The Goodman 10123529 is a genuine OEM manual-reset high-limit switch built for the ACES800603AXAA gas furnace and compatible Goodman/Amana models. This safety control opens the burner circuit if the heat exchanger overheats — for example from a blocked filter, failed blower, or restricted ductwork — and requires a manual press to reset, ensuring the underlying fault is addressed before the furnace re-fires. If your furnace locks out on overheat or won't restart after a high-temperature trip, this switch is a common culprit.

Specifications

Type: Manual reset, normally-closed high-limit
Function: Burner cutoff on over-temperature
Mounting: OEM bracket / direct-fit
Fits: ACES800603AXAA and related Goodman/Amana furnaces
OEM Part #: 10123529

OEM vs. Generic

The genuine OEM switch is factory-calibrated to the exact trip temperature specified for this furnace. Generic limit switches with the wrong setpoint can nuisance-trip or, worse, fail to protect the heat exchanger. Because this is a safety device, OEM is strongly recommended.

Installation Difficulty

Easy (2/5). Cut power at the breaker, disconnect the two spade terminals, unscrew the mounting plate, and install the replacement in the same orientation. Typically a 15–20 minute job. Reset the switch and confirm normal heating operation.
