🧩 Compatibility Notes
-
Confirm your appliance is a residential electric dryer and that the door switch specification (connector style, mounting bracket) matches your unit.
-
Some dryer models may use different switch assemblies (with different shapes or wire harnesses) — always compare the existing part visually and via model plate to ensure match.
-
Replacing the switch alone won’t fix issues caused by a faulty door hinge, misaligned door, or broken door latch mechanism. These should be checked concurrently.
-
Installation requires disconnecting power and ensuring correct wiring and secure mounting of the new switch — technician or qualified person recommended.
