Nuway Damper Motor A30072T

The Nuway A30072T is a damper motor supplied as a Siemens SQN30.111A2700 type unit, rated at 220V with a single relay. It drives the air damper on oil-fired boiler and burner assemblies, positioning the damper for pre-purge, firing and shutdown. It is listed for oil spares applications on Bentone equipment.

• The damper stays in one position and does not move through its full travel
• The motor hums or buzzes without driving the damper
• The burner locks out on start-up because the damper does not reach the purge or firing position
• Intermittent lockouts that clear on reset but return on the next cycle
• Visible damage, overheating or a burnt smell from the motor housing

• Confirm the existing motor's label matches SQN30.111A2700 and the A30072T part number
• Check the supply voltage at the appliance is 220V and the relay configuration matches the failed unit
• Verify the appliance and burner model against the manufacturer's parts list before ordering
• Inspect the damper linkage and shaft for mechanical binding, as this can mimic motor failure
