Goodman 0130F00038 Auxiliary Limit Switch (Light Blue)

The Goodman 0130F00038 auxiliary limit switch is a genuine OEM secondary high-temperature safety control for your AMSS921004CNAA furnace. Identified by its light blue cap for correct field placement, this auxiliary limit is typically mounted near the blower deck or heat exchanger to interrupt the control circuit if temperatures exceed a safe threshold in that zone — backing up the primary limit and protecting components from heat damage caused by restricted airflow or a failed blower.

Specifications

OEM Part Number: 0130F00038
Type: Auxiliary / secondary limit switch (normally closed)
Identifier: Light blue cap
Brand: Goodman / Amana
Application: Furnace blower / heat exchanger area
Compatible Model: AMSS921004CNAA

OEM vs. Generic

The color-coded cap on this genuine Goodman OEM switch matches the factory trip rating for its mounting location — critical, since auxiliary limits are position-specific. Generic substitutes often lack the correct color/rating, risking nuisance trips or missed protection. Match OEM color to OEM color for safe operation.

Installation Difficulty

Easy (1/5). Two screws and two spade terminals, roughly a 10-minute swap. Kill power at the furnace disconnect and breaker before starting, and confirm the replacement cap color matches the part you removed.

Fits Goodman and Amana furnaces including AMSS921004CNAA. Need fitment help? info@nationalhvacparts.com.
