Goodman B1370145 Flame Rollout Switch (300°F)

The B1370145 is a genuine Goodman/Amana 300°F manual-reset flame rollout limit switch for the AMV80704BXA gas furnace. Mounted on the burner bracket, this critical safety control opens the gas-valve circuit the instant it senses a flame rollout — flames escaping the heat-exchanger inlet caused by a blocked flue, cracked exchanger, or restricted combustion air. When it trips, it locks out and requires a manual reset, alerting the technician to a serious underlying condition that must be diagnosed before restarting.

Specifications

OEM Part Number: B1370145
Trip Temperature: 300°F
Type: Flame rollout limit, snap-disc
Reset: Manual (push-button)
Contacts: Normally closed (opens on rollout)
Fits: AMV80704BXA and compatible Goodman/Amana furnaces

OEM vs. Generic

The OEM B1370145 trips at the precise 300°F factory setpoint with correct bracket and terminal fit. A generic rollout switch with the wrong temperature rating can defeat a life-safety function — either failing to protect against combustion spillage or nuisance-tripping. For rollout protection, use only the specified OEM part.

Installation Difficulty

Easy — cut power, transfer the two wire leads, unscrew the switch from the burner bracket, and mount the replacement. Under 15 minutes. Always diagnose why the original tripped before returning the unit to service.
