Understanding the Problem
This guide covers the most common problems owners see with the Whirlpool WED5050LW0 electric dryer: not heating, long drying times, loud noises, drum not turning, and not starting. Below are prioritized diagnostic steps and practical fixes you can do at home. 1) Confirm the symptom and basic checks: (a) If the dryer won't start, make sure the dryer is plugged in, breakers are on, and the door is fully closed. (b) If it runs but doesn't heat, confirm the dryer drum turns and the dryer gets power (see step 2). (c) If it's noisy or vibrates, note when the noise occurs (spin up, running, or stopping). 2) Check power first (electric models): (a) Reset the circuit breakers for the dryer — electric dryers need two live legs (240 VAC). (b) Use a multimeter at the dryer terminal block or outlet to confirm ~240 VAC across the two hot terminals and ~120 VAC from each hot to neutral. No 240 V = electrical issue or tripped/miswired breaker — call an electrician. 3) Not heating — prioritized parts to check (in order): (a) Lint screen + vent: remove lint and run a test cycle. A clogged vent will dramatically reduce heating. Clean vent to outside. (b) Thermal fuse: locate on the blower housing or exhaust duct; test for continuity with a multimeter. A blown thermal fuse = no heat and dryer usually runs. (c) Heating element assembly: check element for visible break/damage and test continuity across element coils. (d) High-limit thermostat / cycling thermostat: test for continuity; replace if open when cold or if out of range. (e) Wiring and control board connections: inspect for burned connectors or open wires. 4) No heat — step-by-step fix example (thermal fuse or element): (a) Unplug dryer. (b) Pull dryer away from wall and remove rear access panel (or front panel depending on model). (c) Locate thermal fuse on blower housing and disconnect its two wires. Test with a multimeter for continuity — no continuity = replace fuse. (d) To test heating element: disconnect the element wires and test continuity from terminal to terminal; an open reading = replace element. (e) Replace failed component and reassemble. Re-check vent and run dryer to verify heating. 5) Dryer runs but drum doesn't turn — checks and fixes: (a) Open the cabinet and inspect the drum belt for fraying or break. (b) Check motor: if you hear the motor hum but it won't turn, the motor or start capacitor may be bad. (c) Inspect idler pulley and drum rollers—replace worn rollers, glides or idler. Replace the belt if broken. 6) Loud noises / squealing / thumping — checks and fixes: (a) Remove front or rear panel and spin the drum by hand. Listen for rough bearings or rubbing. (b) Inspect drum rollers, wheel bearings, felt glides, idler pulley and blower wheel for damage. Replace worn parts. (c) Remove any objects from the drum or blower housing. 7) Long dry times — common causes & fixes: (a) Clean lint trap, inside lint trap housing and moisture sensor bars. (b) Clean or replace the vent hose; remove long lint build-up in the vent run to the outside. (c) Check heating element and thermostats if the dryer heats weakly. 8) Door switch / won't start — test and replace: (a) With the dryer unplugged, access the door switch (usually behind the front panel or console). (b) Use a multimeter to test continuity when the door is closed. No continuity = replace door switch. 9) Run a final test cycle: after repairs, reassemble panels, restore power, and run an empty timed cycle to verify that the issue is fixed and there are no error codes. Safety note: always unplug or disconnect power at the breaker before opening panels or touching electrical connections. Use a multimeter rated for the job and take care when working with 240 VAC. If you are not comfortable testing live voltage or replacing major components, contact a qualified appliance technician.
Common Symptoms
Not heating, long drying times, loud noises during operation, drum not turning, dryer won't start or tumbles intermittently.
Common Causes
- Clogged lint screen or exterior vent restricting airflow
- Blown thermal fuse or failed heating element/thermostat
- Broken drum belt, worn rollers, or failing motor
- Faulty door switch, start switch, or control board

Helpful Repair Tip
To confirm a heating failure quickly: with the dryer running, carefully feel the vent outlet (use caution) — if airflow is strong but air is cool, suspect heating element/thermal fuse/thermostats; if airflow is weak, clean the vent first.
Frequently Asked Questions
My dryer runs but doesn't heat — what's the most likely cause?
Most commonly a blown thermal fuse or a clogged vent. Start by cleaning the lint screen and vent to the outside. If airflow is OK but the dryer still won't heat, test the thermal fuse for continuity; if it's open, replace it. Next check the heating element and thermostats with a multimeter.
How do I know if my dryer motor or belt is bad when the drum won't turn?
If the motor hums but the drum doesn't turn, check the belt—if it's broken you'll see it separated or hanging loose. If the belt is intact but the motor hums without turning the drum, the motor (or internal start components/capacitor) may be failing. Also inspect the idler pulley and drum rollers for seized bearings that can prevent rotation.
