Description
The Goodman 10123531SP is an OEM manual-reset high-limit switch designed to protect Goodman heating equipment from overtemperature conditions. Identified by its distinctive light purple color coding for easy field identification, this limit switch provides a critical layer of safety by shutting down the burner or heating element when temperatures exceed the set point — and requiring a deliberate manual reset before the system can resume operation.
Key Features
- Manual-reset design requires intentional operator action before resuming operation after a limit trip
- Light purple color coding for quick visual identification in multi-limit applications
- OEM Goodman replacement part — engineered to exact factory specifications
- Provides reliable overtemperature protection for furnaces and air handlers
- Direct drop-in replacement for compatible Goodman and Amana equipment
Application
This manual-reset limit switch is intended for use in Goodman and Amana brand furnaces and heating systems where the original 10123531SP limit switch requires replacement. The manual-reset feature is a safety-critical design: once the limit trips due to an overtemperature event, the system will not restart automatically, prompting the technician to diagnose and correct the root cause before restoring operation.
Why Manual Reset?
Unlike auto-reset limits that cycle the system back on once temperatures drop, a manual-reset limit demands hands-on intervention. This is especially important in situations where repeated cycling could indicate a blocked flue, restricted airflow, or other hazardous condition. The light purple color coding helps technicians quickly distinguish this component from other limit switches in multi-limit configurations.
