Riello Servomotor 3013395

The Riello servomotor 3013395 is a burner spare listed within the Riello burner spares range. It drives the moving components of the burner's air and fuel control assembly, such as the air damper or camshaft linkage, under the control of the burner control box. It is used across a number of Riello gas and oil burner models.

• The burner locks out or fails to start because the air damper is not moving to the correct position.
• The servomotor hums or buzzes but the linkage does not travel through its full stroke.
• The damper or camshaft linkage sticks, judders or moves erratically during the pre-purge or firing sequence.
• The motor runs hot, smells of burnt windings, or the casing shows signs of overheating.
• Repeated lockouts that clear after the linkage is moved by hand.

• Confirm your burner model and code against the fit list above, as the same burner family can use different servomotor variants.
• Check the part number on the existing servomotor and compare it with 3013395.
• Inspect the mounting points, drive coupling and electrical connector on the existing unit for damage before fitting a replacement.
• Check the linkage and damper for mechanical binding, as a seized linkage can mimic a failed servomotor.
