Ao Smith 100113158 Spark Module

Product Description

The AO SMITH 100113158 is a spark module designed to initiate ignition in water heating systems. The module generates the high-voltage pulse needed to ignite the burner, providing reliable spark sequencing during each call for heat. It serves as a direct replacement component for units where the original ignition module has failed or become unreliable. Licensed plumbers and water heater service technicians are the primary installers of this type of control component.

This spark module is intended for use in residential and light-commercial water heating applications where AO SMITH equipment is installed. It is suited for service calls where ignition failure, nuisance lockouts, or no-light conditions have been diagnosed and traced to the ignition module itself rather than the gas valve or pilot assembly.

Key Features

• Replacement spark module for restoring proper ignition function
• Designed to match OEM ignition sequencing behavior

• Direct replacement part for simplified serviceability

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater service technician. Before servicing, shut off the gas supply and disconnect electrical power to the water heater. Handle all ignition wiring connections carefully and confirm all leads are fully seated before restoring power. Follow applicable local codes and the manufacturer service documentation throughout the procedure.
