Understanding the Problem
If your NED4655EW dryer tumbles but clothes stay damp or it takes far longer than normal to dry, the problem is usually with the heating system or airflow. Electric dryers most commonly lose heat because of a failed thermal fuse, a broken heating element, or a bad high-limit/cycling thermostat. Restricted venting and lint buildup can also prevent hot air from circulating and make it seem like the dryer isn’t heating. For gas dryers (if your model is gas-configured), problems most frequently involve a faulty igniter, gas valve coils, or a blocked vent. Diagnosis starts with simple, safe checks you can do without disassembly: confirm the dryer is getting the correct power (for electric dryers: two 120V legs for 240V total), clear the lint screen and exterior vent, and run a short cycle while listening for normal glow/ignite behavior. If those quick checks don’t reveal the issue, move on to testing components such as the thermal fuse, thermostats, and heating element (or igniter/valve coils for gas units) with a multimeter. Always disconnect power (and gas supply for gas models) before opening the dryer.
Common Symptoms
Dryer tumbles but clothes remain damp; long drying times; dryer runs but no heat; dryer trips breaker (electric) or clicks without igniting (gas); dryer overheats and then shuts off on some cycles.
Common Causes
- Blown thermal fuse caused by overheating or blocked venting
- Broken heating element (electric) or failed igniter/gas valve coils (gas)
- Bad high-limit or cycling thermostat, or poor electrical supply

Helpful Repair Tip
First clear the lint screen and disconnect the external vent hose; run the dryer on air/fluff and check if airflow at the vent is strong. If airflow is good but there’s no heat, test the thermal fuse for continuity with a multimeter—this is a quick, inexpensive part that often fixes no-heat issues.
Frequently Asked Questions
How do I check the thermal fuse on my NED4655EW dryer?
Unplug the dryer. Locate the thermal fuse (usually on the blower housing or near the heating element) and remove the connectors. Test it with a multimeter set to continuity or resistance—a good fuse shows continuity (near 0 ohms); a blown fuse shows open circuit. Replace the thermal fuse if it’s open. Also inspect and clean the lint path and external vent before replacing the fuse since overheating from blocked ventilation commonly causes fuse failure.
Can I replace the heating element or igniter myself and how much does it cost?
Yes, many homeowners can replace a heating element (electric) or igniter (gas) with basic tools. Always disconnect power (and gas for gas dryers) first. Typical part costs: heating element or igniter $25–$70, thermal fuse $10–$25, thermostats $10–$30. If you’re unsure about diagnosing electrical or gas components, or if the repair requires vent or gas-line work, hire a qualified technician for safety.
