Question about Heating & Cooling

1 Answer

Own a whirlpool low temp dehumidifier model AD75USTO that collects very little water despite running all day in a basement with humidity level of 70% at about 60 deg F. I opened the case and saw that the coil remains frozen. I also noticed a thermistor mounted on the coil. Possibly this circuit is not working. I sprayed the thermistor with a freeze spray during operation and the compressor didn't do anything?? Help!!

    Is it low in freon or is the compressor not cycling OFF? I should've been clearer with my original question, spraying the thermistor with freeze spray should cause the coil thermistor to send a signal to the control board to deice, i.e. switch the compressor OFF, etc. The thermistor varies from 50-80Kohms (measuring after using freeze spray and normal operating temp. Not sure if that's the right values, but at least it responds to temp changes. Bad control board perhaps?

New Whirlpool gold dehumidifier last summer. Used since then. It still runs (fan) but no water is being taken from the air. I clean the filters, looked at coils, they are like brand new. I hate to give up,...


Kim, it may simply be a case of the humidity extraction level being set to HIGH. Lower it to 35%. If it's an analog unit (No LED Display) turn the humidity extraction knob to Maximum. More often than not, this will solve the problem. If it doesn't the humidity sensor may need to be replaced.

I hope this helped you and thanks for choosing FixYa.

Whirlpool DEHUMIDIFIER Model - AD70USS1 does fan NOT does not cycle off anymore in the low settings as it should


According to the Owner's Manual for your model, the fan will run continually, if the unit is set in continuous mode or if the unit is in defrost mode. Once the unit senses a rise in the humidity level, the compressor will start up again. Also, a dirty or clogged air filter will cause the fan to run more that it should.

Hope this helps you troubleshoot and solve the problem.

When do you use the dehumidifier?


In areas with poor circulation and humidity over 80%.
If the room temperature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.
