🧩 Compatibility Notes

Confirm the dryer uses a door switch assembly of this style (not a sensor or microswitch variant) before purchase.
-
Installation requires disconnecting power and accessing the top/front panel of the dryer — ensure technician or qualified person does the work.
-
If the door hinge or latch is damaged, simply replacing the switch may not fix the underlying problem; inspect the door mechanism too.
-
Always match the existing part visually and via model plate to ensure correct fit.
