Valor Boiler Sensor 5130291

The Valor 5130291 is a boiler sensor supplied as a replacement component for Valor heating appliances. It monitors temperature at its mounting point and feeds that reading back to the boiler's control board, which uses the signal to regulate firing and protect the appliance from overheating or unsafe operating conditions. The part carries the manufacturer code 5130291 and the alternative reference 1147217.

• The boiler locks out or shuts down shortly after ignition
• Fault codes relating to temperature sensing or flow/return temperature appear on the display
• The appliance runs erratically, cycling on and off more often than normal
• Domestic hot water or heating output becomes inconsistent
• The sensor body, wiring or connector shows heat damage, corrosion or a loose fit

• Check the manufacturer code 5130291 against the data plate and parts list for your specific Valor model
• Note any fault code stored in the boiler before removing the existing sensor, as it helps confirm the diagnosis
• Inspect the sensor seal or O-ring at the mounting point and replace it if it is perished or deformed
