Tip & How-To about Whirlpool WED9200SQ Electric Dryer

Dryer Dry Time Appears to Jump or Stall During Auto Dry Cycles

The operation of dryers during the Auto Dry Cycles is based on the moisture content of the clothes as they cycle over the moisture sensor. At the start of the cycle, the default estimated time is displayed depending on the cycle selected. The moisture sensor feeds information to the control based on the "wetness' of the clothes during the first 5 minutes of the cycle. The control then calculates and display a new estimated time making the time appear to "jump".

Recalculation happens again based on the reduction in the "wetness" of the clothes when the Estimated Time Remaining is between 15 to 5 minutes. The control will extend the cycle and display the Estimated Time Remaining unchanged if it "sees" no significant reduction in the wetness level of the clothes. The dryer will run longer than initially projected and give the appearance that the displayed time has "stalled".

Clean the sensor bars for any films or dirt build up to make sure it sends accurate information to the control. Level the dryer front to back and side to side to ensure the clothing will tumble properly and making good and proper contact with the moisture sensor bars. Check the dryer vent duct for any restriction to ensure a good air flow as the operation of the Auto Dry Cycles is based primarily on the air flow condition.

It is highly recommended to clean the lint filter before every load and make sure the dryer is grounded at the wall plug.

Whirlpool gas dryer (WGD9450WR1) not drying on auto-cycles


try cleaning the 2 silver senser bars located inside the dryer drum on the door side with isopropyl alcohol and lint free wipes,these bars sense moisture and control timer speed,and when they get coated with the chemicals in dryer sheets they become coated and can no longer sense the damp clothes (these sensers use capacitance to sense moisture)

Takes 4 ever to dry clothes. Will run & run when on auto dry.


If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.Normally, this is what happens during an automatic cycle: The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees. When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.) The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again. This cycle continues until the clothes are dry. But...if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.

My dryer does not completely dry the clothes when we use the dryness sensing option. It does fine when we use the timer. Is there a moisture sensor that I might be able to replace ?


Dryers with electronic control and auto dry cycle indeed use moisture sensors for the auto drying to work. The problem is absolutely associated with the failure of the moisture sensors, especially when the timed dry cycle works fine. Either the connection of the sensors to the electronic control is loose or the sensors are covered with thin film that prevents it to sense the proper moisture content of the clothes.

Clean the moisture sensor bars thoroughly and make sure its connections are snug fit. Reseat the connections several times to clean off dirt and corrosion build up in the connectors and terminals. The last thing to look into is the electronic control if all resort fail to address the issue, that is, clean sensor bars and good terminal connections.

Indicate the exact model number of the dryer should you need further or more specific troubleshooting and repair advice.

why is the dryer not turning off


Hi, If your dryer seems to run forever and doesnt turn off, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.
Normally, this is what happens during an automatic cycle:
The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees. When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.) The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again. This cycle continues until the clothes are dry. But if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.
