How to Fix Honeywell Wi-Fi Thermostat Connection Failure E43

Fortunately, there are a few simple solutions that can help you quickly resolve this issue and get your thermostat back up and running. Here are a few tips:

1. Check Your Wi-Fi Settings

The first step is to make sure your Wi-Fi settings are correct. Make sure the Wi-Fi network name and password are correct, as this is the most common cause of connection errors. If you're unsure of your Wi-Fi settings, you can usually find them in the router's settings or by following the instructions in the manufacturer's manual.

2. Update the Firmware

If your Wi-Fi settings are correct and the connection is still failing, it's time to update the firmware. You can usually find the latest firmware update on the Honeywell website. Download the update and follow the instructions for installation. This should resolve the connection issue.

3. Check for Interference

Interference can also cause connection issues. Check for other devices that might be using the same frequency as your Wi-Fi router. Things like microwaves, cordless phones, or other electronics can cause interference and make it difficult for your Wi-Fi router to connect to your Honeywell Wi-Fi thermostat. If your router is close to any of these devices, move it away.

4. Reset the Thermostat

If none of the above steps work, it's time to reset the thermostat. Turn off the power to the thermostat and wait a few seconds before turning it back on. This will reset the thermostat and should resolve the connection issue.

5. Contact Honeywell

If you're still having trouble, contact Honeywell support. They can provide additional troubleshooting tips and help you get your thermostat back up and running.
