Common Technical Questions

Is the RXD7206 compatible with all Laars Pennant and Mighty Therm models?
While the RXD7206 control module is a common part for several high-efficiency series, specific sub-models and furnace versions require specific firmware revisions. Always check your unit's data plate and wiring diagram to confirm HVAC part compatibility before replacing a boiler control board.

Does this module require professional calibration after installation?
This HVAC replacement part is factory-calibrated. However, technicians should perform a combustion analysis and verify flame signal strength (microamps) following installation to ensure the Laars heating system is operating at peak efficiency.

What are the symptoms of a failing Laars RXD7206?
Common indicators include intermittent ignition failure, erratic cycling, or "no heat" calls where the inducer motor runs but the gas valve fails to energize due to control module logic errors.
