The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for the WFM18090S5CXCC gas furnace and related Goodman/Amana units. This high-limit switch opens the control circuit when it senses excessive temperature — such as from a blocked flue, failed blower, or flame rollout — and shuts the furnace down to prevent damage or hazard. Because it is a manual reset device, it will not automatically re-close, forcing a technician to inspect the cause before the furnace can run again.

Specifications

Part Number: 10123529
Type: Manual reset high-limit / rollout switch
Function: Opens on temperature rise, requires manual reset button
Contacts: Normally closed (opens on fault)
Fits: WFM18090S5CXCC and compatible Goodman furnaces

OEM vs. Generic

Safety limits are calibrated to a specific trip temperature. This OEM 10123529 is set to Goodman's factory spec, so it protects at the correct threshold. Generic switches may trip early (nuisance shutdowns) or late (reduced protection). For a safety-critical part, OEM is strongly recommended.

Install Difficulty

Easy. Typically a two-wire, single-bracket swap. Shut off power and gas, note wire positions, unbolt the old switch, and mount the new one. About 15–20 minutes. If the switch keeps tripping after replacement, have a technician diagnose the underlying overheat condition.

Never bypass a manual reset limit switch — it is a required safety device.
