Introduction
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.
What you need
-
Step 2 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.
-
-
Step 3 Remove the rear panel
-
Pull the sheet metal rear panel straight off the dryer.
-
-
Step 4 Locate the thermal fuse and inspect for lint buildup
-
Locate the thermal fuse mounted on the blower housing.
-
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.
-
-
Step 5 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.
-
-
Step 6 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.
-
-
Step 7 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.
-
Tighten all screws once the panel is aligned.
-
-
Step 8 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.

Ask FixBot
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?
