About the Marley 3900-2002-518

The 3900-2002-518 is a fan motor from Marley Engineered Products, rated for 208–230 volts at 1550 RPM. It spins the heater's fan to move air over the heating element and push warm air into the room.

Signs of a failing motor include humming without the fan turning, grinding or squealing, slow startup, or a heater that overheats and cycles off on its limit.

Check your heater's model number against the compatible-models list on this page before ordering.

Installation Tips

Turn off power at the breaker and let the heater cool. Before disconnecting the old motor, take a photo of its wiring and note where the fan blade sits on the shaft. Move the blade to the new motor at the same position, mount the motor, reconnect the wires, and check that the blade spins freely before restoring power.
