Check the contactor to see if the contacts are stuck or welded together, if not check to see if you have 24 volts to the contactor, if you do then the thermostat is not opening.

    Usually the thermostat sends the signal from Y or Y1 to the condenser. If you go to the contactor and follow each wire, one should go to one side of line or 220 called common, the other should go to either a relay,circuit board or to the thermostat. If it goes directly to the thermostat and there‘s no voltage, then it’s the thermostat that is the problem. If it goes to a relay or circuit board then you need to determine if you have voltage from the thermostat to the relay or circuit board, if you have power to the circuit board from Y or Y1, then it’s the circuit board. If you have power from Y or Y1 to the relay and it’s not closing to let the condenser come on then it’s the relay.

Using as heater and unit is blowing cold air


A heat pump is an air conditioner that reverses its refrigerant flow. In the cooling mode, the evaporator is cold to the room and its condenser is hot. In the heating mode, a valve reverses the refrigerant flow and makes the evaporator warm and the condenser cold.

Using heater...cold air out of the back


With heat pumps that's the way they work. In heat mode they are using the evaporator as the condenser and it blows heat out the front and cold out the back. In cooling mode, a reversing valve switches the gas flow reversing the operation of the coils and it blows cold out the front and heat out the back.

I have a soleus 40 - it's been running for a year but I don't think it was working. My husband looked at it and says it runs and the compressor overheads and shuts off and the fan continues to...


Several things can cause this problem.

1. The air intake filter is dirty or clogged and needs to be removed & cleaned.
2. Obstructed air space. The unit requires 12' to 18" of clear air space around the entire unit.
3. The compressor may be low on refrigerant gas and needs to be recharged. Leave this to the pros
to do,
4.If it's in a basement, it may be overheating because the temperature at floor level is colder than
at shoulder level. Dehumidifiers struggle at temperatures below 65 degrees, unless you have a
Low Temp model, designed for basement applications. Raising the unit up off the floor on to a
sturdy table or counter top that can handle the weight of the unit, plus a full bucket of water, will
generally solve the problem.

Hope this helps you to troubleshoot and solve the problem. Thanks for choosing FixYa.

Not removing water and says tank it full


I just had one giving me the somewhat the same problem. Upon taking it apart I found that the entire inside was filthy. This thing runs in a work area in my basement and sucks up all of the dirty air. When you take the water out of the dirty air you have nothing but the dirt and the water. When you mix those together you get mud which is what clogged everything up in mine.

Dehumidifiers need to be clean on the inside to run properly especially all of the fins on the condensor. You will probably have to take it apart and clean it. Concentrate on the fins and the water collection areas. Dehumidifiers remove heat from the air which causes the humidity to collect on the condensor. As it collects it turns into water droplets. Gravity pulls the water droplets into the water collection areas and that flows to your tank. There is some sort of float in your tank that lets the dehumidifier know it is full and shuts it off with some sort of switch. It does this so it does not just keep running and eventually pour water onto your floor. It sounds like your switch and/or float is stuck. Find the float and switch and manually work them to make certain they are working freely, clean if necessary.

If the dehumidifier does not remove water like it should it is probably not getting good airflow. There are ice sensors on the evaporator that tells the compressor to stop working. However the fan will still run to pull warm air across the ice so that it melts, goes into the water collection area and into your tank. Some of these ice sensors work by measuring air flow. If there is no air flow or very limited air flow the sensor will tell the compressor not to work. The fan will run again to melt the ice so that it melts and is removed. If your condensor is dirty and does not allow the air to flow, this could cause your problem.

My soleus CFM40 has stopped dehumidifying. Just blows cold air. I think the heat element that dries the air stopped working. Do yo agree?

My Soleus Dehumidifer is not dehumidifying


If the room temperature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

Top of dehumidifier is very hot to the touch, filter is clean don't know what to do, afraid to put it on in case of fire.


Are you running it in high ambient temperatures?
Can you see any condensate(water) on the coil?
It may be that it is running above it's temperature range. A dehumidifier has two coils(radiators if you like). One gets cold, the other gets hot. The first one renoves the moisture from the air, this is the evaporator and is cold. The heat taken from the air is absorbed into the refrigerant and is given back to the air when it passes through th other coil, the condensor which is hot. The refrigeration circuit itself produces heat. This heat plus the heat absorbed from the air has to be got rid of. If the ambient temperature is high, the condensor will have trouble getting rid of the heat from the circuit. This can cause the case to feel hot to the touch. Assuming you don't have a refrigeration leak, it may not be worth running the unit if it is not removing moisture from the air. Is any water being dropped into the bucket? If it isn't, all you are doing is wasting electricity.
