Understanding the Problem
The Whirlpool WED5500BW0 is a common electric dryer model. Typical service issues are: no heat or weak heat, dryer won't start, long drying times, loud noises (squeal/grind), and the drum not tumbling. Below are practical diagnostic and repair steps for each symptom so you can target the faulty part and fix it yourself. 1) Dryer Not Heating or Weak Heat 1.1 Inspect venting: Remove the exhaust hose and check for lint blockage. Poor venting often causes long dry times or weak/no heat. Clean the lint in the lint trap and inside the cabinet at the lint chute. 1.2 Check house circuit: Verify the dryer is on a 240V circuit (two hot legs). A missing leg will run the motor but not heat. Use a multimeter at the terminal block to confirm ~240V across the two hot terminals. 1.3 Test the thermal fuse: Locate the thermal fuse (on the blower housing). Unplug dryer, remove rear panel or front access to reach it. Disconnect wires and test continuity with a multimeter. If open/no continuity, replace the thermal fuse. 1.4 Test heating element and thermostats: With power off, disconnect the heating element assembly and test for continuity. Also test high-limit thermostat and cycling thermostat for continuity. Replace any component that has no continuity. 1.5 Replace/repair: If venting and power are good but heating elements or thermostats are open, replace the faulty parts. Reassemble and test. 2) Dryer Won't Start (no drum movement, no motor noise) 2.1 Check power: Confirm 240V supply and that the dryer is properly plugged in. 2.2 Door switch: With the door closed, use a multimeter to check door switch continuity. Replace if faulty. 2.3 Start switch / control board: Test the start switch for continuity when pressed. If switch is okay, inspect control board for burnt components or loose connectors. 2.4 Motor and belt: Remove the front or top to access the drum. Check the drive belt for breakage. If the belt is intact, try manually turning the drum — if motor hums but doesn't turn, the motor or start capacitor may be bad. Replace motor if it fails bench tests. 3) Drum Not Tumbling or Slipping 3.1 Belt check: Remove the front panel to inspect the belt. If broken or glazed, replace the drive belt. 3.2 Idler pulley and drum rollers: Inspect the idler pulley and drum rollers for wear or seizure. Replace noisy or seized rollers/pulley. 3.3 Motor: If belt and pulleys look good but motor doesn't turn under load, test motor for continuity and signs of failure. 4) Loud Noises (squeal, rumble, grinding) 4.1 Locate noise: Run the dryer empty and listen. Squeal during start often indicates worn drum rollers or idler pulley. Grinding often indicates motor bearing failure. 4.2 Inspect rollers/pulley: Remove drum and spin rollers/idler by hand. Replace any that are rough, have play, or are noisy. 4.3 Motor replacement: If noise originates from motor bearings, replace the motor assembly. 5) Long Dry Times or Overheating 5.1 Venting and lint: Clean vent, hose, and house exhaust. Restricted airflow causes long dry times and can overheat components. 5.2 Moisture sensor: If the dryer keeps running past dryness, test the moisture sensor bars (usually behind the lint trap) for contamination; clean with rubbing alcohol. If readings are wrong, the sensor or control board may be faulty. Basic step-by-step replacement example — Thermal Fuse A. Unplug the dryer and pull it away from the wall. B. Remove the rear panel (or front, depending on layout) to access the blower housing. C. Locate the thermal fuse (small rectangular component with two wires on the blower housing). D. Take a photo of wiring, disconnect the wires, and remove the mounting screw. E. Install the new fuse, reconnect wires, reassemble panels, plug in and test. Safety note: Always unplug the dryer or shut off the breaker before accessing interior components. If you are uncomfortable with electrical testing or disassembly, call a qualified technician.
Common Symptoms
No heat or weak heat, won't start or no motor action, drum won't spin, long dry cycles, loud squealing or grinding noises.
Common Causes
- Clogged venting or lint trap reducing airflow
- Failed thermal fuse, heating element, or thermostats
- Broken drive belt, worn drum rollers, or seized idler pulley
- Faulty motor or start components
- Power supply issue (lost 1 leg of the 240V circuit) or bad door switch

Helpful Repair Tip
If the dryer runs but doesn't heat, first confirm you have 240V across the two hot terminals at the wall outlet — this quickly separates power/feed problems from internal heating-component failures.
Frequently Asked Questions
Is the WED5500BW0 an electric or gas dryer?
WED5500BW0 is an electric dryer model. It uses an electric heating element and requires a 240V supply (two hot legs).
How do I test the thermal fuse on this dryer?
Unplug the dryer and locate the thermal fuse on the blower housing. Disconnect its wires and use a multimeter set to continuity/ohms. A good fuse will show near 0 ohms continuity; an open reading means the fuse is blown and must be replaced. Replace with the same type/spec and address the cause (venting/overheating) before reassembly.
