Why is my Whirlpool AD70USS not dehumidifying?
Your Whirlpool Dehumidifier may not be dehumidifying because: * The unit could be out of refrigerant. You should follow the sweep charge procedure to find and repair any leaks. * The humidity might be too low. In this case, turn the unit off until the humidity rises. * The evaporator could be dirty, or the air filter might be blocked. Try cleaning the air filter and/or the evaporator.
What to do if my Whirlpool AD70USS Dehumidifier is not dehumidifying enough?
If your Whirlpool Dehumidifier isn't dehumidifying enough, consider these possibilities: * The area might not be sealed off properly; check for open doors and/or windows and close them. * The grilles could be obstructed. Ensure that the unit and surrounding items are positioned so that the grilles aren't blocked. * The evaporator could be dirty, or the air filter might be blocked. Try cleaning the air filter and/or the evaporator. * There might be a low refrigerant charge. Follow the sweep charge procedure to locate and repair any leaks. * The unit might be too small for the area. Try closing off the area to make it smaller.
How to fix a Whirlpool Dehumidifier fan that won't run but the compressor does?
If the fan on your Whirlpool Dehumidifier isn't running but the compressor is, it could be due to these reasons: * The fan motor might not be getting power. Check the wiring and repair or replace as necessary. * The fan motor might be defective. Replace the fan motor. * The fan blade could be jammed. Remove any obstruction, and replace the blade if it's damaged.
What to do if Whirlpool Dehumidifier fan runs but the compressor doesn't?
If the fan runs but the compressor doesn't on your Whirlpool Dehumidifier, consider the following: * For mechanical models: the deicer thermostat may be open. Allow the evaporator coil to thaw. If it remains open after thawing, replace the deicer thermostat. * For electronic models: the thermistor may be out of range, or the evaporator temperature is less than 30°F. If the unit is in defrost mode, raise the room temperature. Otherwise, run diagnostics and replace the electronic control if needed. * The compressor overload or relay could be defective. Check both components and replace if defective. * The compressor windings might be open. Check continuity and replace if one or both windings are open.
Why won't my Whirlpool Dehumidifier run? (no fan or compressor)
If your Whirlpool Dehumidifier won't run (no fan or compressor), here's what to check: * Ensure the unit is turned “ON” and set dry enough. Set the control to “CONTINUOUS” to allow the fan and compressor to run regardless of the ambient humidity. * Verify the unit has power: * Make sure the power supply cord is plugged in. * Ensure the outlet has power; if not, have a qualified electrician correct the issue. * Check the bucket: * Empty the bucket. * Make sure the bucket is installed properly. * Check the bucket In/Water Level switch; replace it if defective. * Inspect the power supply cord and internal wiring. Repair or replace any defective parts. * Run diagnostics to check the humidistat. Replace the electronic control if needed.
