This is a problem that can be caused by things that don’t have to do with the dehumidifier itself. First, you are going to want to make sure that it is plugged into a functioning outlet. You are also going to want to double check the corresponding circuit breaker to make sure that it has not been tripped. If all of these are good, it may not turn on due to a float assembly, humidistat, auto shutoff feature malfunction, control board, or sensor. It all depends on the severity of the problem as to whether or not you are going to need to call in a professional.


This is a common occurrence with dehumidifiers, but it needs to be dealt with immediately.
