• 40100-02-BK PRIMARY CONTROL &

Bard part number 9022-036 is an OEM primary control used on Bard oil-fired heating equipment to manage safe burner operation by coordinating the ignition sequence and monitoring flame to prevent unsafe firing conditions. A failed or intermittent primary control can cause no-heat calls, nuisance lockouts, or improper burner cycling, so replacing it with the correct Bard-specified control is the best way to restore reliable starts and proper safety timing. Because primary controls can be wired and configured differently across furnace models and revisions, confirm your furnace model and the existing control number on the unit (your note references 40100-02-BK) before ordering to ensure correct compatibility and wiring match.
