Questions and answers
Showing fault on display and no ac
The fault display on a White Rodgers 1F85RF-275 thermostat indicates system issues using LED flash codes. Each code corresponds to a specific fault:
1. Code 1 (24 VAC lost) – Indicates loss of power. Possible cause: Power Mode Switch S7 set to RC and no common wire connected to C terminal.
Resolution: Check wiring and ensure common wire is connected properly.
2. Code 2 (Invalid packet) – Receiver detected a bad signal. Causes include poor antenna positioning, bad sensor location, noise, or interference.
Resolution: Reposition antenna or sensor, reduce interference. To override, press and hold RUN for 4 seconds (resets on power-up).
3. Code 3 (Unidentified packet) – Receiver not programmed to sensor or signal conflict with another device.
Resolution: Program (learn) receiver to the correct sensor.
4. Code 4 (No communication) – Thermostat failed to communicate with receiver.
Resolution: Check receiver installation or replace inoperative module.
5. Code 5 (Sensor not responding) – Indoor remote sensor failed.
Resolution: Check or replace the indoor sensor.
Always correct the highest priority error first; only one code is shown at a time.
