Understanding the Problem
This guide covers the most common problems owners see with the Whirlpool WED5050LW0 electric dryer — no heat, won’t start, drum not tumbling, excessive noise, and long dry times. Below are step-by-step diagnostic and repair procedures you can follow at home. 1) GENERAL PREP: Unplug the dryer (turn off the 240V breaker) before any inspection. Remove lint and clear the vent to rule out airflow issues. Keep a multimeter, nut drivers, and a nut set handy. 2) IF THE DRYER HAS NO HEAT: a) Confirm power: Verify both 120V legs are present at the dryer outlet (should read ~240V across the two hot terminals and ~120V hot-to-ground). If you don’t have full voltage, check the household breaker or outlet. b) Check the thermal fuse: Locate the thermal fuse (usually mounted on the blower housing/back) and test for continuity with a multimeter. No continuity = replace thermal fuse. c) Test the heating element: Remove rear access panel, inspect element coils for breaks or burn spots. Test continuity across the heating element; no continuity = replace heating element assembly. d) Test thermostats/thermal cutoffs: Test the cycling thermostat and high-limit thermostat(s) for continuity. Any open thermostat when cold indicates failure—replace. e) Check the timer or control and wiring: If all components show continuity and proper voltage, the issue may be in the control/timer or wiring. 3) IF THE DRYER WON’T START OR WON’T TURN ON: a) Verify power at the outlet and the dryer terminal block. b) Test the door switch: With the door closed, switch should show continuity. Replace if open when pressed. c) Test the start switch and motor: Use a multimeter to test start switch continuity and check motor for continuity on windings. If the motor hums but doesn’t start, the start components (centrifugal switch or start capacitor in some designs) or motor may be bad. d) Inspect drive belt and idler: A snapped belt will allow the motor to run but the drum won’t turn. 4) IF THE DRUM WON’T TUMBLE OR TURNS SLOWLY: a) Check the belt: Remove front panel/drum and inspect belt for breakage or severe wear; replace if damaged. b) Inspect drum rollers, axle, glides, and idler pulley: Worn rollers or seized idler will impede rotation and make noise—replace worn parts. c) Check motor: If the motor is seized, the drum will not turn; replace motor. 5) IF THE DRYER IS LOUD OR MAKES RUMBLING/SQUEALING: a) Check drum rollers and bearings for wear or flat spots. b) Inspect idler pulley and tensioner for worn bearings. c) Remove and inspect the blower wheel for debris or damage. Replace the part that shows play or roughness. 6) IF CLOTHES TAKE TOO LONG TO DRY: a) Clean lint filter and the entire vent path (rear hose, wall vent). b) Check the heating element and thermostats (see No Heat steps). c) Confirm correct cycle selection and load size. 7) BASIC REPAIR STEPS (example: replace thermal fuse): a) Unplug dryer and access rear panel. b) Disconnect the wires from the thermal fuse (note wire locations or take a photo). c) Remove the mounting screw(s) and replace with OEM thermal fuse for this model. d) Reconnect wires, reassemble, restore power and test. SAFETY NOTE: Always disconnect power before servicing, and verify the dryer is electric (WED prefix indicates electric). If you’re not comfortable working with 240V wiring or suspect gas components (not applicable for this model), call a qualified technician.
Common Symptoms
No heat, dryer won’t start, drum won’t turn, loud squealing or rumbling, long dry times, dryer trips breaker.
Common Causes
- Blown thermal fuse or failed thermostat
- Broken heating element or open element coils
- Bad drive belt, seized drum rollers, or motor failure
- Clogged venting/poor airflow
- Faulty door switch, start switch, or control board
