Goodman 20269903 Auxiliary Auto Reset Limit Switch

The 20269903 is a genuine OEM auxiliary auto-reset limit switch for the Goodman GMPE100-4 gas furnace and compatible Goodman/Amana models. Serving as a secondary safety, it monitors temperature at the blower compartment or auxiliary location and interrupts the control circuit if the furnace overheats. Its automatic reset design restores the circuit once temperatures return to normal, allowing the furnace to resume operation after a transient over-temperature event without a manual trip.

Specifications

OEM Part Number: 20269903
Type: Auxiliary auto-reset limit switch
Function: Secondary over-temperature protection
Reset: Automatic (self-restoring)
Terminals: Spade connectors
Fits: Goodman GMPE100-4 and compatible furnaces

OEM vs. Generic

This genuine Goodman switch is calibrated to the correct auxiliary trip and reset temperatures and matches the original mounting. Generic auto-reset limits can chatter or short-cycle if the setpoint is off. Because it protects against overheating, we recommend the OEM part for dependable operation.

Installation Difficulty

Moderate (3/5). The switch installs with two screws and two spade connectors in about 15 minutes. Cut gas and power before service. If it trips repeatedly, diagnose airflow and blower issues rather than relying on the auto-reset feature.
