Hello,

First, make sure the reservoir is empty. If you plug the unit in and see a green power light, but the unit won't run, make sure the reservoir is properly inserted. Many dehumidifiers have switches or sensors to make sure that the reservoir is placed so that it won't leak. Look for these sensors and make sure the reservoir is engaging them. If your dehumidifier has a float or switch to indicate a full reservoir, make sure this switch isn't being tripped accidentally.

Good luck.

clean the dust off of the condenser in the front or the filter if it has one. no air flow results in overheating and no condensation across the evaporator coil.
