Whether you’re a seasoned technician or a homeowner, our goal is to help you understand and address common combustion blower problems with clarity and accuracy.
1. Understanding the Combustion Blower
The combustion blower is responsible for drawing in air for combustion and expelling exhaust gases, creating a steady and clean burn within the pellet stove. When it malfunctions, several problems may arise.
2. Common Symptoms of Combustion Blower Issues
Before troubleshooting, it’s essential to recognize the signs of combustion blower problems. These may include:
- Poor Ignition: Difficulty starting the stove or frequent shut-offs.
- Reduced Heat Output: The stove doesn’t produce enough heat.
- Excessive Smoke: Smoke escaping from the stove or unusual odor.
- Noisy Operation: Unusual sounds coming from the combustion blower.
3. Troubleshooting Steps
a. Check for Blockages: Inspect the blower and exhaust paths for any blockages, such as debris, soot, or foreign objects. Remove any obstructions that might impede airflow.
b. Inspect the Blower: Examine the combustion blower for visible damage, wear, or corrosion. Ensure it spins freely and without resistance. If it’s damaged, replace it.
c. Electrical Connections: Ensure that all electrical connections to the combustion blower are secure. Loose or damaged wires can disrupt the blower’s operation.
d. Blower Motor Test: Using a multimeter, test the combustion blower motor for continuity. If the motor fails this test, it needs replacement.
e. Pressure Switch Test: Some stoves have pressure switches that interact with the combustion blower. Test the pressure switch to ensure it’s functioning correctly. Replace if necessary.
f. Clean the Blower: Thoroughly clean the combustion blower and its housing, as accumulated dust and debris can hinder its performance. Ensure it’s free from obstructions that may obstruct airflow.
g. Consult the Manual: Refer to your pellet stove’s user manual for specific troubleshooting guidance, as procedures may vary by brand and model.
