If a Whirlpool dryer has power but won’t start when you press the button, a blown thermal fuse is a common cause. This guide shows how to disconnect power, remove the rear panel, swap the thermal fuse on the blower housing, and reassemble the dryer. Cleaning lint buildup while you’re in there can help prevent the new fuse from failing again.

ШагиSteps

Disconnect power

Unplug the dryer’s power cord from the outlet, or turn off the dryer’s breaker.
WARNING: Don’t work on the dryer while it’s plugged in, because the rear panel exposes electrical components.

Remove the rear-panel screws

Use a 1/4 inch hex-head screwdriver, nut driver, or socket to remove the screws securing the rear panel.
Remove nine to 10 screws, depending on the model.
Set the screws aside where they will not roll away.

Remove the rear panel

Pull the sheet metal rear panel straight off the dryer.
Caution: Sheet metal edges can be sharp, so wear gloves and handle the panel carefully.

Locate the thermal fuse and inspect for lint buildup

Locate the thermal fuse mounted on the blower housing.
The thermal fuse is an emergency shutoff that opens if the dryer gets too hot.
Inspect the blower housing area for excess lint buildup.
If a cover blocks access, remove the three to four screws holding the cover, then clean out any lint you can reach.

Transfer the wires to the new fuse

Pull the terminals off the old thermal fuse.
Install the wires onto the replacement thermal fuse in the same positions so you do not have to guess later.
Take a quick photo before removing anything if you want a reference.

Replace the thermal fuse

Use a 1/4 inch hex-head screwdriver to remove the screw securing the old thermal fuse, then remove the fuse.
Insert the new thermal fuse into position, making sure the lip seats properly.
Press the fuse down slightly, then reinstall the screw to secure it.

Reinstall the rear panel

Position the rear panel on the dryer.
Reinstall the nine to 10 rear-panel screws with a 1/4 inch hex-head screwdriver.
Do not tighten the first screw very far until the panel holes are aligned and all screws are started.
Tighten all screws once the panel is aligned.

Restore power and test the dryer

Plug the dryer back in, or turn the breaker back on.
If the dryer still will not start, stop and check for vent restrictions or other failed components before repeatedly replacing fuses.

Lint buildup and restricted venting can overheat the dryer and cause thermal fuse failures. Clean lint from the blower housing area you accessed, and inspect the vent path inside the machine and at the wall exhaust so heat and lint can exit freely. Repair didn't go as planned?
