Blower Motor Fault Diagnosis
Diagnosing a blower motor fault, indicated by error code 113 on your Lennox Heat Pump SL22KLV, requires a systematic approach.
You’ll need to check the blower motor’s electrical connections, ensuring proper wiring and verifying that the motor is receiving the correct voltage. Measure the blower motor’s amp draw to determine if it’s within the specified range; if not, it may indicate a faulty motor or a problem with the control board.
Visually inspect the blower motor and its components for physical damage, wear, or corrosion that may be contributing to the fault. If you’re not comfortable with these steps, it’s recommended to consult a professional HVAC technician for accurate diagnosis and repair.
Causes of Blower Motor Failure
You’ll find that high voltage spikes and voltage fluctuations can peak, causing the motor to fail prematurely.
Installation errors are also suspected to contribute to blower motor failure, which can ultimately trigger error code 113.
High Voltage Spikes
High voltage spikes can be a silent killer of your Lennox heat pump’s blower motor.
When high voltage spikes occur, they can cause irreparable damage to your blower motor, leading to a Blower Motor Fault and error message 113.
Here are some ways high voltage spikes can affect your Lennox Heat Pump:
- High voltage spikes can cause motor winding failure, leading to a complete breakdown of your blower motor.
- Voltage spikes can also cause motor bearings to fail, resulting in increased noise and vibration.
- High line voltage can lead to overheating, reducing the lifespan of your blower motor.
- Voltage spikes can trigger false readings, causing your Lennox furnace to malfunction or shut down.
It’s essential to consult a professional HVAC technician to diagnose and repair high voltage spike issues to prevent further damage.
Voltage Fluctuations Peak
Voltage fluctuations peak, a significant contributor to blower motor failure, can occur when the power grid experiences high demand.
During peak hours, typically between 6-7 AM and 4-6 PM, voltage fluctuations can cause the blower motor to fail, resulting in the error code 113 being displayed on your Lennox Heat Pump Model SL22KLV.
Even a measured voltage of 125.4V, although within the permitted range, may still represent a peak load voltage that can contribute to blower motor failure if it frequently fluctuates.
To address this, take voltage readings every few hours to calculate the average voltage and notify your utility provider of any readings above 125V to prevent further blower motor faults.
Installation Errors Suspected
Improper installation of your Lennox Heat Pump Model SL22KLV is a suspected cause of the blower motor failure, leading to the error code 113.
This error message is a clear indication that something went wrong during the installation process in your home.
To avoid this blower motor fault, you should guarantee that the installation is handled by a professional with proper license verification.
- Hire a licensed expert: Certify the installer has a valid license to handle heat pump installations.
- Verify the installation: Double-check the installation manual and certify the installation is done correctly.
- Reset the system: After installation, reset the system to certify it’s working correctly.
- Regular maintenance: Regular maintenance can help you identify potential issues before they become error code 113.

Troubleshooting Steps for Error Code 113
You’ll need to identify high voltage issues, which can damage your Lennox heat pump’s components.
You should also check for voltage fluctuations, as these can trigger the error code 113.
High Voltage Issues
When your Lennox heat pump model SL22KLV displays error code 113, high voltage is the prime suspect.
This error code indicates a high voltage issue, which can be triggered by voltage above 132V. To troubleshoot, you’ll need to take voltage readings every few hours to calculate the average voltage.
Here are the steps to resolve the high voltage issue:
- Take voltage readings every few hours to identify readings above 125V.
- Report the high voltage readings to the power company to request a voltage adjustment.
- Ask the power company to inspect the transformer for potential issues.
- Verify that the high line voltage is within the acceptable range to prevent furnace operation disruption.
Voltage Fluctuations
Voltage fluctuations are a key contributor to the high line voltage issue indicated by error code 113.
As you troubleshoot this issue, crucially, understand how voltage fluctuations impact your Lennox heat pump’s performance.
Peak load usage, typically during 6-7 AM and 4-6 PM, causes voltage to increase, and the utility provider adjusts power levels to counteract the decrease.
To resolve error code 113, take voltage readings every few hours to calculate the average voltage.
If readings exceed 125V, notify your utility provider, who may need to adjust power levels or inspect the transformer supplying your residence or street.
This will help resolve the high line voltage issue and potentially rectify the installation error.

Repair or Replacement Options
The Lennox heat pump error code 113 diagnosis is complete, and it’s time to weigh your options.
You’ve identified the blower motor fault, now it’s time to decide on the best course of action.
- Replace the blower: If the fault lies within the motor, replacing it with a new one from Lennox or a compatible replacement part can resolve the issue.
- Inspect and clean the furnace: Guarantee the furnace is free from blockages and clean the low pressure switch, flame sensor, and gas valve issues.
- Check the limit switch: Verify the limit switch is functioning correctly, as a faulty switch can prevent the blower motor from operating.
- Consult a professional: If you’re unsure about the above steps or if the issue persists, consider consulting a professional HVAC technician to diagnose and repair the Lennox heat pump.
