can help. The numbers don't come up so we'll just try your information.

Thermostat keeps jumping back to 85 when i set it to desired cooling temperature


Make sure you are not reading room temp. for starters, the other solution is to reprogram the thermostat in both heating and cooling mode

When I cool the room it doesn't drop to the temperature I have it set to but a few degrees celcius higher. Is that normal? I honestly never checked on my old unit but this one doesn't seem to feel as cool.


there is suppose to be 15--20* temp. different on the air supply & return air temp.Over 20* and the coil or the filter is plugged up. Below 13*--anf the unit is not charged properly.

Housesitting. RTH111B model. I cannot keep the


That is a NONprogramable T-stat. There is no program to overide, therefore there is no need for a "hold" option. To set the temp, place the switch on the side marked

COOL
OFF
HEAT

to the desired setting, and push the up down arrows on the front until the display shows 80.

The DISPLAY will revert back to the current room temperature within a few seconds, and will keep the unit on until it reaches the desired temp.

The set temperature remains at 80, it just shows the current room temp.

Lg split indoor fan runs non stop


Hello Hamid,
The unit is designed to run the indoor fanmotors continuously when in cooling mode on both indoor units (evaporators). The reason is that this circulates the air and the temperature thermistor or sensor is able to sense return air temperature and in turn start or stop the outdoor unit and compressor as required according to the setpoint temperature. The reason for either unit not reaching setpoint temperature can be a couple of reasons. A) Incorrect design - the unit may be too small for the application. You can calculate this roughly at 650BTU per square meter of room in a relatively warm ambient climate. Or secondly B) The outdoor unit has leaked and is short of refrigerant. You can check this when the outdoor unit is running by feeling the thicker copper tube on the right hand side of the unit. This should be cool to cold. If no temperature difference is felt, it is short of refrigerant. Hope this helps you. Goodbye
