The Goodman B1370108 Flame Rollout Limit Switch is a genuine OEM safety control engineered for the Goodman GUPS120-5 gas furnace and compatible Goodman/Amana models. This manual-reset rollout switch monitors for burner flame rollout — a condition where the flame escapes the heat exchanger — and shuts down the furnace to prevent overheating, fire, and heat exchanger damage. A properly functioning rollout switch is essential for safe furnace operation.

Specifications

Trip temperature: 300°F
Reset type: Manual (push-button)
Configuration: Normally closed, opens on temperature rise
Terminals: 1/4" quick-connect spade
Function: Flame rollout / high-limit safety cutoff
Fits: Goodman GUPS120-5 and select Goodman/Amana gas furnaces

OEM vs. Generic

This is a genuine Goodman OEM part, calibrated to the exact 300°F trip point specified by the manufacturer. Generic aftermarket switches may trip at incorrect temperatures — nuisance-tripping or, worse, failing to trip during a real rollout event. For a safety-critical control, we recommend OEM to protect your equipment and household.

Installation Difficulty: Easy

Rated 1 of 5. Replacement typically takes under 10 minutes: disconnect power, unplug the two spade terminals, remove two mounting screws, and install the new switch in the same orientation. No refrigerant or gas-line work required. Always shut off electrical power and gas before servicing, and confirm the cause of any rollout condition before returning the furnace to service.
