OEM Goodman Auxiliary Limit Switch (Light Blue) for AMVC8 — 0130F00038

The Goodman 0130F00038 Auxiliary Limit Switch (light-blue color-coded body) is a genuine OEM safety limit for the AMVC800804CNAB 80% AFUE two-stage gas furnace and compatible AMVC8/GMVC8 platforms. This auxiliary limit provides secondary overtemperature protection — typically mounted near the blower deck or burner box — and opens to shut down heating if abnormal temperatures are detected, backing up the primary limit control.

Specifications

• Part Type: Auxiliary limit switch (color code: light blue)
• Function: Secondary thermal overtemperature cut-out
• Fits: Goodman/Amana AMVC800804CNAB and related AMVC8 furnaces
• Reset: Automatic
• Type: OEM exact-fit replacement — factory trip temperature

OEM vs. Generic

Goodman color-codes auxiliary limits by trip temperature — the light-blue body indicates a specific factory cut-out point. Installing a generic or wrong-color limit risks the wrong trip temperature, which either nuisance-trips the furnace or defeats the safety it's meant to provide. This genuine OEM part guarantees the correct rating and bracket fit.

Install Difficulty: Easy

Roughly 10–15 minutes. Turn off power and gas, note the wire positions, remove the mounting screws, transfer the leads to the new switch, and reinstall. Confirm the color code matches the original before installing. If the limit keeps opening, correct the underlying airflow or venting problem rather than repeatedly replacing the switch.
