Emerson 004817B Electronic Ignition Module

Product Description

The EMERSON 004817B is an electronic ignition module used in gas-fired heating and pool heating equipment. This component controls the ignition sequence that lights the main burner, replacing the function of a standing pilot with a more reliable, energy-efficient spark or hot-surface ignition cycle. It is a genuine OEM replacement part, supplied new in original factory packaging. Licensed HVAC technicians and pool equipment service professionals are the primary installers of this type of control component.

Electronic ignition modules of this type are found in residential and light commercial gas-fired systems, including pool heaters and spa heaters where intermittent pilot or direct spark ignition is specified. The 004817B is a factory-replacement part intended to restore proper ignition function when the original module has failed or become unreliable. Refer to the equipment manufacturer documentation to confirm fitment before installation.
