My six years old dehumidifier seems to start working inconsistantly
since last winter. I had that dehumidifier in my basement working for
six years without any problem. During the winter, it was not doing
anything because the air was dry. When spring came, I found that the
dehumidifier didn't run to dry the air. I thought the air was dry
enough that the dehumidifier would not automatically kick in;
therefore, I didn't pay attention to it. But when summer comes, and
humidity level in the basement goes up, I find that the dehumidifier
still doesn't kick in. Something is wrong with the dehumidifier.
Seem like I can force it to start running by powering it OFF and then
ON. It will start running for a while. But not long enough to dry
the air. Since then, I notice that it will sometimes automatically
kick in. But it is OFF most of the time when it should be ON. I have
intentionally set the humidity level of the dehumidifier to quite low
(such as 40); but that doesn't trigger the dehumidifier to kick in.
Consequently, the humidity level in the basement has gone above 60.
Does this mean that the dehumidifier has reached the end of its life?
Is there any "simple fix"?
Thanks in advance for any info.
