Dryer Faulty Door Latch or Switch
Dryer won't start at all (no hum), or it starts and stops the moment you nudge the door — the door no longer clicks shut firmly
70% chance this is caused by:
Broken latch strike or failed door-switch — the dryer's safety interlock no longer signals the door is closed
Dryer faulty door latch or switch is an easy-difficulty repair. The most likely cause is broken latch strike or failed door-switch — the dryer's safety interlock no longer signals the door is closed, and replacing the failed part takes approximately 20-30 minutes. The part costs about $23 — compared to $500-1,100 for a full replacement.
Fix it this weekend. Most parts ship same-day online.
A service call costs $150-300. This repair takes about 20-30 minutes and the part runs $23. Order the part tonight, fix it Saturday morning.

📋 Step-by-Step Instructions
Confirm the symptom pattern: no sound at all when you press start, or running stops instantly when the door moves. Both point at the door switch circuit, not the belt, motor, or thermal fuse.
Inspect the latch first — it is free. Close the door slowly and listen: it should click positively. Look at the strike (the small plastic tab on the door) and the catch on the cabinet. A cracked strike that no longer reaches the catch explains everything.
Test the switch circuit before buying parts: unplug the dryer, open the door, and find the switch plunger near the door opening. Press it by hand — you should hear a crisp click. No click, or a mushy one, means a dead switch.
With the dryer still unplugged, remove the two screws under the lint filter to release the top panel, then remove the front panel screws and lay the panel forward to reach the switch mounted behind the door opening.
Disconnect the switch wire harness and test the switch with a multimeter: it should read open (no continuity) with the plunger released and continuity with the plunger pressed. Any other reading means replace the switch.
Release the switch's mounting screw or clips, swap in the new switch, and reconnect the harness in the same positions. If the strike was cracked, unscrew it from the door and fit the new one.
Reassemble the panels, plug in, and test the interlock three ways: the dryer must NOT start with the door ajar, must start normally when closed, and must stop the instant you open the door mid-cycle. All three passing means the safety interlock is correct.
If the switch tests fine and the latch is intact but the dryer still won't start, the fault is further down the start circuit: check the start switch (the button itself), the drive motor, or the control board — the door switch is just the first link in that chain.
Don't put this off.
A Dryer that's failing can cause water damage, electrical issues, or food spoilage — each costing 10x what the replacement part costs. The fix is straightforward. The part is cheap. The risk of waiting isn't.
🔍 Why This Happens
Root cause analysis for your dryer's faulty door latch or switch
The door switch assembly in your dryer is an electro-mechanical component that fails through electrical arcing, contact pitting, or winding breakdown. These components typically fail after years of repeated switching cycles — the contacts degrade gradually until they stop making a reliable connection. At 70% match rate for your symptom, this is the component to replace.

🛡️ Prevention Tips
How to prevent your dryer's faulty door latch or switch from happening again after this repair.
Clean the lint screen before every single load. A clogged lint screen reduces airflow, makes the dryer work harder, and is a fire hazard.
Have the dryer vent duct cleaned or inspected annually. Lint accumulates inside the duct over time, restricting airflow and overheating components.
Don't overload the dryer. Heavy loads strain the drive belt, drum rollers, and motor — leading to premature mechanical failure.
Avoid running the dryer on the hottest setting unless necessary. High heat accelerates thermal fuse degradation and stresses the heating element.
Before installing the new door switch assembly, inspect the wiring connectors for corrosion, melting, or loose fits. Electrical failures often damage the connector, not just the component.
