Soleus Heat/Air/Dehumidfer Unit

I cannot get my Soleus LX-140 to turn on. I plug it into the socket and can get the timer to come on and off but cannot get the air/heat to come on. I have contacted Soleus and they tell me I will have to send it back to the company. I wonder if there is someone other than Soleus who can repair my unit. Soleus told me that Sears might be able to help but I called Sears and they cannot. Do you have any suggestions?

Re: Soleus Heat/Air/Dehumidfer Unit

I have had a soleus wall unit since 2005.
It is a wall unit in my apt...I have never had to use the heating part...but use the cooler part alot.
I can not figure out if that lil raindropis for adding moisture to a room...or is it to remove moisture from the room?

My apt always has to much humidity, so I do use that setting quite often, but can't tell any difference in the humidity gage.

Who knows anything about using one of these.

Is a soleus lx-140 portable air conditioner good?

If it's a real good price, and you have enough technical skill to perform the much needed & required regular maintenance for operating (especially in dusty locations) or know someone capable of said task then I say it's worth it as a menopausal woman with constantly changing internal temperature. I bought mine refurbished from (link below).

If you're not technically savvy then they may have a different model for you, but I did my research. They definitely have the best prices for appliances.

Have a Soleus LX-140 portable air conditioner. Water was leaking out the right side of the machine. Opened the casing and found a clear hose, one end attached to the plastic tray above the condenser and...

I have an LX-100, and had the same problem, so I am guessing that the designs are similar. There should be a pump in the condensate pan at the bottom of the unit -- on mine, it was near the front, right next to the overflow float switch. There should be an outlet on top of the pump, which is where the hose needs to be attached.

It looks like the pump pushes condensate up into that plastic tray, which lets if flow over the heat exchanger, both cooling it and evaporating the water. With the hose detached, you're probably noticing degraded cooling performance and a lot more condensate in the holding tank than there should be. At least, that was the case for me. Good luck.

Cannot turn on.

Since you have power to the clock display- there is power to the unit. The "power" function button has failed because the momentary switch on the circuit board below the touch pad has failed. These little push switches have a short service life.
I suggest checking a source who sells the control circuit board for Soleus Air LX-140. Might be similiar component.

Soleus 14000 btu air 12000 btu heat

Your text "will not blow out" indicates lack of air flow.
There are two posiblilities:
The upper blower wheel has failed (evaporator coil) OR the lower blower wheel has disintegrated (condenser coil in cooling mode) - which is very common on this Soleus Air model. The blower motors are very good and rarely fail.
Unplug from outlet, remove the six phillips head screws which secure the back to front of the appliance. Look for many broken pieces of your blower wheel.The proceed to and order a blower wheel replacement kit(s).
Problem solved!

Soleus air heat pump soleus lx 140 quit working

The Soleus Air condenser blower wheel is all plastic and I have seen many of them disintegrate from normal residential use. It's just a weak part.
Go to and buy a metal blower wheel replacement kit. Problem solved!
