Understanding these common issues is the first step towards effective troubleshooting and restoring reliable climate control within your RV.
Erroneous Temperature Readings
Inaccurate temperature readings are a prevalent issue with Furrion thermostats, especially the FACW12SA-BL model. The root cause often lies in the temperature sensor’s location – typically within the ceiling’s air distribution box. This placement doesn’t accurately reflect the ambient temperature experienced in the living space.
When the air conditioner operates, maintaining a low fan speed is crucial. This ensures interior air is consistently drawn into the distribution box, providing a more representative temperature reading for the sensor. Without adequate airflow, the sensor measures the temperature of the air within the duct, which can be significantly different from the cabin temperature.
Grand Design RV owners have found that relocating the temperature sensor closer to the thermostat resolves this issue, providing more consistent and accurate climate control.
The Role of the Room Sensor Wire
The “ROOM SENSOR” wire is critical for accurate temperature regulation with your Furrion thermostat. This wire connects the thermostat to a temperature sensor, typically located within the air conditioning ductwork. It’s essential to differentiate this wire from the “FREEZE SENSOR” wire, which serves a different purpose – protecting the unit from freezing temperatures.
The ROOM SENSOR provides the thermostat with feedback on the actual ambient temperature in the RV. Without a properly functioning connection or a correctly positioned sensor, the thermostat will rely on potentially inaccurate readings, leading to inconsistent heating or cooling.
Identifying this wire during troubleshooting is key. Look for a wire labeled “ROOM SENSOR” when accessing the wiring within the air distribution box. Proper function of this wire is vital for optimal performance.
Temperature Sensor Location & Airflow
Furrion FACW12SA-BL thermostats often experience inaccurate readings due to the temperature sensor’s location. Typically, the sensor resides within the air distribution box in the ceiling, not in the living space. This placement can lead to the sensor measuring the temperature of the air within the duct, rather than the room’s ambient temperature.
Airflow is crucial for accurate readings. When using the air conditioner, ensure the fan operates, even on a low setting. This draws interior air into the distribution box, allowing the sensor to measure a more representative temperature. Insufficient airflow results in the sensor reading stagnant, potentially warmer air.
Understanding this location and the importance of airflow is key to troubleshooting temperature discrepancies and achieving consistent climate control within your RV.
Troubleshooting Temperature Inaccuracies
Addressing inaccurate temperature readings on your Furrion FACW12SA-BL thermostat begins with verifying airflow to the temperature sensor. Ensure the AC fan runs continuously, even on low, to circulate room air into the air distribution box. If issues persist, consider the sensor’s location – it’s within the ductwork, not the living area.
Grand Design RV owners have successfully resolved this by relocating the sensor closer to the thermostat using dedicated kits. These kits position the sensor to measure ambient room temperature more effectively. Before attempting relocation, carefully identify the “ROOM SENSOR” wire (distinct from the “FREEZE SENSOR” wire) during inspection.
If wiring seems correct and the problem continues, contact Furrion support to explore warranty options or potential thermostat replacement.
Maintaining Airflow for Accurate Readings
Consistent and adequate airflow is crucial for accurate temperature readings with your Furrion thermostat, particularly the FACW12SA-BL model. The temperature sensor resides within the air distribution box, requiring a constant flow of air to register the cabin’s temperature correctly.
Always operate the air conditioner fan, even at its lowest setting, to ensure continuous air circulation. This prevents the sensor from measuring stagnant air within the ductwork, which can lead to significant temperature discrepancies.
Regularly check air filters for blockage, as restricted airflow directly impacts the sensor’s ability to provide accurate data. A clean filter promotes optimal air movement, contributing to reliable temperature control and overall system efficiency. Prioritizing airflow is a simple yet effective troubleshooting step.
Relocating the Temperature Sensor
A common solution for inaccurate temperature readings with Furrion thermostats, especially in Grand Design RVs, involves relocating the temperature sensor. The factory placement within the ceiling’s air distribution box often results in readings that don’t reflect the cabin’s actual temperature.
Grand Design RV owners have successfully addressed this issue by utilizing relocation kits to position the sensor on the wall, closer to the thermostat itself. This ensures the thermostat measures the temperature in the living space, improving temperature regulation and comfort.
Carefully identify the “ROOM SENSOR” wire (distinct from the “FREEZE SENSOR” wire) when relocating. While Furrion’s official stance may void warranties, Grand Design RV has confirmed support for installations using their provided kits.
