Common Dehumidifier Problems

People in places that get a lot of humidity, especially in the warmer months, are in need of a dehumidifier to keep excessive moisture out of the air. However, like all equipment in your house, it can be prone to certain functional problems, prompting a visit from your friendly HVAC contractor. Here are some of the most common dehumidifier problems to watch out for:

No Power

Is your dehumidifier not turning on? Disconnect its main power plug from the socket and plug something else in. If it also doesn’t turn on, you might have a problem with your electrical system. Otherwise, the equipment’s safety device might have been pulled, which could happen should the reservoir fill up completely.

Reservoir Doesn’t Fill

Check your unit’s humidity detector, if it has one. This functions pretty much like your heater’s thermostat, only instead of measuring temperature, it gauges the amount of moisture in the air. If the humidity level it has set to has already been achieved, the detector will keep the unit from operating and taking in more moisture for the reservoir.

Frozen Evaporator Coils

You will know that your dehumidifier is working well if its evaporator coils remain at a very low temperature. However, this could also lead to the coils freezing in the middle of operating, which could mean your room’s temperature might be too low for your dehumidifier.
