Blower running continuously is a common furnace issue that wastes energy and impacts comfort. However, identifying the root cause can help you resolve it quickly. At Steve Patrick Air, we specialize in diagnosing and repairing blower problems to keep your system running efficiently.
Check the Thermostat Fan Setting
The first step is to inspect the thermostat’s fan setting. If it’s set to “On,” the blower will run constantly. Switch it to “Auto” so the blower only runs during heating cycles.
Tip: If adjusting the fan setting doesn’t help, your system may need professional inspection.
Inspect the Limit Switch
A malfunctioning limit switch often causes the blower to run continuously. The limit switch regulates when the blower starts and stops. A stuck or damaged switch can prevent it from shutting off.
Quick Fix: Reset the limit switch if possible, or call a professional to replace it.
Check for Wiring Issues
Loose or damaged wiring can cause the blower to stay on even when the furnace is not heating. Furthermore, electrical faults in the control board may disrupt normal operation.
What to Do: Inspect visible wiring for damage, but leave complex electrical repairs to a professional for safety reasons.
Test the Relay Switch
The relay switch sends power to the blower motor. A faulty relay switch may continue sending power even when the furnace is off. Additionally, this can lead to unnecessary wear on the blower motor.
Solution: Replace the relay switch if it is defective.
Common Causes of a Blower Running Continuously
- Thermostat Fan Setting: Set to “On” instead of “Auto.”
- Faulty Limit Switch: Prevents the blower from turning off.
- Wiring Problems: Loose or damaged wiring disrupts control signals.
- Defective Relay Switch: Continues sending power to the blower motor.
