Goodman 10123529 Manual Reset Limit Switch

The 10123529 is a genuine Goodman manual-reset limit switch (rollout / high-limit safety) for the ACVM970603BNBA gas furnace. This normally-closed thermal switch opens the gas-valve circuit if it senses an over-temperature condition — typically caused by flame rollout, a blocked flue, or a failed blower. Because it is manual reset, it stays open after a trip and must be physically reset by pressing the button, alerting the homeowner that a safety event occurred rather than silently cycling.

Specifications

Part type: Manual-reset high-limit / rollout safety switch
OEM part number: 10123529
Action: Normally closed, opens on over-temperature
Reset: Manual push-button
Brand: Goodman (Amana/Janitrol compatible)
Compatible model: ACVM970603BNBA

OEM vs. Generic

This is a life-safety component — its calibrated trip temperature must match Goodman's engineering spec exactly. The OEM 10123529 carries the correct factory temperature rating and terminal layout. Generic switches with the wrong set-point can either nuisance-trip or, worse, fail to trip. Always use OEM for safety controls.

Installation Difficulty

Moderate (2/5). Shut off power and gas, photograph the wiring, swap the two spade terminals, and mount with the original screws — about 15–20 minutes. If it trips again after replacement, have a licensed technician diagnose the root cause before operating.
