Expert Advice for Home Improvement & DIY Repair
Dehumidifier Doesn't Work
If your dehumidifier shows no signs of life:

1) Check the power. Be sure it is plugged into a working outlet and turned on.

2) Unplug the dehumidifier unit and check the power cord. If necessary, replace the cord.

3) Remove the cover panel.

4) Look for ice. If you see any ice blocking parts, let the ice melt and do not use the unit until the room temperature exceeds 65 degrees Fahrenheit (most dehumidifiers are not designed for use in colder spaces and may freeze up). Many people find that, by unplugging the unit and waiting about 30 days into the season, the problem is solved.

5) Remove and test the overflow cutoff switch.

6) Remove the humidistat and check it. Replace it if necessary.

7) If the unit still doesn’t work, call a repairperson—the compressor motor or the relay and overload switch may be the problem.
