I have an lg dehumidifier LHD 45EL. The humidity reading reads 15% higher than a stand alone humidistat and the unit will go on for a short time even though the set humidity level is 70%. What gives?


Possibly the primary humidity sensor behind right side grill. Unit MUST be unplugged from outlet. Take right side grill out, unplug sensor from wire socket and plug back. If no help, you need new sensor.

LG LHD45EL


The temperature sensor on teh suction return line from the coil has drifted out of spec and needs to be replaced. This sensor is part of the sensor assembly which plugs into the control board. I purchased the part from Appliance Factory Parts on line, cost about $30, an hour or 2 to change depending on your mechanical level, it is easy to do. For Goldstar DH404E part # was 6877A30013M, they are same part for many models but if this is not the right # for your model just get the right "sensor assembly" for your model and change it out. It consists of Temp/humidy sensor in coil, temp sensor in suction return line, and plug harness that goes to float switch. My uni is running like new again.

Red full light blinks, humidity level stays at 01, runs for one second or not at all.


I just now noticed this posting even though it is now November. I will post this in case you still have the dehumidifier & haven't solved the problem yet, or for those who may be searching for a solution later.

The 01 code & the blinking light indicates that the defrost sensor is probably shorted. Replace the sensor assembly with part #6877A30013L. It includes the humidity sensor & defrost thermistor & plugs onto the main circuit board for an easy repair. Sears lists it on their website for 9.99 + shipping.

Dehumidifier Error?


This error code indicates that the problem is most likely a shorted defrost thermistor or possibly a pinched wire going to the thermistor. You will need to replace the sensor assembly - part # 6877A30013L. The Sears website has it listed for 9.99 + shipping. The humidity sensor & defrost thermistor come together in a wiring harness that plugs onto the main circuit board. It is fairly simple to repair. Just remove the front & rear grill & the metal cabinet. Remove the thermistor from the copper tube on the cooling lines; remove the humidity sensor from the front of the evaporator; pull the wire plug off the bucket switch; & remove the small 7 pin plug from the main circuit board inside the metal control box. Reverse procedure to install new sensor assembly.

Same problem with Goldstar model DH404EY7 -- stop code 01 on startup, bucket full light blinks (drains to floor).

Replaced the main controller board to fix it.

For my model dehumidifer the part # is 6871A20888A, and cost $77.44 (not counting shipping) from Appliance Factory Parts. The Appliance Factory Parts web site also provides parts breakdown (exploded parts diagram) diagrams and service manuals in PDF form.
