Sos! my whirlpool dryer is blowing cold air – what’s going on?
What To Know
- Lint accumulates in the filter as you dry clothes, and if it’s not cleaned regularly, it can restrict airflow and prevent the heating element from working properly.
- If it becomes damaged or malfunctions, it can prevent the heating element from turning on or cause it to cycle on and off erratically.
- Disconnect the dryer from the exhaust vent and use a vent brush to remove any lint or debris that may be blocking the airflow.
When your Whirlpool dryer starts blowing cold air instead of the expected warm breeze, it can be a frustrating and perplexing inconvenience. Don’t worry, you’re not alone! Many homeowners encounter this issue, and understanding the potential causes can help you restore your dryer to its efficient operation.
Common Causes of Cold Air in Whirlpool Dryers
1. Clogged Lint Filter
A blocked lint filter is a common culprit behind cold air in dryers. Lint accumulates in the filter as you dry clothes, and if it’s not cleaned regularly, it can restrict airflow and prevent the heating element from working properly.
2. Faulty Heating Element
The heating element is responsible for generating the heat that dries your clothes. If it malfunctions or burns out, your dryer will blow cold air.
3. Defective Thermistor
The thermistor is a sensor that monitors the temperature inside the dryer. If it fails, it can send incorrect temperature readings to the control board, which may result in the heating element not being activated.
4. Overloaded Dryer
Overloading your dryer can strain the heating element and cause it to overheat. When the element overheats, it may shut off as a safety measure, resulting in cold air being blown.
5. Damaged Thermostat
The thermostat regulates the temperature inside the dryer. If it becomes damaged or malfunctions, it can prevent the heating element from turning on or cause it to cycle on and off erratically.
6. Faulty Control Board
The control board is the brain of your dryer, coordinating all its functions. If the control board malfunctions, it may not send signals to the heating element to turn on.
7. Blocked Exhaust Vent
The exhaust vent allows moisture and heat to escape from the dryer. If the vent becomes blocked or clogged, it can restrict airflow and prevent the dryer from heating properly.
Troubleshooting Tips
1. Clean the Lint Filter
Start by checking and cleaning the lint filter thoroughly. Remove any lint or debris that may be blocking the airflow.
2. Inspect the Heating Element
Unplug the dryer and remove the back panel. Inspect the heating element for any signs of damage or burn marks. If it looks damaged, it may need to be replaced.
3. Test the Thermistor
Use a multimeter to test the thermistor for continuity. If it doesn’t show continuity, it needs to be replaced.
4. Avoid Overloading the Dryer
Follow the manufacturer’s guidelines for the maximum load capacity of your dryer. Overloading can strain the heating element and reduce its efficiency.
5. Check the Thermostat
Disconnect the wires from the thermostat and use a multimeter to test for continuity. If it doesn’t show continuity, replace the thermostat.
6. Reset the Control Board
Unplug the dryer for 10 minutes to reset the control board. This may resolve any minor glitches or software issues.
7. Clean the Exhaust Vent
Disconnect the dryer from the exhaust vent and use a vent brush to remove any lint or debris that may be blocking the airflow.
