Zenith dehumidifier is freezing up on the front near the air intake.

Coils can freeze if the room is extremely hot. Usually, though they freeze because the path for air flow is reduced. Check input and output grilles and coils for dirt and dust and clean as necessary.

Take out bucket. Remove front cover two screws bottom left and right. Just inside lower left is a wiring harness with a clamp. Pry off and clean rust from clamp and tubing it attaches to. (if you put the bucket in and hold sensor between fingers the humidifier will start to work) Reattach clean sensor to clean copper tubing.

Hi,

Here is a tip that explains what can be happening to make the dehumidifier showthat the bucket is full when it is not.

Dehumidifier Problem It shows Bucket Full

If the bucket is not really full, it usually means the when the bucket was remove and reinstalled, it wasn't installed properly. Turn the unit OFF and unplug it. Remove the bucket and look inside of it, to see is there is a float valve. If so, it may be stick in the UP position. Jiggle it to make it return to DOWN position.

If your unit does not have afloat valve, reinstall the bucket, making sure it fit's "squarely" into the bucket holder. Once installed properly, the bottom of the tank should not tilt down at all. And it should be making contact with the bucket removal safety switch.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

Evan, a dirty or clogged air intake filter can cause it to freeze, as well as obstructed air flow around the unit. Maintain a minimum or 12" clear air space all around the dehumidifier. Also operating the unit in temperatures below 40 degree (F), will also cause the coils to freeze. In addition, low refrigerant in the compressor can cause the coils to freeze. In which case, recharging the gas should solve the problem, And finally, worse case scenario is that the defrost cycle sensor has failed and needs to be replaced.

You may, but more than likely, the air intake filer needs to be cleaned and the compressor coils wiped down and cleaned. After cleaning the coils, a light coat of WD40 helps to preserve them.

Before attempting any cleaning or service work, turn the unit OFF and unplug it from the wall outlet and allow it to thoroughly thaw. Keep in mind, a dehumidifier will freeze up, if the room temperature is below 40 degrees. Also, where you have it installed may be a problem. Particuarly, a basement. Where the air temperature is colder at floor level.

In case you have misplaced your Owners Manual, I have included a link to it that you can download & print for future reference. Be advised, your Model Number is not for a Sunbeam Dehumidifier, it's for a Comfort Aire dehumidifier that's manufactured by Heat Controller Inc.

Hi,

The coils you see on the back of your dehumidifier are the evaporator. When the unit runs, the coils get very cold. As the fan draws the room air over the coils, the humidity in the air condenses out of the air onto the cold coils. But, if the temperature of the air the fan draws over the coils is too cool, the humidity that condenses out of the air freezes on the coils. To remedy this problem, you can try any of these: Warm up the room the dehumidifier is in. Put the dehumidifier on a sturdy table (the room air is coolest near the ground).

Turn the unit off until the room warms up.
Good luck

Take care.

This can happen if the Temperature in your room is too low. You can work around it and place a 40 watt bulb near the the inlet of the humidifier to warm up the air a bit. Also if the humidity level in your room is already too low this can cause your dehumidifier to freeze up.

Make sure the filter is clean and plenty of air comes through, when coils freeze it is usually caused by low air flow coupled with lots of humidity and low air temperature in the space to be cooled. Clean the filter, fan and gently brush all dust and debris from the intake of the cold coil and retry it. If the basement is already cool and you are trying to dehimidify you should use a dehumidifier that features defrost controls.
