What is the capacity of the wed5300sq0?
The Whirlpool WED5300SQ0 dryer is commonly listed as having about 6.5 cu. ft. of drum capacity, which is considered a large-capacity size for drying bulkier loads like towels, sheets, and blankets. For model-specific use and loading guidance, see the WED5300SQ0 user manual.
A “6.5 cu. ft.” drum can still dry poorly if airflow is restricted or the load is packed too tightly. For best results with this Whirlpool dryer:
- Load items loosely so they tumble freely (avoid packing the drum)
- Mix similar fabric weights together (heavy towels with heavy towels)
- Clean the lint screen before every load
- Use the correct cycle and temperature for the fabric
- Check that the exhaust vent is not crushed or kinked
These examples help you avoid overloading even with a large-capacity drum:
| Load type | Typical items | Tip |
|---|---|---|
| Towels | Bath towels, hand towels, washcloths | Dry towels together for even drying |
| Bedding | Sheets and pillowcases | Avoid stuffing comforters tight |
| Mixed everyday | Shirts, jeans, underwear | Keep weights similar |
Capacity affects drying performance, energy use, and wear on parts like the drum belt and motor. Overloading can increase strain and contribute to issues that sometimes lead customers to replace wear items such as the dryer drum belt 341241.

How do you know if a thermal fuse is blown on a whirlpool dryer?
On a Whirlpool WED5300SQ0 dryer, a blown thermal fuse is confirmed with a continuity test: with power disconnected, the fuse should read close to 0 ohms (continuity). If your meter shows OL or no continuity, the thermal fuse is blown and must be replaced.
Before testing, review the safety and access notes in the WED5300SQ0 user manual.
- Unplug the dryer (or switch off the breaker) before opening any panels.
- Access the thermal fuse (commonly on the blower housing on many Whirlpool designs).
- Pull the wire connectors off the fuse terminals (grab the connector, not the wire).
- Set your multimeter to continuity or the lowest ohms setting.
- Touch one probe to each terminal.
- Interpret the reading:
- 0 to a few ohms: fuse is good
- OL / infinite / no beep: fuse is blown
On this model, the compatible replacement is the dryer thermal fuse WP3392519. Replace the fuse; then correct the overheating cause so it does not blow again.
Common overheating causes to check:
- Lint screen clogged or coated with residue
- Exhaust vent crushed, kinked, or restricted
- Outside vent hood blocked
- Blower wheel damage or lint buildup in the blower housing
| Symptom | Often points to | Notes |
|---|---|---|
| Dryer runs but no heat | Heating circuit issue | Fuse can be one cause; also check airflow and thermostats |
| Dryer will not run | Safety circuit open | Some Whirlpool designs stop the motor when the fuse opens |
| Long dry times, very hot cabinet | Venting restriction | Fix venting before replacing parts |
The thermal fuse is a one-time safety device. When it opens, it is telling you the dryer likely overheated, often from poor airflow. Fixing the venting issue helps protect the heating element and thermostats and restores normal drying performance.

Why is my whirlpool dryer running but not heating?
If your Whirlpool dryer model WED5300SQ0 runs but doesn’t heat, the most common causes are a tripped breaker (the drum can still turn), an airflow restriction, or a failed heating circuit safety part such as a thermal fuse or thermal cut-off. Use the WED5300SQ0 dryer user manual troubleshooting steps to narrow it down.
- Confirm you did not select an Air/No Heat or low-heat setting.
- For electric dryers, reset the two-pole breaker (or replace both fuses if your home uses fuses).
- Clean the lint screen and check for strong airflow at the outside vent hood.
- Make sure the exhaust duct is not crushed, kinked, or clogged.
- Run a timed heat cycle for 5 minutes and check for heat at the drum.
If power and venting check out, these parts are frequent culprits on this model:
- Dryer thermal fuse WP3392519 (opens if the dryer overheats)
- Dryer thermal cut-off fuse kit 279816 (safety cut-off in the heater circuit)
- Dryer high-limit thermostat WP3977767 (limits heater temperature)
- Dryer operating thermostat WP3387134 (regulates normal cycling temperature)
- Heating element wiring issues; consider inspecting connections and using the correct dryer heating element wire kit 279457 if terminals are damaged
| What you notice | Most likely direction | Why |
|---|---|---|
| Drum turns, no heat at all | Power supply or safety fuse/cut-off | Heater circuit is interrupted |
| Heat comes and goes, long dry times | Venting restriction or thermostat issue | Overheating triggers cycling/safety |
| Dryer heats but clothes stay damp | Airflow problem | Heat can’t move moisture out |
A clogged vent can overheat the heater housing and repeatedly blow safety devices. Fixing airflow first helps prevent repeat failures and improves drying performance.
