Fix Samsung Dryer Won’t Turn Off After Door Open: 5 DIY Checks
Hey, it’s Master Tech Scott—JustAnswer-verified, 10+ years in the field, and Samsung Master Technician certified. I’ve been inside more Samsung dryers than most techs see in a lifetime (check my profile: https://www.justanswer.com/appliance/expert-mastertechscott/).
Today we’re tackling the Samsung dryer won’t turn off after opening door mid-cycle—a classic door-switch casualty that turns your laundry room into a fire hazard. You yanked the door open mid-spin, and now the drum keeps tumbling even with the door wide open. Unplugging didn’t reset it. Smart move stopping there—this is a legit fire risk. Let’s diagnose safely, swap the exact OEM part if needed, and know when to wave the white flag and call a pro.
Samsung dryers pack EcoBubble™ moisture sensing, SmartThings™ remote stop/start, and MultiSteam™ wrinkle release—but none of that matters if the door switch fails and the heater stays live. Let’s fix it.
Why This Happens 9 Times Out of 10
The door switch (DC64-00828A) is a $22 plastic plunger that tells the control board “door closed = run, door open = stop everything.” When you pop the door mid-cycle, the plunger can:
- Snap internally (common on DVE45/DVE50 series)
- Burn contacts from arcing
- Get jammed by lint or a bent strike
Result? Drum + heater stay on → fire hazard. I’ve seen melted wiring and scorched cabinets from ignored “door open” runs.

5 DIY Checks to Fix Samsung Dryer Won’t Turn Off (Door Open)
SAFETY FIRST: UNPLUG THE DRYER NOW. 240 V + lint = 🔥. Work in a well-lit, ventilated space. Gloves on.
- Visual Strike & Switch Inspection
Open the door. The door strike (plastic hook) should click firmly into the door switch (top-left of door frame). Bent strike? Replace DC61-02630A (RepairClinic.com).
Pro Tip: I’ve fixed 40% of “won’t stop” calls just by bending the strike back with pliers. - Plunger Actuation Test
With the unit unplugged, push the switch plunger by hand. It should click and spring back. Sticky or silent = bad.
Warning: Never bypass the switch with tape or wire—fire hazard! - Continuity Test on Door Switch
Remove top panel (two screws at back, slide forward). Unplug the switch harness. Set multimeter to continuity:- Door closed (plunger pushed): beep
- Door open (plunger out): no beep
No beep when closed? Replace DC64-00828A Door Switch (PartsSelect.com).
- Check for Burnt Wiring
Look for melted insulation on the switch harness. Smell burnt plastic? Stop DIY—call a tech. Control board damage is next. - Reset & Test
Plug in, start a timed dry cycle, open door within 10 seconds. Drum + light should stop instantly. Still running? Unplug and call a pro.

Wrap-Up: Stop the Spin, Save Your Home
Your Samsung dryer’s SmartThings™ and EcoBubble™ are useless if the door switch fails. A $22 part and 20 minutes can fix 80% of “won’t turn off” issues—but never ignore a fire hazard. Test the switch, replace if needed, and call a pro if wiring is toast.
