Good Morning Mark, thank you for your post!

I see that your Frigidaire dehumidifier is displaying an error code of "ES" and you would like to the meaning of that error code. The "ES" error code stands for evaporator thermistor error. This could be a possible problem with your control panel, thermistor, or a wiring harness. I would recommend contacting your manufacturer for further assistance with your dehumidifier. Best of luck! -Matt

"For the above error codes, Power the unit off, and then unplug the unit for 15 minutes. Plug in and power on. If the issue persists, please contact customer service."

Hello - Typically error code F2 indicates a sensor failed has occurred on the dehumidifier. You may want to contact your manufacturer to verify if the part is available and can be replace. Some do, some don't. Also confirm if the unit has a limited warranty on such concern.

Thanks for the post by Posted by Bill L on Jul 14, 2012.
I decided to take a chance and order the new Sensor assembly $20.50 and install it in my LG LD651EBL Dehumidifier which was giving me ch 67 errors. Wala, it worked, the error code is gone and the dehumidifier is now working perfectly! Thanks

Faulty tube sensor.

F1 is room temperarure sensor error. F2 is tube temperature sensor error.

The room sensor usually is located in the front of the condenser. The tube sensor is usually plugged in a tube near the condensor.

The tube temperature sensor (thermistor) should be about 10K ohms.

I Had an E error (not an E1 error) when I was fiddling with my humidity/temp sensor on the face of the radiator fins (behind air filter).  The sensor was WET.  I dabbed it dry, let it sit all day, and re-assembled.  It works fine now.
