Need to know if indoor unit fan shuts off at desired temperature

I'm wanting to know if the fan on the indoor unit of my msh12tn shuts off when the set room temperature is reached. I will not be using my studio for 3 months but would like to keep it free from mildew while I'm away. What can be done to achieve this objective?

The MSZA12NA does not shut off when the set room temperature is reached. With your unit set to cooling only, push up the temperature to 90 degrees when it is 75 in the room and see if your fan has shut off. If not, get yourself a window unit with an energy saving feature that will turn off the fan for the 3 months while you are gone.

Check your operating instructions and see if indoor fan unit has an "auto" feature that allows the fan to run only when the outdoor unit is running. Allowing the indoor fan to run constantly will provide for better air circulation and less stagnation but will use more energy.

IT WORKS BUT AT THE CYCLE END SUPPLY COLD AIR IS IT NORMAL?


Most air cons now have temperature sensors all over the machine. When it reaches temp on heat cycle, the machine usually shuts down both indoor and outdoor units but the indoor unit will keep running for a few minutes with the fan on only to cool the indoor unit down. This prevents the unit reading the wrong temperature. It stops the sensor(s) reading the heat from the indoor unit rather than the heat in the air in the room.

Make sure the indoor filters are clean. The outside unit will continue to run until the indoor reaches the temperature you have selected. Dirty filters can throw the temperature out. Its common for outdoor units to freeze up when on heating mode if the ambient air temperature is below 5 degrees Celcius.. The machine should however, defrost itself. There could be a problem with one of the pipe or air sensors on the outdoor unit.

Heil epm36f19a1 runs but no heat


Fan relay is stuck among other things. The thermostat turns on the combustion air fan and puts power to the spark unit. If the burner comes on after the temperature in the heat exchanger rises the indoor fan will then come on. After the thermostat comes to temperature the power to the gas valve which shuts off the burner. Then after the heat exchanger cools a bit the indoor fan will stop. That's the sequence of events. look at the switches that control the fans. There is a wiring diagram somewhere on one of the panels that access the unit for service.

In Fan mode, fan works; but in AC mode, I can hear the normal AC sounds, except the fan never turns on. This is the fan in the lower half of the unit in the inside of the house, which blows the air...


on a call for air conditioning your therrmastat brings the indoor fan on and the out door unit at the same time. Since your fan comes on in "fan" mode, it sounds like you need a thermastat. For temp. cooling just turn your fan switch to "on" and turn system switch to cool and set desired temp. System will cycle off and on but fan will not shut off until fan control is set back to "auto". I suggest replaceing thermastat

My AC unit will not come on even after I adjust the temperature on the thermostat


I'm assuming that this isn't a window unit. Correct me if this is not the case. Take the fan switch from auto to run. The indoor fan should come on regardless of the temperature setting. If it doesn't then the transformer could possibly be bad. Before you change any parts though, make sure the circuit breaker for the indoor unit is on. Let me know what you find and I can give you some more things to check.

If you can not control the fan speed with the control,there is fan sensior on the coil to speed up and slow down fan with the temp of the coil. You will have to call a service tech to replace. Get a free quote first Rus

Aou18c1 not shutting off


Fujitsu, Mitsubishi, Sanyo mini-split indoor fan motors operate continuoulsy. The room-temperature sensor is inside the unit, so the fan motor needs to circulate air continuouly to sense room-air temperature. This is normal operation.

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

Regarding gas pressure


ok lets see how i can help you. If the units low on gas, suspect a refrigerant leak!! 2nd, what refrigerant it's using? I can't tell you operating pressures if you don't know the refrigerant. (usually the label on the indoor unit right side says refrigerant charge and type.) 3rd desired temperature for cooling is about 68-72 F that's about 20-22 Celsius.

id keep it on 21 C
