After i press temperature and humidity; which i don't have a manual because it was for my grandmother, and she doesn't know where the manual is. I'd like to know exactly what is that I am doing wrong. What should I be doing first. model# m7dh45b2a

Humidity is said to be good at 50% RH and temerature at 77*F. Air looses humidity when it is heated or cooled. Extremely humid conditionals it difficult for air conditioners to cool the air.
The temperature to be comfortable in varies from person to person.
No, it may mean that you don't have the humidity extraction level set low enough. The lower the setting, the more humidity it will extract. Try setting the extraction level at 35%, to see if the compressor turns ON.
If yours is being used in a basement, the ambient air temperature at floor level is between 40 - 60 degrees. Dehumidifiers do not work well between those temperatures (Unless, you have a Low Temp Unit). This applies mainly to where the air
temperature at floor level is colder than at shoulder level in basement applications. Raising the unit up off the floor, onto a sturdy table, counter top, etc, that can handle the weight of the unit, plus a full tank of water, will usually resolve this problem.
I hope this helps you further troubleshoot & solve the problem. Thanks for choosing FixYa.
Don, unless your dehumidifier is a Low temperature model, that very well may be the problem. The air temp in a basement at floor level is colder than that chest level. Dehumidifiers don't work well at temperatures at 40 degrees F or less. Raising the unit up off the floor on to a sturdy table, counter top, etc, that is strong enough to handle it's weight, plus a full tank of water, will generally solve the problem. The higher up you can safely put it, the better. Also, lower the humidity extraction level to 35%. As 50% is just not low enough in a basement application.
Set the temp level at whatever point your home's temperature is now. Lower the humidity level to 35%. If you don't have an LED screen on your unit, set the manual control to maximum.This way, you will extract the maximum amount of humidity and make your home more comfortable.
If the unit shut off automatically, because it had reached the humidity extraction level you had it set on. It won't turn back ON again, until the humidity level rises above the setting you have it on. Lowering the humidity extraction level to 32 -35%, should make it start up again and cycle like it should. If your unit does not have an LED Screen, set the manual control on Maximum.Be sure the bucket is not full and the air intake filter is clean.
Hope this helped you to troubleshoot and solve the problem.
derkfarm - It may simply be a case of the humidity extraction level being set to high and/or the air intake filter needs to be removed and cleaned.
Solution: Lower the humidity extraction level to 32 - 35% and clean the air filter.
If the unit is in a basement, the ambient air temperature at floor level is colder than at chest level. Dehumidifiers don't work well at temperatures between 40 - 60 degrees F.
Solution: Set the unit up off the floor on a sturdy table, cabinet, counter top, etc. It must be sturdy enough to handle the weight of the unit, plus a full tank of water and the vibration, while in operation.
Any or all the simple solutions above may solve the problem. But, we won't know, until you try them.
Please let me know if it helped or didn't solve the problem. Thanks.
You may have the humidity/moisture level set to high. Try lowering it to 35%. Or if you don't have a LED Screen on your unit, turn it to maximum.
In addition, most dehumidifiers don't work well if the air temperature is between 40 & 60 degrees F. Keep in mind, the temperature at floor level in a basement is colder that the air temperature at chest high level. Raising the unit up, off the floor on something sturdy enough to handle the weight (with a full tank of water) and the vibration, may help.
Hope this helps you to troubleshoot and solve the problem. Please let me know. Thanks.
Rather than have you disassemble the cabinet to get to the coils, I want you to do an "At Home Test".
Move the dehumidifier to a bathroom that has a shower. Plug it in, Turn it ON and set the humidity level at 30%. Turn the shower on to medium hot (enough to generate some steam. Do Not turn On the bathroom exhaust fan. As you leave the bathroom close the door. Wait 15 minutes and return to the bathroom. Turn the shower OFF and inspect the unit's water collection bucket for water. If you find any, the unit is working as it should. If you don't find any water, it may be that the humidity sensor has failed or the air intake filter is clogged. In which case, remove the filter and clean it. If it's the sensor, unless you are really DIY savy, I'd recommend buying a new dehumidifier. As finding the part (your unit was made by Fedders), the cost of the part and the labor involved, to me, out ways repairing it.
Now, on the positive side ... If you saw water in the bucket after the bathroom test. It may simply be, that at this time, there is not enough humidity in the room air (even at 30%) to trigger the sensor. If the unit is in a basement, the air temp (60 degrees or lower) will affect it. As the temperature at floor level (where the unit is) is 5 to 8 degrees colder than the air temperature. Dehumidifiers don't work well in cold temperatures.
Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.
SETTING THE MACHINE TO TURN ON 1. Make sure the dehumidifier is plugged in but turned off. 2. Press the button with the clock symbol below it. 3. Press the up arrow to set how many hours until you want the machine to turn ON. If you have pressed the button for more hours than you wanted then press the down arrow to lower the number of hours. 4. After you have stopped pressing the arrow buttons the display will return to the original display showing temperature and relative humidity. 5. After the above steps are completed the dehumidifier will turn ON in the number of hours that you have set (programmed).
SETTING THE MACHINE TO TURN OFF 1. Make sure the dehumidifier is plugged in and running. You should hear the fan blowing for sure. 2. Press the button with the clock symbol below it. 3. Press the up
arrow to set how many hours until you want the machine to turn OFF. If
you have pressed the button for more hours than you wanted then press
the down arrow to lower the number of hours. 4. After you have

Pressure and temperature is directly related with refrigerants in the system. Ice building on part of the coils shows that the pressure inside the system is low and the system has lost some of its charge. Very low humidity with a low ambient temperature will also cause such a problem.
