Riello Servomotor 3013936

The Riello servomotor 3013936 is a burner servomotor used across the Riello RS range of burners. It drives the air damper through its travel, positioning the damper for pre-purge, ignition and each firing rate. It is a service part for Riello burner spares.

• The burner locks out because the air damper does not reach its pre-purge or ignition position.
• The damper stays fixed at one position and does not move through the firing range.
• The servomotor buzzes, stalls or runs erratically instead of moving smoothly.
• The damper position is inconsistent between starts, giving unstable combustion.
• Visible damage, overheating or a burnt smell at the servomotor.

• Confirm your burner model and code against the fitment list above.
• Check the part number on the existing servomotor matches 3013936.
• Inspect the damper linkage and wiring before replacing, as a fault there can mimic a failed servomotor.
• Check the burner's technical documentation if your model or code is not shown in the list.
