The Goodman 0130F00038 Auxiliary Limit Switch is a genuine OEM secondary safety control (identified by its light blue color code) for AMSS920603BNAA gas furnaces and compatible Goodman/Amana models. Mounted near the blower or secondary heat-exchanger area, this auxiliary limit adds a backup overheat cutoff that de-energizes the burners if temperatures exceed safe levels — a second line of defense beyond the primary high limit.

Specifications

Type: Auxiliary automatic-reset thermal limit switch
Color code: Light blue (denotes factory trip temperature/rating)
Function: Secondary overheat safety cutoff
Fits: Goodman AMSS920603BNAA and select Goodman/Amana furnaces
OEM Part Number: 0130F00038

OEM vs. Generic

Like the primary limit, this auxiliary switch is color-coded to a precise trip point. The OEM 0130F00038 ensures the correct rating, form factor, and mounting for your furnace. A mismatched generic can trip early or fail to protect the system. Because this is a safety-critical control, OEM replacement is strongly advised.

Installation Difficulty

Easy–Moderate (2/5) — unscrew the two mounting screws, transfer the spade wire connectors, and mount the new switch in the identical position. Basic hand tools only. Always disconnect electrical power and shut off the gas supply first. If you're not comfortable, hire a licensed HVAC technician.
