Your electrical dryer plays the important role of drying out your clothes, so any malfunctions can be very frustrating and inconveniencing. One of the most common issues with electric dryers is a failure to produce heat, or generating insufficient heat to effectively dry your laundry. Before you call in a serviceman/electrician to fix the problem, read on for simple troubleshooting tips that may solve the underlying problem and get your dryer functional.
High limit / cycling thermostat
A failed high thermostat eventually causes your dryer to stop producing heat. The thermostat is often mounted on the heating chamber and is designed to trip whenever the dryer is about to overheat, often due to an obstructed exhaust vent. This thermostat doesn't usually reactivate recurrently, so once it trips to interrupt the circuit to the heating element, it will cause a no heat symptom.
Fix the problem by reactivating the thermostat manually and removing any obstruction on the dryer vent system to prevent future overheating. If this doesn't solve the problem check the thermostat for continuity with a multi-meter and replace it if it isn't allowing current to flow through.
Unlike the high limit thermostat, a cycling thermostat is usually designed to reactivate repeatedly, shutting the flow of current on and off so as to maintain the right amount of warmth within the dryer drum. Over time, the thermostat can become defective, affecting the ability of the dryer to cycle on and off, and eventually resulting in a no heat symptom. Locate the cycling thermostat on the blower housing, check for continuity and replace it if faulty.
A faulty timer or thermal fuse
The timer on your electrical dryer is typically located in the control console of the dryer, and is responsible for controlling the dryer motor and heat circuit. A defect in the timer can cause the dryer to fail to produce any heat. To fix the problem, check the timer contacts for any loose connections and soldering them in place to restore the flow of current to the timer.
A thermal fuse is typically located in the dryer's cabinet and is designed to prevent your dryer from overheating. Once it blows, the entire appliance can't function, so you need to check the fuse for continuity and replace it if broken.
Damaged heating element
Problems with your dryer's heating element could cause insufficient heating within the unit. The element is basically a coil of heating wire that conducts electricity and generates heat which is then absorbed by air in the dryer's chamber. If your appliance won't effectively dry your clothes, the element could be damaged and should be replaced.Share
