Hi, I have the same issue. I took off the plastic backside and managed a work around by removing the brown cable from the micro switch. It is now running again, but it won't get a signal when the water container is full ... so be aware when you start running it !

Plug a lamp in the socket and see if it works. If it does try the unit, if it does not do anything look for a reset. If you cannot find that (there may not be one) get the schematic and trouble shoot the unit.

The fan is mounted on a very poor quality 3 angle mount. The weight of the motor distorts the mount over time so the the fan starts clipping other fittings when spinning. You can turn the mount around so the motor hangs upright again. The latest EBACs are of very poor quality...

Frost means one of two things, low refrigerant or low airflow across the coil. The unit probably has lost it's refrigerant charge ( or some of it's charge) even though it hasn't been used.

Is it possible to download -PDF the Instruction Manual for the Ebac dehumidifier model 2400

Here is the link for the Owner's Manual off the Ebac website:

This model furnace does not come with a built in humidifier. Humidifiers are normally an optional add on. If you have a by-pass type humidifier it is none adjustable. Water level is normally float controlled and operation is control by blower circuit. When ever the blower runs the humidifier operates when in the heating mode.
