Whirlpool Dryer Won't Start: Decoding the "Sensing" Message

A Whirlpool dryer refusing to start and displaying a "Sensing" message can be frustrating. This seemingly simple error code often masks a variety of underlying issues, from minor inconveniences to significant component failures. This comprehensive guide will walk you through troubleshooting this problem, helping you diagnose the cause and potentially save on costly repair bills.

Understanding the "Sensing" Message

The "Sensing" message on your Whirlpool dryer indicates that the dryer's control board is attempting to sense the presence of clothes and their moisture levels. This is a crucial step before the dryer can initiate the drying cycle. If the dryer can't accurately sense these factors, it will prevent the cycle from starting, displaying the "Sensing" error. This safety mechanism prevents the dryer from overheating or running inefficiently with an empty drum.

Troubleshooting Steps: A Systematic Approach

Before you call a repair technician, try these troubleshooting steps. Remember to always unplug the dryer from the power source before performing any physical checks.

1. The Obvious Checks: Load and Power

  • Check the Dryer Load: The most common reason for a "Sensing" error is a simple lack of clothes in the drum. A completely empty dryer won't register a load, triggering the error message. Add a load of laundry and try again.

  • Power Supply: Ensure the dryer is properly plugged into a functioning electrical outlet. Check the breaker box to see if the circuit breaker for the dryer has tripped. Reset the breaker if necessary. If the outlet itself is faulty, try a different outlet.

  • Door Latch: Make absolutely certain the dryer door is securely closed. A slightly ajar door can prevent the dryer from starting due to safety mechanisms.

2. Sensor Issues: The Heart of the Problem

The moisture sensor is a crucial component responsible for detecting the wetness of clothes. Several issues can affect its function:

  • Dirty or Blocked Sensor: Lint and debris can accumulate on the moisture sensor, hindering its ability to accurately read moisture levels. Locate the moisture sensor (usually located near the drum, often behind a panel) and carefully clean it with a soft brush or compressed air. Avoid using harsh chemicals.

  • Faulty Moisture Sensor: If cleaning doesn't resolve the issue, the moisture sensor itself might be faulty. This requires replacing the sensor, a relatively straightforward repair for someone comfortable working with appliances. However, if you're not comfortable with appliance repair, call a professional.

  • Thermistor Issues: Another component that plays a vital role in temperature sensing is the thermistor. A malfunctioning thermistor can prevent accurate temperature readings, resulting in the "Sensing" error. Replacing a faulty thermistor will require technical expertise.

3. Control Board Malfunction: The Central Nervous System

The control board acts as the dryer's central processing unit, interpreting signals from various sensors and controlling the overall operation. A malfunctioning control board can trigger a variety of error codes, including the "Sensing" message.

  • Visual Inspection: Carefully examine the control board for any visible signs of damage, such as burnt components or loose wires. Note: This should only be attempted by individuals with experience working with electrical components.

  • Advanced Troubleshooting: Determining a faulty control board typically requires advanced troubleshooting skills and specialized tools. A multimeter can be used to test the board's circuits, but incorrect handling can cause further damage.

4. Other Potential Culprits

  • Motor Problems: Though less likely, a failing motor can sometimes lead to the "Sensing" error. A faulty motor won't allow the drum to rotate, preventing the sensor from functioning correctly.

  • Wiring Issues: Loose, damaged, or corroded wiring can disrupt the electrical signals between the sensors and the control board. Thoroughly inspect the wiring for any problems.

5. When to Call a Professional

If you've exhausted the above troubleshooting steps and your Whirlpool dryer still displays the "Sensing" message, it's time to call a qualified appliance repair technician. Attempting more advanced repairs without the necessary expertise could damage the dryer further, leading to more costly repairs.

Preventive Maintenance: Avoiding Future Problems

Regular maintenance can significantly reduce the likelihood of encountering problems like the "Sensing" error.

  • Clean the Lint Trap After Every Load: This is crucial for efficient drying and prevents lint buildup from affecting the sensor and other components.

  • Clean the Dryer Vent: A clogged dryer vent restricts airflow, reducing efficiency and potentially causing overheating. Clean the vent at least once a year, or more often if you notice reduced drying performance.

  • Inspect the Dryer Regularly: Periodically check for any visible signs of damage, loose connections, or buildup of lint and debris.

Understanding Repair Costs

Repair costs for a "Sensing" error vary depending on the actual cause. A simple cleaning of the sensor might be free, while replacing a control board could be expensive. Getting multiple quotes from reputable repair technicians is always a good idea.

Safety Precautions:

  • Always disconnect the dryer from the power source before attempting any repairs.
  • Never work on the dryer while it's plugged in or turned on.
  • If you're uncomfortable working with electrical components, call a professional.
  • Use caution when handling any internal parts of the dryer.

Conclusion:

The "Sensing" error on your Whirlpool dryer can stem from several causes. By systematically following the troubleshooting steps outlined above, you can often resolve the problem yourself. However, remember that safety should be your priority. If you are unsure about any step, or if the problem persists, don't hesitate to contact a qualified appliance repair technician. Investing in professional help ensures that the repair is done correctly and safely, extending the life of your dryer and preventing further issues.
