B1370155 – HIGH TEMPERATURE LIMIT SWITCH (DISC, DEEP BACK, L120°)

High-temperature limit switch for Goodman/Amana equipment, recorded as a disc-type switch with a deep back and an L120 degree F opening point. It breaks the control circuit when its sensing disc reaches the set temperature, protecting the cabinet and heat exchanger from over-temperature operation. The deep-back body style determines how the switch sits in its mounting opening, so confirm the physical profile as well as the temperature rating. Goodman’s own name for this part is AUXILIARY LIMIT SWITCH 120F — it is the blower-compartment auxiliary limit (L120-30F, auto reset), not a flame rollout switch and not the primary high limit. Some listings elsewhere mislabel it as a rollout. Make sure you are replacing the right switch. Published application data. Always match the full model and serial number on your unit before ordering.
