Understanding the Problem
The Whirlpool WED5050LW0 is a common front‑load electric dryer. Owners typically see a handful of repeat problems: dryer tumbles but doesn't heat, dryer won't start or stop mid‑cycle, long dry times, loud rumbling or squealing, and drum not turning. Below are practical diagnostic steps for each major symptom and how to fix them. 1) Dryer tumbles but does not heat 1.1 Verify power: This is an electric dryer—confirm you have 240V at the dryer. With the dryer plugged in, check the two hot legs at the terminal block or outlet with a multimeter; you should read ~240V between the two hot terminals. If you only see 120V or one leg missing, check the house breaker/fuse and the dryer cord/terminal connections first. 1.2 Check the thermal fuse: The thermal fuse is a common one‑time protective device that opens if the dryer overheats (often due to restricted venting). Unplug the dryer, locate and remove the thermal fuse (usually on the blower housing or near the heating element), and check for continuity with a multimeter. No continuity = replace fuse. 1.3 Test the heating element: Remove the rear access panel (or front depending on model) to reach the heating element assembly. Inspect visually for broken coils or burn marks. Test for continuity across the element with a multimeter—an open element means replace it. 1.4 Check thermostats and high‑limit sensor: There may be a cycling thermostat, high‑limit thermostat, or temperature sensor. Test each for continuity (they should show continuity at room temp). Replace any that are open. 1.5 Inspect venting and airflow: Restrictive venting causes overheating and can trip the thermal fuse or reduce heat. Clean lint from the lint trap, inside the cabinet, and the external vent; measure airflow at the dryer exhaust—strong steady airflow is expected. 2) Dryer won’t start (no tumble) or stops mid‑cycle 2.1 Verify power: Same as above—confirm both hot legs and proper voltage. 2.2 Door switch: With the door open the dryer should not start; with door closed the door switch should close. Unplug dryer, access the door switch and test for continuity when actuated. Replace if defective. 2.3 Start switch / motor: If you hear a humming but no tumble, the motor may be jammed or the centrifugal switch inside motor failed. If totally silent and no lights, check control board and fuses. Test motor for continuity; if motor fails to spin when 240V is applied (qualified tech only), replace motor. 2.4 Thermal cut‑outs and control components: A blown thermal fuse or faulty control board can prevent start. If the fuse is open but vents are clear, consider replacing the fuse and testing again; persistent blown fuse points to airflow or cycling thermostat problems. 3) Long dry times, clothes still damp 3.1 Clean lint screen and inside lint path: Remove and clean the lint filter and use a vacuum to clear the lint trap and surrounding area. 3.2 Check exhaust venting: Disconnect the vent at the back and run the dryer briefly (monitor safety) to feel airflow. Poor airflow = clogged vent or collapsed duct—clean or replace ducting and outside hood. 3.3 Partially failed heating element or thermostat: An element that is partially open may produce weak heat. Test element and thermostats for continuity and replace faulty parts. 4) Loud noise, squeaking, or rumbling 4.1 Drum rollers and glides: Inspect drum support rollers and front/back drum glides for wear. Worn rollers produce rumbling or squeal—replace rollers into kit. 4.2 Idler pulley and belt: A worn or seized idler or frayed belt can squeak or slap. Inspect belt for cracks and the idler for smooth movement; replace as needed. 4.3 Motor bearings: A loud growl from the motor often means failing bearings—replace the motor assembly. 5) Drum not turning but motor runs 5.1 Broken or slipped belt: If the motor runs but drum does not turn, the belt may be broken or off the drum. Replace the belt and check idler alignment. 5.2 Broken belt tensioner or drum roller: Inspect and replace broken rollers or idler. Step‑by‑step generic repair workflow (applies to many of the checks above) A. Safety first: Unplug dryer and shut off power at the breaker before opening panels or testing internal components. B. Access: Pull unit away from wall, remove lint screen and bottom/upper access panels as needed. Keep track of screws. C. Visual inspection: Look for lint buildup, scorched wires, broken element coils, worn belts/rollers, or burnt connectors. D. Electrical checks: Use a multimeter to check for continuity (thermal fuse, element, thermostats, door switch) and correct voltage at the terminal block with power on (qualified users only). E. Replace parts: Replace the failed part (thermal fuse, heating element, thermostat, belt, rollers, motor) and reassemble. If replacing thermal fuse, always address the root cause (venting/airflow) first. F. Test: Reconnect power, run a test cycle and confirm heating, tumbling, and airflow performance. Safety note: Always unplug the dryer and, for voltage checks at the terminal block, shut off the circuit breaker and use a qualified electrician if you are not comfortable working with 240V circuits. Replace one‑time thermal fuses with OEM specified parts and never bypass safety devices.
Common Symptoms
Tumbles but no heat; dryer won't start; long dry times; loud squealing or rumbling; drum stops or won't turn.
Common Causes
- Restricted venting or clogged lint trap causing overheating and thermal fuse failure
- Failed thermal fuse, heating element, or thermostats
- Worn drive belt, drum rollers, or idler pulley causing no tumble or noise

Helpful Repair Tip
If the dryer tumbles but won't heat, first check the thermal fuse for continuity—it's quick and inexpensive. If it's blown, replace the fuse and clean the vent; a blown fuse usually indicates restricted airflow.
Frequently Asked Questions
Why does my WED5050LW0 tumble but not heat?
Most commonly a blown thermal fuse, failed heating element, or an open thermostat. First check venting for blockages (restricted airflow often causes the fuse to blow). Then unplug the dryer and test the thermal fuse and heating element for continuity—replace any open parts.
Can I replace the thermal fuse or heating element myself?
Yes, if you are comfortable unplugging the dryer, removing access panels, and using a multimeter. Always disconnect power first. Replacing the thermal fuse and heating element is a common DIY repair, but if you need to test voltage at the terminal block or replace the motor, consider hiring a qualified technician.
