Honeywell Ignition control QM100A1009

The Honeywell QM100A1009 is an ignition control box for burners. It supports gas or oil fuel and flame detection via an ionisation electrode or UV/IR scanner. The control reads pressure switches and the flame detector as monitored inputs. Its safety feature is lockout on failure. This control is not interchangeable across series.

Replacement controls of this type are selected by matching the exact series and type designation, supply voltage, safety and pre-purge times, and the flame detection method (ionisation, UV, or IR). The base or plug pattern must also correspond to the existing wiring. Controls of this nature are normally not interchangeable across series, even within the same brand; a mismatched safety time creates a safety hazard, not just a functional inconvenience. Before ordering, verify the appliance’s existing control part number and the required safety times.
