Replacing the SP4L-151-1 Blower in a Montage pellet stove:

The blower is located on the left side of the unit behind the control board side panel. The blower can be removed from the side, through the service panel or from the rear by removing the rear access panel. As always, when performing work on any stove, always unplug the unit from the power supply.

• Locate the motor and find the four screws or nuts that secure the motor
• Remove the screws or nuts
• Unplug the blower from the wiring harness
• Install new Blower to mounting post and tighten screws or nuts
• Reconnect power

If your blower is buzzing or vibrating when it's on, remove it and look inside at the blower wheel, you may have something foreign caught in the blower wheel, such as a pellet. Hair and other debris should be removed from the blower wheel at least once a year. Symptoms of a poorly performing blower will be excessive noise, vibration or heat. If the blower is clean and you are still experiencing problems, replace the blower. In rare instances, the control board may be sending a modified waveform to the blower. If you replace the blower and the vibrations or excessive heat are still present, replace your controller.

Current versions of the SP4L-151-1 blower are a sealed bearing that requires no lubrication, though from time to time we do see parts come in from the manufacturer that are made to the original spec that requires lubrication. This will be indicated on the listing table attached to the blower.
