Genuine Goodman 0130F00038 Auxiliary Limit Switch

The 0130F00038 is a factory-original auxiliary (high-limit / rollout) safety switch engineered for the Goodman & Amana AMS81005CXAB 80% AFUE multi-speed gas furnace and related models sharing this heat-exchanger assembly. This is the light-blue color-coded variant — the color denotes its calibrated trip temperature, so matching the original color is critical for correct, safe operation. When the switch senses an over-temperature or flame-rollout condition, it opens the circuit and shuts the burners down, protecting the heat exchanger and your home.

Specifications

OEM Part Number: 0130F00038
Type: Auxiliary / high-limit safety switch (SPST, opens on rise)
Color code: Light Blue (calibrated trip temperature)
Fits: Goodman / Amana AMS81005CXAB and compatible 80% furnaces
Function: Flame-rollout & over-temperature protection
Material: Bimetal disc with high-temp phenolic housing

OEM vs. Generic

Because this is a safety component, we strongly recommend the OEM 0130F00038. Generic bimetal switches often carry the wrong trip point or mounting geometry, which can cause nuisance lockouts — or, worse, fail to trip when needed. The genuine part guarantees the exact calibration Goodman engineered for this cabinet.

Installation Difficulty

Easy (2/5). Two-screw mount with quarter-inch spade terminals; a competent DIYer can swap it in 10–15 minutes. Always disconnect power at the furnace switch/breaker before servicing. If you are unsure why the original tripped, have an HVAC technician diagnose the root cause before replacing.
