Whirlpool WED5720RR0 electric dryer Parts

Yes. A 7.3 cubic foot dryer is considered a large-capacity size, so it has enough drum space for bulky items (like comforters) and bigger mixed loads. For a Whirlpool electric dryer like model WED5720RR0, that capacity typically means fewer loads and less overdrying from crowding.

What “7.3 cu. ft.” means in real use

A larger drum helps clothes tumble more freely, which improves airflow and drying performance.

• Fits bulky items more comfortably (comforters, blankets, winter coats)
• Handles larger family loads with fewer cycles
• Reduces wrinkling compared with stuffing a smaller drum
• Helps moisture escape faster because items can separate and tumble
• Works best when you still avoid overloading (leave some tumble room)

Capacity quick guide

These ranges are typical for full-size residential dryers.

Dryer capacity	Common label	Best for
5.0 to 6.0 cu. ft.	Standard	Singles, couples, smaller loads
6.1 to 7.0 cu. ft.	Large	Regular family laundry
7.1 cu. ft. and up	Extra-large	Bulky items and heavy weekly loads

Why it matters

When a dryer is too small for your load size, clothes pack together and block airflow. That can cause long dry times, higher energy use, and extra heat stress on components like the heater and thermostats.

Tips to get the best results from a large-capacity dryer

• Clean the lint screen before every load
• Use the right cycle (timed dry for consistent loads, sensor cycles for mixed loads)
• Avoid packing the drum tight; large capacity still needs tumbling space
• If dry times are long, check venting for restrictions and lint buildup
• If the dryer runs but won’t heat, follow an electric-dryer heat diagnosis like electric dryer wont heat troubleshooting video

The most common issues we see on the Whirlpool WED5720RR0 electric dryer are no heat or weak heat, long dry times from restricted airflow, loud rumbling or squealing from worn drum support parts, and a drum that will not turn due to a belt or idler problem.

Common symptoms and what usually causes them

• No heat: failed heating circuit component such as the thermal fuse W10909685 or a heater-related safety device
• Long dry times: lint buildup in the lint duct or exhaust duct, crushed vent, or a weak blower wheel
• Loud thumping/rumbling: worn drum rollers such as the dryer drum support roller WPW10314173
• Squealing: worn idler pulley or idler spring
• Drum will not tumble: belt/idler issue, motor problem, or a seized drum roller
• Overheating or shutting off: airflow restriction or a thermostat/thermal cut-off opening

Quick checks we recommend first

1. Clean the lint screen and confirm strong airflow at the outside vent.
2. Inspect the vent path for kinks, long runs, or heavy lint.
3. Listen for the noise type:
   • Thump/rumble often points to rollers
   • High-pitched squeal often points to the idler pulley
4. If the dryer runs but does not heat, test safety fuses and thermostats with a meter.
5. If the dryer is dead or stops mid-cycle, check the thermal fuse and door switch.

Parts that commonly fix these problems

Symptom	Commonly involved part	Example from this model’s parts
No heat	Thermal fuse	Thermal fuse W10909685
Rumbling/thumping	Drum support roller	Dryer drum support roller WPW10314173
Squealing or no tumble	Idler pulley	Dryer idler pulley (listed for this model)
Long dry times	Blower wheel or ducting	Dryer blower wheel, lint duct, exhaust duct

Why it matters

Airflow and heat problems can trigger thermal safety devices, increase dry times, and overwork the heating element and motor. Fixing venting and worn drum support parts helps the WED5720RR0 dry faster, run quieter, and avoid repeat failures.

Most Whirlpool dryers, including the Whirlpool WED5720RR0 electric dryer, typically last 10 to 13 years with normal household use. With consistent airflow maintenance and timely replacement of wear parts, it’s common for a dryer to reach about 15 years.

Typical lifespan and what affects it

A dryer’s life is mostly determined by heat stress, airflow restriction, and mechanical wear.

• Vent and lint buildup (restricted airflow overheats components)
• Load size and frequency (heavy, daily use shortens life)
• Heat setting habits (high heat all the time increases wear)
• Wear parts condition (rollers, idler pulley, blower wheel)
• Electrical health (stable power and good connections reduce failures)

Maintenance that extends dryer life

These habits reduce overheating and mechanical strain, which are the two biggest dryer killers.

• Clean the lint screen every load
• Check airflow at the outside vent hood; strong flow matters
• Clean the vent duct at least once a year (more often with long runs)
• Avoid overloading; keep loads loose so air can move
• Stop using the dryer if you hear persistent squealing or thumping; replace wear parts early

Parts that commonly wear out first (and why)

If your WED5720RR0 is noisy, slow to dry, or overheating, these parts are frequent culprits.

Symptom	Common cause	Example part for this model
Squealing, rumbling	Drum support wear	Dryer drum support roller WPW10314173
Squealing, belt slack	Idler pulley wear	Dryer idler pulley W10837240
No heat or overheating shutdown	Heat safety opens	Thermal fuse W10909685
Poor airflow, long dry times	Blower damage or lint load	Dryer blower wheel WP697772

Why it matters

Knowing the average lifespan helps you decide whether to repair or refresh key components. On a dryer in the 10 to 13 year range, replacing common wear items can restore performance and help prevent secondary damage from overheating or vibration.
