Your Control4 smart home system is designed for reliability and seamless automation. However, like any network-based system, occasional issues can occur due to power interruptions, network instability, or device communication errors.

Before submitting a support request, please work through the troubleshooting steps below. Many common issues can be resolved in just a few minutes.

Step 1 – Perform a System Reboot (Most Common Fix)

A simple reboot resolves the majority of Control4 system issues.

Reboot the Control4 Controller:

1. Locate your main Control4 controller (typically installed in a rack, media cabinet, or network area).

2. Unplug the power cable.

3. Wait 60 seconds.

4. Plug it back in.

5. Allow 5–10 minutes for the system to fully restart.

⚠️ During this time, touchscreens and apps may appear offline. This is normal.

Step 2 – Check Your Network

Control4 relies heavily on a stable local network.

Please confirm:

• Your internet service is working.

• Your Wi-Fi network is online.

• Your router and network switches have power.

• You are connected to your main network, not a guest Wi-Fi network.

• No recent changes were made to your ISP equipment or Wi-Fi password.

If devices are intermittently disconnecting:

Reboot your:

• Modem

• Router

• Network switches

• Wireless access points

Allow 5–10 minutes after rebooting networking equipment.

Step 3 – Mobile App Not Connecting

If your Control4 app will not connect:

1. Confirm your phone/tablet is connected to your main Wi-Fi network.

2. Close and reopen the app.

3. Log out and back in.

4. If necessary, delete and reinstall the Control4 app.

5. Ensure you are not connected to a VPN.

If accessing remotely:

• Confirm your internet is active.

• Confirm your Control4 remote access subscription is active (if applicable).

Step 4 – One Room or Device Not Responding

If only one room or device is affected:

• Confirm the device has power.

• Check HDMI or AV cabling.

• Verify the correct input/source is selected.

• Power cycle the individual device (TV, cable box, receiver, etc.).

• If it is a touchscreen, check Wi-Fi connection.

If audio is missing:

• Confirm volume levels.

• Ensure the correct audio zone is selected.

• Verify amplifiers have power.

Step 5 – Lighting or Keypad Issues

If lights are not responding:

• Confirm the circuit breaker has not tripped.

• Check that the keypad LEDs are illuminated.

• Try toggling the light manually at the keypad.

If a keypad is completely unresponsive, it may require service.

Step 6 – After a Power Outage

Following a power outage:

• Wait 10–15 minutes for all equipment to fully boot.

• If the system does not restore properly, reboot the controller and network equipment.

• Confirm internet service has been restored by your provider.

When to Contact Support

Please submit a service request if:

• The system does not respond after rebooting.

• Devices remain offline.

• Touchscreens will not reconnect.

• Automation events are no longer triggering.

• You recently changed internet providers or networking equipment.

• You require programming changes or system upgrades.

When contacting support, please include:

• Description of the issue

• Rooms or devices affected

• When the issue started

• Whether any network or ISP changes were made

• Whether you have completed the troubleshooting steps above

This helps us resolve your issue faster and may prevent a service visit.

Important Notes

• Control4 systems are network-dependent. Many issues originate from router or Wi-Fi instability.

• Changing your ISP equipment, Wi-Fi name, or password may require reconfiguration.

• Some service calls may be billable if the issue is related to third-party equipment or networking not originally installed by us.

If you are unsure at any step, please contact our support team — we are happy to help.
