9. Troubleshooting
If you experience issues with your YeloDeer thermostat, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater not turning on | No power to thermostat; Incorrect wiring; Temperature set too low. | Check circuit breaker; Verify wiring connections; Increase temperature setting. |
| Inaccurate temperature reading/control | Thermostat location (drafts, direct sunlight); Sensor obstruction. | Ensure thermostat is not in direct drafts or sunlight. Clear any obstructions around the sensor. Note that electronic thermostats are generally more accurate than older mechanical types, but minor variations can occur. |
| Thermostat indicator lights not working | No power to thermostat; Faulty unit. | Check power supply and wiring. If power is confirmed and lights still don't work, contact support. |
