Understanding the Problem
If your NGD4655EW2 drum tumbles but the dryer doesn't produce heat, the issue is almost always in the gas ignition or high-limit safety circuit rather than the motor or belt. Gas dryers require a working igniter and gas valve coils plus intact safety thermostats and thermal fuses to light and maintain a flame. A single failed safety device will prevent heating to avoid fire risk. Common failed components on this model are the thermal fuse (which shuts the heater circuit if the dryer overheats or vents are clogged), the igniter (the part that glows and lights the gas), and the gas valve coils (which open the gas valves when the igniter is hot). Less commonly, a failed high-limit thermostat, flame sensor, or wiring/thermostat connection can be the cause. Start by checking the simplest safety items (thermal fuse, venting) and then test the ignition components with a multimeter and visual inspection.
Common Symptoms
Drum tumbles but no heat; dryer runs a cycle but clothes remain damp; sometimes a short flicker of heat or clicking from the rear; dryer stops heating after a few minutes.
Common Causes
- Blown thermal fuse or open high-limit thermostat (safety cut-out)
- Failed igniter that does not glow or opens when hot
- Bad gas valve coils or gas valve assembly not opening

Helpful Repair Tip
First check the vent and exhaust for restriction and then test the thermal fuse for continuity with a multimeter — if the fuse is open, replace it before testing ignition parts.
Frequently Asked Questions
How do I test the thermal fuse and igniter?
Unplug the dryer and locate the thermal fuse (usually on the blower housing or exhaust duct on the rear). Remove the fuse and test continuity with a multimeter — an open reading (OL) means it's blown and must be replaced. To test the igniter, disconnect power, access the igniter, and inspect visually for cracks or breaks. Test for continuity with a multimeter; many igniters will show continuity when cold but can still fail under load, so if igniter appears intact but doesn't glow during a cycle, replace it. Always confirm power is off and follow safety steps before testing.
Can I replace these parts myself, or should I call a technician?
If you are comfortable working with appliances and can safely disconnect power and remove panels, you can replace parts like the thermal fuse, igniter, and gas valve coils yourself — they are common DIY fixes. However, because gas dryers involve gas, flame, and safety devices, call a qualified technician if you smell gas, if gas valve replacement is required and you are not experienced, or if multiple components have failed. Always verify part numbers for NGD4655EW2 and follow the manufacturer's safety instructions.
