First check

1 Airflow before you touch the limit

On Amana AM9S96 a limit is airflow or overfire until proven otherwise. Do not replace the limit first. Filter, blower wheel, A-coil, and the heat-speed setting for THIS motor (tap, model plug, or communicating CFM — not a sister SKU chart). Filter, coil, return, heat-speed tap. A 96% coil on a low heat tap will limit.

Expect: Heat tap / rise: Match the installer’s tap to the rise range on the rating plate (typically 35–65°F).

The rest of the walkthrough is Diagnose.

On the plates

  • Filter, coil, return, heat-speed tap. A 96% coil on a low heat tap will limit.
  • Rise vs rating plate.
  • Clock the meter — overfire trips limits with a clean filter.
