Understanding the Problem
The NGD4655EW2 is a gas dryer that commonly shows problems such as not heating, not igniting, long dry times, loud noises, or failure to start. Gas dryers rely on a small set of gas-specific components (igniter, gas valve coils, flame sensor) plus universal parts (thermal fuse, belt, rollers) — failure of any one part can produce clear symptoms. Diagnosing a gas dryer focuses on safety first (shut off gas and power) and then stepwise checks of continuity and proper airflow. Typical repairs range from inexpensive user-serviceable parts (drum belt, rollers, thermal fuse) to gas-system components that require careful testing (igniter, gas valve solenoids, flame sensor). Many failures are caused or made worse by poor venting or lint buildup — always verify airflow and vent condition before replacing major parts to avoid repeat failures.
Common Symptoms
Dryer won’t heat or ignite, dryer tumbles but no flame, dryer takes excessively long to dry, loud scraping or thumping noises when tumbling, dryer won’t start or stops mid-cycle.
Common Causes
- Failed igniter, gas valve coils, or flame sensor preventing ignition
- Blown thermal fuse or failed high-limit/ cycling thermostat cutting power to the gas valve
- Mechanical wear: broken belt, worn drum rollers or idler pulley, or clogged venting restricting airflow

Helpful Repair Tip
Before ordering parts, confirm the failure with simple tests: check vent airflow, test thermal fuse and cycling thermostat for continuity with a multimeter (with power disconnected), and observe the igniter and gas valve behavior during a heat cycle — replace the ignition components only after confirming the igniter is glowing or the gas valve coils are not opening.
Frequently Asked Questions
How can I tell if the igniter or gas valve is the problem?
Start by ensuring the dryer is getting power and the gas supply is on. With the dryer running on a heat cycle, open the dryer cabinet (power and gas off first) or watch the burner through an observation slot: a working igniter should glow orange during a heat call and then the gas valve should open to produce a visible flame. If the igniter never glows, test it for continuity with a multimeter — no continuity or visible damage means replace it. If the igniter glows but no flame appears, the gas valve coils or flame sensor are likely faulty. Because gas components are involved, if you’re not comfortable testing or replacing them, call a qualified technician.
Can I replace NGD4655EW2 parts myself, or should I hire a technician?
You can replace many parts yourself if you have basic mechanical skills and the right tools: drum belts, rollers, idler pulleys, and door switches are typical DIY repairs. For electrical checks (continuity testing) follow safety steps: unplug the dryer and shut off gas before opening panels. For gas-system components (igniter, gas valve coils, flame sensor) be cautious — incorrect installation can cause gas leaks or unsafe operation. If you’re unsure about gas diagnostics, smell gas, or detect a leak, stop and call a licensed appliance technician.
