Amana-Goodman 10250815 Limit Switch

The Amana-Goodman 10250815 Limit Switch is a critical safety component engineered for precise thermal regulation within residential HVAC systems. This OEM Goodman furnace part operates on an auto-reset mechanism, featuring a calibrated 75-125F temperature range designed to monitor internal heat exchanger conditions. When supply air temperatures exceed the safe 125°F threshold, the circuit opens to deactivate the burner, preventing localized overheating and potential equipment damage. Once the system cools to 75°F, the switch automatically closes to resume standard heating cycles. Constructed for durability in high-cycle environments, this 75-125F auto limit switch ensures consistent furnace high limit protection across various Goodman and Amana gas furnace models. For technicians troubleshooting furnace short cycling or open-limit error codes, verifying the continuity of this limit switch replacement is a standard diagnostic step. Its compact footprint allows for seamless integration into the existing wiring harness, maintaining the HVAC safety control integrity required for professional code compliance.

• Precise Thermal Calibration: Reliable 75°F to 125°F range prevents heat exchanger stress.
• Automated Reset Functionality: Eliminates the need for manual intervention after a temporary temperature spike.
• OEM Compatibility: Genuine Amana-Goodman replacement part ensures exact fit and electrical matching.
• Enhanced Safety: Primary defense against furnace overheating and airflow-related malfunctions.

• How do I test the Goodman 10250815 limit switch? Use a digital multimeter to check for continuity across the terminals when the furnace is cool. If the switch shows no continuity (open circuit) at room temperature, it has failed and requires replacement.
• What causes this limit switch to trip repeatedly? Frequent tripping is often caused by restricted airflow, such as a clogged air filter, blocked return vents, or a failing blower motor assembly.
• Can I bypass this switch for testing? While jumping the switch can confirm a diagnostic theory, never leave a furnace running without a functional limit switch, as it poses a significant fire hazard.
