Understanding the Problem
This guide covers the most common failures on the Whirlpool WED5050LW0 dryer (electric models in the WED50xx series): no heat, no tumble, long dry times, loud squeals or scraping, and intermittent operation. Below are practical, prioritized diagnostic and repair steps you can do at home with a multimeter, basic hand tools, and replacement parts. 1) Safety first - Unplug the dryer from the wall before any electrical test or internal inspection. For gas models, turn off the gas supply and disconnect the gas line only if you are qualified. Wear gloves and eye protection. 2) If the dryer won’t run at all a) Check household power: confirm two hot legs at the dryer receptacle (electric dryer should have ~240V). Check the breaker(s) and the wall outlet for visible damage. b) Inspect the door switch: press the door switch with the dryer unplugged and test for continuity with a multimeter. No continuity when door is closed = replace the door switch. c) Test the start switch and thermal fuse: if you get power but nothing happens, test start switch for continuity and test the thermal fuse (often located on the blower housing or near the heating element) — an open thermal fuse prevents motor start. 3) If the drum won’t spin but you hear the motor humming a) Remove the front panel and drum access. Check the belt for breakage — if broken, the drum will not turn; replace the belt. b) Inspect the idler pulley and drum rollers for seizure or excessive wear. If the motor hums but drum doesn’t move and the belt is intact, the motor start winding or the centrifugal switch may be failing — replace the motor assembly. 4) If the dryer runs but won’t heat (electric dryer) a) Clean the lint screen and disconnect and inspect the vent to the exterior for a clog — restricted airflow can mimic heating failures and cause long dry times. b) Test the thermal fuse for continuity (multimeter): if open, replace it. Common part used on many Whirlpool dryers is WP3392519 (verify fit for your exact model). c) Test the heating element coils for continuity. If open, replace the heating element assembly. d) Test the high-limit thermostat and cycling thermostat(s) for continuity. Any open thermostat when cold should be replaced. e) If all components show correct continuity but there is still no heat, verify proper incoming voltage at the dryer and check the electronic control board/timer and wiring for burned connectors. 5) If the dryer heats intermittently or takes too long a) Check and clean venting and lint trap thoroughly — reduced airflow is the most common cause of long dry times. b) Inspect the cycling thermostat and high-limit thermostat (they regulate heat). Replace if out of spec or intermittent. c) Test the heating element for partial breaks and the terminal connections for arcing or corrosion; reseat or replace as needed. 6) If you hear loud squealing, scraping, or rumbling a) Remove the drum and spin it by hand to feel for rough drum rollers or worn bearings. Replace drum rollers or rear drum bearing if rough or seized. b) Inspect the idler pulley bearing and motor bearings. Replace the idler or motor if noisy. c) Check the blower wheel for foreign objects and secure fit — replace if cracked or loose. 7) Basic replacement steps (typical for thermal fuse, element, belt, rollers) a) Unplug dryer. Pull dryer away from wall and disconnect vent if needed. b) Remove top/front panels per service manual (usually remove a couple of screws and lift off top). Support the front panel when detaching door switch connectors. c) Locate the component (thermal fuse on blower housing, heating element in rear housing, belt around drum and motor pulley). Remove wires (note or photo locations), remove mounting screws, and install new part. Reconnect wires in same positions. d) Reassemble panels, reconnect vent, plug in dryer, and run a test cycle. 8) When to call a pro - If you are uncomfortable working around mains voltage, dealing with gas connections, or diagnosing/replacing a motor or main control board, contact a qualified appliance technician. Safety note: Always disconnect power before servicing. For gas dryers, do not disconnect or reconnect the gas line unless you are qualified; improper gas work can cause leaks and fire hazards.
Common Symptoms
No heat, drum won’t tumble, dryer runs but takes forever to dry, loud squealing or scraping, dryer trips breaker, burning smell.
Common Causes
- Blown thermal fuse or open high-limit thermostat
- Broken dryer belt, seized drum rollers, or bad motor
- Faulty heating element or thermostats
- Clogged lint trap or venting (poor airflow)
- Wiring harness, door switch, start switch, or control board failure

Helpful Repair Tip
Start with the lint screen and exterior vent — restricted airflow is the most common cause of long dry times or overheating and is the easiest fix. For no-heat issues, check the thermal fuse with a multimeter first — if it’s open, the dryer won’t heat even if the element is good.
Frequently Asked Questions
How do I test the thermal fuse on my Whirlpool dryer?
Unplug the dryer, locate the thermal fuse (usually on the blower housing or near the heating element), disconnect its two wires, and use a multimeter set to continuity or ohms. A good fuse shows continuity (near 0 ohms). If it shows open (infinite resistance), the fuse is blown and must be replaced. Replace the fuse only after fixing the underlying cause (usually blocked vent or overheating).
Can I replace the heating element or motor myself?
Yes — if you are comfortable working with appliances and mains voltage. Always unplug the dryer first. Replacing the heating element, belt, rollers, or blower wheel is straightforward with basic tools. Replacing the motor is more involved (electrical connections and mounting) and can be heavier; if you are unsure, have a technician do the motor replacement. For gas models, do not service gas valves or lines unless qualified.
