The genuine Goodman 0130F00038 Auxiliary Limit Switch is a factory OEM safety control engineered for the AMVM960805CXBA modulating variable-speed furnace and compatible Goodman/Amana gas furnace platforms. Identified by its light-blue housing, this normally-closed thermal limit opens the control circuit if it senses an over-temperature condition, protecting the heat exchanger and blower assembly from unsafe operation.
This is a genuine OEM Goodman component built to the exact temperature trip point and terminal configuration your furnace's control board expects. Generic aftermarket limit switches often use approximate trip temperatures that can cause nuisance lockouts or fail to protect the unit. For a safety-critical control like this, OEM is strongly recommended.
Easy to Moderate — a two-terminal swap for anyone comfortable working inside a furnace cabinet with power disconnected. Always shut off gas and electrical power before servicing. If you're unsure, we recommend a licensed HVAC technician.
Compatible with AMVM960805CXBA. Confirm your model and part number before ordering.
