The Goodman 10123538 Manual Reset Limit Switch is a genuine OEM safety control for the Goodman ACEC960603BNAA gas furnace. This normally-closed thermal switch opens to shut off the gas valve if it senses an over-temperature or flame-rollout condition, and requires a manual reset before the furnace can restart — a deliberate safety design that prevents the unit from re-firing into a fault. If your furnace locks out and will not relight, a tripped or failed manual reset limit is a leading cause.

Specifications

OEM Part Number: 10123538
Part Type: Manual Reset Limit / Rollout Safety Switch
Function: Normally closed; opens on over-temperature, manual reset
Brand: Goodman (also fits select Amana builds)
Fits Model: ACEC960603BNAA
Fit: Direct OEM replacement — factory trip point and bracket

OEM vs. Generic

Limit switches are calibrated to a specific trip temperature. A generic switch with the wrong setpoint can nuisance-trip or, worse, fail to protect the heat exchanger. The genuine Goodman 10123538 carries the factory-specified open temperature and mounting footprint for the ACEC960603BNAA, so it protects exactly as designed. For a safety control, always choose OEM.

Installation Difficulty

Moderate (3/5). Requires removing two mounting screws and transferring the spade wire connectors. Shut off all power and gas before servicing. If the switch trips again after reset, do not bypass it — have the root cause (blocked vent, dirty filter, failing blower) diagnosed by a qualified technician.

Genuine OEM safety part. Confirm your full model and serial before ordering.
