Understanding the Problem
This guide covers the most common problems owners see with Whirlpool dryers in the DV456EWHDWRAA family: not heating, won't start, noisy operation, and drum not turning. Follow these numbered diagnostic and repair steps to identify and fix the issue. Always disconnect power (and gas, for gas units) before you begin. 1) Confirm model and power type - Check the service tag (usually inside the door or on the rear panel) to confirm DV456EWHDWRAA and whether it's electric (240V) or gas. Many symptoms and components differ between gas and electric units. 2) Symptom: Dryer tumbles but does not heat (electric) - Tools: multimeter, screwdriver, nut driver. - Step A: Unplug dryer. Remove the rear panel or front access to reach the heating assembly. - Step B: Inspect lint buildup and venting. Clean lint screen, internal lint, and the exterior vent. Poor airflow often looks like long dry times. - Step C: Locate the thermal fuse (mounted on the blower housing). Test for continuity with a multimeter. If open (no continuity) the fuse is blown and must be replaced. - Step D: Test the heating element coils for continuity. If open, replace the element. Also check for element shorted to ground (continuity between element and casing) — if present, replace element. - Step E: Test thermostats (high-limit and cycling) for continuity. Replace any thermostat that shows open when cold. - Step F: Verify the dryer is receiving proper voltage (240V) at the terminal block (electric only) — one person should measure; if you are not comfortable with live voltage work, call a pro. 3) Symptom: Dryer tumbles but does not heat (gas) - Step A: Verify the gas supply and the house gas shutoff is open. - Step B: Check the igniter/ignition system: if the igniter is cracked or does not glow, the igniter assembly may be bad. Test continuity per service manual and inspect for visible damage. - Step C: Test the thermal fuse and gas valve coils. A blown thermal fuse will prevent the gas valve from opening. 4) Symptom: Dryer will not start or does not tumble - Step A: Confirm door switch continuity — if door switch is faulty the dryer won't start. - Step B: Check the start switch and selector switches for continuity. - Step C: Inspect the drive belt — if broken the drum will not turn though motor may run. Replace broken belt. - Step D: If motor hums but does not start, inspect motor start capacitor, motor windings, and idler pulley. Replace the motor if it fails continuity or is noisy/locked. 5) Symptom: Loud noise, squealing, or scraping - Step A: Remove front or rear panel and spin the drum by hand. Listen for bearing or roller noise. - Step B: Replace worn drum rollers, glides, or bearings (depending on model). Check the idler pulley for worn bearing and the motor for worn bearings. 6) General step-by-step replacement approach (example: thermal fuse) - Unplug the dryer or shut off power at the breaker. - Pull dryer away from wall and remove the appropriate access panel. - Locate and note wiring orientation of the failed part; take a photo. - Remove the connector(s) and fastener(s) holding the component. - Install new part, reconnect wires, reassemble panels, restore power and test. 7) Final verification - Run a timed cycle and confirm heating, tumbling, and airflow are normal. Check exhaust vent at the outside hood to confirm proper airflow. Safety note: Always disconnect power before opening the dryer. When testing live voltage or gas components, if you are not experienced or comfortable, hire a qualified appliance technician. Replacement parts must match your exact model — verify the part number on your dryer tag before ordering.
Common Symptoms
No heat but tumbles, long dry times, dryer won't start, loud scraping/squealing noises, burning smell, tripping breakers.
Common Causes
- Clogged lint screen or external vent reducing airflow
- Blown thermal fuse or failed thermostat/heating element (electric) or failed igniter/gas valve (gas)
- Broken drive belt, failed motor, or faulty door/start switch
- Worn drum rollers, idler pulley, or bearings causing noise

Helpful Repair Tip
To quickly confirm a blown thermal fuse: remove power, disconnect the fuse and check it with a multimeter for continuity; an open fuse is almost always the cause of no-heat but normal tumbling.
Frequently Asked Questions
How do I tell if my DV456EWHDWRAA is gas or electric?
Check the service tag (inside the door opening or on the back panel) for model and power type. An electric dryer will have a 240V cord/terminal block and no gas line; a gas dryer will have a gas inlet/stub and typically a standard 120V plug for controls. If unsure, pull the dryer away from the wall and look for a gas flex line connection or the large 240V cord.
Can I replace the thermal fuse or heating element myself?
Yes — these are commonly user-replaceable with basic tools: unplug the dryer, remove the access panel, note wiring locations (take a photo), disconnect the old component, and install the replacement. Always verify the replacement part matches your exact model. If the cause is a shorted heating element or wiring fault, troubleshoot fully before replacing the fuse again. If you're uncomfortable working on electrical or gas components, hire a qualified technician.
