You'll have to remove the sensor with wires attached. When sensor is warm you will have continuity (need a circuit tester of some type). Put the sensor in your freezer for about 15 minutes. The relay in the sensor should open and there will be no continuity. If there is continuity after removing from freezer, sensor is defective.

, My KM30 Dehumidifier t'stat will not reognise ambient humidity properly. I placed the unit in my boat-steamy 80% humidity at 50%. it consistently turned itself off. Ok on 35 and Lo.

there is a sensor in the unit much like a temp sensor, (bullet shape) over time these do ware out and need to be replaced this tell the unit the temp so the unit knows humidity. it could also just need cleaning as a build up of damp then dry dust can cover the sensor.

Our FDF50S Dehumidifier keeps showing AS or ES. We tried to hook an hose to the drain outlet and it never worked. So what is wrong with the dehumidifer?

AS or ES is fault code for Humidity Sensor Failure. Contact Frigidaire Technical Service at
800-944-9044 for assistance. This part may be warranted for 2-5 years from date of purchase. You must have a Proof of Purchase for a warranty claim. If nothing else, they can tell you which sensor needs to be replaced and supply the part at your expense.

Hope this helped steer you in the right direction.

Furnace kicks on but the gas stays on for about 6 seconds and then shuts off and repeats this two more times and then stays off for 20 minutes and then starts all over again

This tells me that its either an ignitor or flame sensor. You will need to check to see if the ignitor is working by watching it when the unit comes on and if its not then replace the control board for the ignitor or the ignitor itself. If it is coming on then its the flame sensor. Sounds like the ignitor though. I would check that. These go back on a reg. basis.
Feedback is apprec. Thanks.

What does an E3 error code mean on a Delonghi DE500pc dehumidifier

Condensation sensor was tripped...needs to be dried/cleaned/repaired (on lint screen side remove plastic panel. The sensor is clipped to radiator fins.

Be Safe or don't do it....

On the side with the lint screen, remove the five screws holding the top panel in place. The sensor that needs to be checked in mounted on the radiator fins. Remove the sensor and 4 pin connector. With a pin, remove the loose fitting housing the "sensor"...a circuit board that "shorts" with condensation...check corrosion and look for component damage on the oft chance the circuit board was damaged by some inappropriate poking or mechanical failure. Reassemble and replace sensor...

For a short life span...or out of warranty and only at your risk (IF have significant other or kids or pets or human DNA... don't do this...) .. guide wire through screen notch and attach to outer screen. Build fortress around exposed sensor and talk to insurance agent for a special rider...seriously be careful.

Did you? Clean screen and GENTLY clean fins of lint, etc....(vacuum's brush head should do the trick...)

Taking all appropriate safety precautions.


Here's the 100,000 (yen) tip....with humidifier unplugged, hold down the power button (green button in lower center) and plug in the appliance.

Watch the LCD screen as it conducts a self test...and wha...lah!.

Our delonghi de400p dehumidifier shows an E3 error message. Customer Service says its a sensor but can't tell us what sensor. Any help would be appreciated.

I have a 40 pint and a 50 pint that are very similar. The 40 pint has the e3 error. Experimenting with the 50 pint, I found if I disconnected a particular sensor I got the e3 error. That sensor is a little can with two black wires (smaller than a AAA battery but shaped like that). It is attached to the cooling coils so must be a temperature sensor. This is not the little circuit board sensor mounted in the middle of the radiator in a plastic box/clip thing.

I am now about to see that part to see if I can replace it.

"CH 01" shows on the display screen

This will need to be serviced. LG has a 5 year warranty on these models. They usually will tell you of a service center nearby which will service it free of charge since it is under warranty. If you do not live near a service center they may ship you a replacement and you send your old dehumidifier back to them. Make sure you have your reciept when you contact them so they can verify it is under 5 years old.
