If your Samsung SmartThings dryer remote start is not working, the cause is usually a setting, connection, or cycle requirement rather than a hardware failure.
This guide walks through the most common fixes so you can get remote drying working again without guesswork.
Why Samsung SmartThings Dryer Remote Start Stops Working
Samsung dryers with SmartThings support depend on a chain of conditions before remote start is allowed: the dryer must be paired correctly, connected to Wi-Fi, in the right mode, and not blocked by safety or cycle restrictions.
When any one of those links breaks, the remote start command will fail or appear unavailable in the app.
In most homes, the issue is caused by one of these factors:
- the dryer is not in Remote Start mode
- the SmartThings app lost the device connection
- the dryer is on a cycle that does not support remote starting
- Wi-Fi or router settings changed
- child lock, control lock, or door conditions are preventing startup
Check the Dryer’s Remote Start Requirement First
Samsung dryers typically require you to enable remote control at the appliance before SmartThings can start a cycle.
This is different from simply opening the app and tapping start.
On many models, the dryer must be powered on and placed into a remote-enabled state from the control panel.
What to verify on the dryer
- Press the Power button on the dryer
- Confirm the dryer door is fully closed
- Look for a Remote Start, Smart Control, or similar indicator
- Make sure Child Lock or Control Lock is off
- Check whether the dryer display shows it is ready for remote operation
If the dryer is not in a remote-ready state, the SmartThings app may show the appliance online but still refuse to start it.
Make Sure the Cycle Supports Remote Start
Not every cycle or setting allows remote initiation.
Samsung dryers may block remote start if the selected cycle requires a manual action, special dry setting, or immediate door interaction.
Some models also restrict remote use after the cycle has already begun or when a custom option is incompatible with app control.
If you suspect a cycle issue, try a simple standard cycle such as Normal or Timed Dry with default settings.
If that works, the problem is likely tied to one specific cycle option rather than SmartThings itself.
Common cycle-related blockers
- nonstandard or specialty cycles
- heavy custom modifications to temperature or dryness
- wrinkle-care or delay features that conflict with remote launch
- cycles that require local confirmation before starting
Confirm SmartThings App and Dryer Pairing
A pairing problem can make the dryer appear in SmartThings without actually accepting remote commands.
If the connection is stale, incomplete, or signed into the wrong Samsung account, remote start may stop responding.
Open the SmartThings app and check that the dryer is listed under the correct home and room.
If the device shows offline, delayed, or unavailable, the issue is likely connection-related.
Steps to refresh the pairing
- Open SmartThings and select the dryer device card
- Check whether the app reports the dryer as online
- Turn the dryer off and on again from the control panel
- Force close and reopen the SmartThings app
- Sign out and back into the Samsung account if needed
- Remove and re-add the dryer only if simpler refresh steps fail
If you re-add the appliance, make sure to complete the full setup process and grant the permissions needed for remote control.
Verify Wi-Fi and Router Conditions
Samsung SmartThings appliances rely on a stable Wi-Fi connection.
A network change, weak signal, band steering issue, or router restart can interrupt remote start even when the dryer still appears in the app.
Most Samsung appliances work best on a stable 2.4 GHz Wi-Fi connection.
If your router recently changed names, passwords, security settings, or channel behavior, the dryer may need to be reconnected.
Wi-Fi checks that matter most
- confirm the dryer is connected to the correct home Wi-Fi
- ensure the router is broadcasting a strong 2.4 GHz signal near the laundry area
- restart the router and modem if the network has been unstable
- avoid guest networks or enterprise-style login networks
- check whether the router blocked the appliance after a password change
For homes with mesh Wi-Fi, make sure the dryer did not switch to a weak node or lose connection after a firmware update.
Look for Control Lock, Child Lock, or Safety Interlocks
Safety features can silently stop remote start.
Samsung dryers often require the door to be closed, controls to be unlocked, and the appliance to be in a safe idle condition before accepting a remote command.
If the control panel is locked, the dryer may ignore app commands even though the SmartThings app looks normal.
Similarly, if the door sensor does not register a secure close, the dryer will reject the command for safety reasons.
What to check on the appliance
- disable Child Lock or Control Lock
- press the door firmly until it latches cleanly
- inspect the door seal for lint, clothing, or obstructions
- verify that the cycle is not paused or waiting for a local input
Update SmartThings, the Dryer Firmware, and Your Phone
App and firmware mismatches can cause remote features to fail.
SmartThings regularly receives updates that improve device control, and Samsung appliance firmware updates can fix connectivity bugs or command-handling problems.
Check for updates in three places: the SmartThings app, your phone’s operating system, and the dryer’s available firmware or device update menu inside SmartThings.
If the app is outdated or the appliance firmware is behind, remote start may behave unpredictably.
Update checklist
- update the SmartThings app from the App Store or Google Play
- install phone OS updates if pending
- open the dryer device page in SmartThings and look for firmware update prompts
- restart the phone after updates if the device still fails to respond
Test the Dryer With a Simple Remote Start Attempt
Once the settings look correct, run a simple test instead of a full load.
Use a basic cycle, confirm the dryer is powered on locally, and attempt remote start from SmartThings within a few minutes.
This helps isolate the issue.
If a simple test works, your earlier failure was likely caused by cycle settings, stale app data, or a temporary network dropout.
If the test still fails, the problem is more likely related to device pairing, Wi-Fi stability, or the dryer’s remote mode status.
When the Dryer Shows Online but Won’t Start
It is common for SmartThings to show the dryer as online while remote start still fails.
That usually means the appliance can communicate with the cloud but is not accepting start commands because a local requirement has not been met.
Common reasons include:
- the dryer is not in remote mode
- the cycle is incompatible
- the door is open or not fully latched
- a lock feature is enabled
- the appliance needs a power cycle to clear a stale state
If the problem persists, unplug the dryer for a short reset, wait about one minute, then reconnect power and test again.
A brief reset can clear temporary command errors without affecting settings on many models.
When to Reconnect or Reset the Device
If you have already checked remote mode, Wi-Fi, locks, and updates, it may be time to reconnect the dryer inside SmartThings.
This is often the best next step after a network change or app migration.
Use a device reset only when the appliance repeatedly goes offline, loses settings, or fails to accept commands after multiple verified checks.
Reconnection is usually safer and faster than a full factory reset.
Try a reconnect if
- your router name or password changed
- the dryer was moved to a new room or home in SmartThings
- the app shows the device as connected but unresponsive
- you signed into a different Samsung account on a new phone
Prevent Future Remote Start Problems
Once remote start is working again, a few habits can keep it stable.
Keep the dryer on the same Wi-Fi network, avoid frequent router changes, and verify remote mode before relying on the app.
It also helps to keep SmartThings and the appliance firmware current so fixes and compatibility improvements stay in place.
For the most reliable setup, remember these best practices:
- keep the dryer on a strong 2.4 GHz Wi-Fi signal
- leave the SmartThings app updated
- use standard cycles when testing remote start
- check for control lock after power interruptions
- confirm the appliance is in remote-ready mode before leaving home
When Samsung SmartThings dryer remote start is not working, the fix is usually found by moving through the appliance settings, the app connection, and the home network in that order.
That approach solves most cases quickly and helps you avoid unnecessary resets or service calls.
