Common Issues With Combustion Blowers
You might notice several problems with your Harman pellet stove’s combustion blower. Understanding these issues can help identify the reasons for the blower’s continuous operation.
Symptoms Of A Running Combustion Blower
Several symptoms indicate your combustion blower runs constantly.
- Constantly Spinning Motor: The blowers should typically stop once the firebox reaches a certain temperature. If it continues, that indicates an issue.
- Excessive Noise: A running blower makes a noticeable sound. If the noise level is higher than normal, something may be off.
- Increased Power Consumption: A blower that doesn’t stop causes higher electricity bills. Monitor your energy usage for unexpected spikes.
- Temperature Fluctuations: If your space doesn’t maintain a consistent temperature, it might be due to the blower’s malfunction.
Possible Causes Behind The Issue
Understanding the potential causes can facilitate quick troubleshooting.
- Faulty Limit Switch: If the limit switch is defective, it fails to send a signal to stop the blower. Inspect this component first.
- Blocked Vent System: Accumulated debris in the vent can restrict airflow, causing the blower to work harder and run continuously. Ensure vents are clean and clear.
- Incorrect Settings: Sometimes, the settings on your thermostat or stove may cause the blower to operate longer. Check user settings for any anomalies.
- Blower Motor Malfunction: The motor itself might experience technical difficulties. If the motor is jammed or damaged, it won’t shut down.
- Wiring Issues: Broken or exposed wires can disrupt the blower’s operational signals. Examining wiring connections can often reveal hidden problems.
By identifying these symptoms and potential causes, you’re on track to troubleshoot the issue effectively. Regular maintenance plays a crucial role in ensuring the longevity of your stove’s components.
Troubleshooting Steps
Follow these troubleshooting steps to identify and resolve the issue of your Harman pellet stove’s combustion blower running continuously.
Checking The Thermostat Settings
Verify your thermostat settings first. Make sure it’s set to a temperature above the current room temperature. If the thermostat is set too low, it can lead to the blower running continuously. Adjust the settings and wait a few minutes to see if the blower stops. If it continues running, check for any programming issues or faulty wiring connecting the thermostat to the stove.
Inspecting The Flame Sensor
Inspect the flame sensor next. A dirty or malfunctioning flame sensor may cause the combustion blower to run nonstop. Clean the sensor with a soft cloth to remove any soot or buildup. If cleaning doesn’t resolve the issue, consider replacing the flame sensor. Ensure the sensor is properly connected to the control board as loose connections can also trigger the blower to run.
Examining The Control Board
Examine the control board carefully. A fault in the control board can lead to the blower running continuously. Look for any visible signs of damage such as burnt components or loose wires. If everything appears intact but the issue persists, a malfunction in the control board could be the cause. Consult your manual for troubleshooting specific to your model or contact a professional technician for assistance.
When To Seek Professional Help
You face persistent issues with your Harman pellet stove, especially if the combustion blower won’t stop running. In certain situations, seeking professional assistance becomes essential.

If you notice frayed or damaged wiring, a professional inspection is crucial. Wiring issues can pose fire hazards and may require specialized tools for safe repairs. - Complex Control Board Issues
If the control board shows signs of malfunction, such as unresponsive buttons or erratic behavior, enlist a professional. Control board replacements often necessitate advanced expertise. - Unusual Noises or Vibrations
If your stove emits strange noises or vibrations, professional help can determine the underlying cause. These symptoms could indicate serious mechanical failures. - Lack of Familiarity with Repairs
If you’re unsure about diagnosing or fixing issues, it’s safer to consult with a technician. Attempting repairs without adequate knowledge might worsen the situation. - Guaranteed Safety and Performance
