The thermostat frequently loses its Wi-Fi connection or cannot maintain a connection to the Carrier app.

Safety first: No electrical work on HVAC is required.

• Step 1 – Check signal strength: On the thermostat Wi‑Fi settings, check signal strength. If low, move the router closer or install a Wi‑Fi extender.
• Step 2 – Change router channel: Log into your router and change the 2.4 GHz channel to a less congested one (e.g., 1, 6, or 11).
• Step 3 – Update router firmware: Ensure your router is running the latest firmware from the manufacturer.
• Step 4 – Re-add thermostat to app: Remove the thermostat from the Carrier app and re-add it following the pairing instructions.
• Step 5 – Replace thermostat if needed: If other devices are stable but the thermostat continues to drop connection, its Wi‑Fi module may be failing.
