Troubleshoot your Dehumidifier

Changing water container of dehumidifier at home. Dampness in apartment. Modern technology

A dehumidifier lowers the humidity level in your home by pulling moisture from the surrounding air.  Dehumidifiers make your home less susceptible to unwanted things like dust mites, mold, and mildew and they also help reduce irritation to your skin and respiratory system. If you have one of these handy appliances, but it starts to not work properly, it is most likely an easy fix. So keep reading to learn what to check for to get your dehumidifier back up and running!

Dehumidifier is Not Running

If the indicator light is on but the appliance is not running- check the water level in the tank. A switch will turn the machine off when it is full so it does not leak or spill. Simply empty the reservoir tank and place it back into the dehumidifier.

If the reservoir tank is not full, the switch could have been triggered by the position of the tank or by an external force. Readjust the tank and push the switch yourself.

Dehumidifier Runs Infrequently

If the dehumidifier is running infrequently or ineffectively- check the humidistat control and try adjusting it to a drier setting. Clean the filter, replacing the filter annually or if it has any damage.

Dehumidifier Runs All the Time

If the dehumidifier is constantly running and not filling the tank at all, it is most likely an issue with the refrigeration system and will have to be looked at by a repair professional.

Dehumidifier Freezes or Frosts Up

If there is frost on the coils in the back- the room that the dehumidifier is in is probably too cold, so turn the temperature of the room up if possible. You could also move the unit to a higher location in the room, or closer to a heat source. Some units have an automatic defrost function as well. If you live in a particularly cold area, it is suggested to get a dehumidifier that specifically works in lower temperatures, as frost build up greatly decreases the effectiveness of the appliance.

If no air comes out while it is running- the fan motor is likely burned out and can be replaced. If the air is weak, make sure the dehumidifier has adequate space behind it and around it to allow for proper air flow. Avoid putting it right up against the wall or other objects.

Some issues will require a professional to come check it out, but make sure you check these common problems first. It is probable that you can resolve the matter yourself!
