Honeywell Humidifier Troubleshooting 2022 Guide

Use a vacuum or air compressor to blow away any dust and debris around the intake and exhaust vents. If the condenser fins are dirty, clean them too while at it. If you have the humidity level set too high, the humidistat won’t trigger your dehumidifier since the humidity will still be within your desired setting. Your dehumidifier uses a float switch to detect water levels in the water tank.

On some humidifiers, a red light will come on when any of the electrical circuits are wet. You can remove the tank and let the base air dry for a few hours. Or you can open it up and dry the electrical components in the base with a paper towel and then let it dry.

Desiccant Dehumidifiers

Fill the base with undiluted white vinegar so the heating element is submerged. Using a space heater for indoor use can help you save money while providing soothing warmth. If you use the humidifier once or twice a week, the filter should be replaced every six weeks. Hard water also reduces the life of the humidifier filter.

Even though the capacitors still have power, unplugging reduces the chance of electrocution. In most cases, buying a new dehumidifier is faster and cheaper. You should only consider repairing the damage if you have a big or full house dehumidifier where it is cheaper to repair than it is to buy a replacement.
