The Goodman B1370145 is a genuine OEM flame rollout limit switch rated to trip at 300°F, engineered for the AMS81155CXA gas furnace and compatible Goodman/Amana models. Mounted near the burner box, this manual-reset safety device opens the control circuit and shuts down the furnace if flames roll out of the combustion chamber—protecting the equipment and your home from overheating.

A tripped or failed rollout switch is a common cause of no-heat conditions. If the switch has opened repeatedly, replacing it with the correct OEM part restores safe operation, but the underlying cause (blocked flue, cracked heat exchanger, or dirty burners) should always be inspected.

  • Trip Temperature: 300°F
  • Reset Type: Manual
  • Function: Flame rollout safety limit
  • Fits: Goodman AMS81155CXA and compatible furnaces
  • OEM Part #: B1370145

OEM vs. Generic: The genuine Goodman switch is calibrated to the exact 300°F trip point and terminal spacing your furnace's wiring harness expects. Generic equivalents cost less and fit most applications, but trip tolerances and bracket geometry can vary. For a safety-critical limit, we strongly recommend OEM.

Install Difficulty: Easy (2/5). Disconnect power, unplug the two spade terminals, remove the mounting screws, and swap in the new switch. A basic nut driver is the only tool needed.

Frequently Asked Questions

Does this Limit Switch fit my Goodman AMS81155CXA — B1370145?

How do I replace the limit switch on my Goodman AMS81155CXA — B1370145?

What symptoms mean I need a new limit switch?
Common symptoms: unusual noises, intermittent operation, complete failure, or visible damage. Visit our diagnostic hub for symptom-based troubleshooting.
Is this limit switch compatible with Bryant or Payne too?
Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman limit switch?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
