The Bard 8554-019BX Flame Sensor .114 Rod is an OEM ignition safety component used in gas-fired heating sections of compatible Bard HVAC equipment to prove burner flame and keep the control board from locking out. When a sensor becomes worn, contaminated, or damaged, systems may short cycle or fail to stay lit, so replacing it with the correct Bard part helps restore reliable flame detection and proper heat operation. This boxed replacement is the current manufacturer part number that supersedes Bard 8554-019, and it is intended to match factory fit and electrical performance when installed per the unit service literature.
* Orders less than $50 may incure a minimum order fee.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
