Instruccions d'instal·lació
Abans de la instal·lació
- Ensure the replacement sensor matches the specifications of the original part.
- Gather necessary tools, which may include screwdrivers, wrenches, and wire strippers.
- Familiarize yourself with the appliance's wiring diagram.
Passos d'instal·lació
- Desconnecteu l'alimentació: Turn off the main power supply to the heating appliance at the circuit breaker or fuse box. Verify power is off using a voltage provador.
- Sensor d'accés: Locate the existing flame sensor within the burner assembly. This typically involves removing an access panel.
- Treure el sensor antic: Carefully disconnect the wire from the old sensor and unmount it from its position. Note its orientation and depth within the flame path.
- Instal·leu un sensor nou: Mount the new Robertshaw 10-760 flame sensor in the same position and orientation as the old one. Ensure the probe extends into the flame path correctly.
- Connecteu el cablejat: Connect the 1/4-inch female spade terminal of the new sensor to the corresponding wire from the control board. Ensure a secure connection.
- Components segurs: Re-secure any removed panels or covers.
- Restaura l'alimentació: Torneu a engegar l'alimentació principal.
- Prova de funcionament: Initiate a heating cycle and observe the burner. The flame should ignite and remain lit. If the burner cycles on and off rapidly (short cycling), refer to the troubleshooting section.
Funcionament
The Robertshaw Universal Flame Sensor operates on the principle of flame rectification. When a flame is present, it ionizes the air, allowing a small electrical current to flow through the sensor probe to ground. The control board detects this current, confirming the presence of a flame. This signal is crucial for the safe operation of the heating appliance. If the control board does not detect a flame within a specified time after ignition, it will shut off the gas supply to prevent unburnt fuel accumulation, initiating a safety lockout.
The sensor itself is a passive component; its proper function is integrated into the overall control logic of the heating system. It does not actively generate a signal but rather completes a circuit when exposed to a flame.
Manteniment
Regular inspection and cleaning of the flame sensor are recommended to ensure reliable operation and prevent nuisance shutdowns. Perform maintenance at least once a year, or more frequently depending on appliance usage and environmental conditions.
- Desconnecteu l'alimentació: Always turn off the power to the appliance before performing any maintenance.
- Inspeccionar la sonda: Visually inspect the metallic probe for any signs of carbon buildup, corrosion, or physical damage.
- Neteja la sonda: If carbon deposits are present, gently clean the metallic probe with fine-grit sandpaper or steel wool. Avoid using harsh chemicals or abrasive cleaners that could damage the sensor. Do not bend the probe during cleaning.
- Check Insulator: Inspect the ceramic insulator for cracks or chips. A damaged insulator can cause a ground fault and prevent proper flame detection.
- Examineu el cablejat: Check the lead wire for any signs of fraying, cuts, or heat damage. Ensure the terminal connection is secure and free from corrosion.
- Remuntar i provar: After cleaning and inspection, reassemble the sensor and restore power. Test the appliance's operation to confirm proper flame detection.
Resolució de problemes
If your heating appliance is experiencing issues related to flame detection, consult the table below for common problems and solutions.
| Problema | Causa possible | Solució |
|---|---|---|
| Burner ignites, then shuts off rapidly (short cycling) | Dirty or faulty flame sensor; weak flame signal. | Clean the flame sensor probe. If the issue persists, replace the sensor. Ensure the flame is strong and consistent. |
| Appliance fails to ignite or locks out immediately | No flame signal detected; open circuit in sensor wiring. | Check all wiring connections to the sensor and control board. Ensure the sensor is properly positioned in the flame path. Test the sensor for continuity. |
| Intermittent operation or random shutdowns | Loose electrical connections; damaged lead wire; intermittent flame. | Secure all wiring connections. Inspect the lead wire for damage and replace if necessary. Verify consistent flame presence. |
| Sensor not detecting flame despite visible flame | Incorrect sensor positioning; ceramic insulator cracked. | Adjust the sensor's position to ensure the probe is fully immersed in the flame. Inspect the ceramic insulator for damage. |
