Goodman 10123518 Manual Reset Limit Switch

The genuine Goodman/Amana 10123518 manual reset limit switch is a high-temperature safety control for the AMV90453BXBB gas furnace. This normally-closed thermal switch opens to shut off the burners if the furnace overheats, then requires a manual reset button press to restore operation — a deliberate design that flags an underlying airflow or venting fault instead of silently cycling.

OEM Part Number: 10123518
Type: Manual reset high-limit switch
Function: Normally closed, opens on over-temperature
Reset: Manual push-button
Compatible Model: AMV90453BXBB

OEM vs. Generic

OEM switches are calibrated to the exact trip temperature specified for this furnace's heat exchanger. Generic limit switches with mismatched setpoints can cause nuisance tripping or, worse, fail to trip when needed. Choose OEM for correct calibration and reliable safety performance.

Installation Difficulty

Easy to Moderate. Two mounting screws and two spade terminals. Always cut power at the disconnect first. If the switch has tripped repeatedly, diagnose the root cause (dirty filter, blocked vent, failing blower) before replacing.
