Goodman 0130F00038 Auxiliary Limit Switch (Light Blue)

The genuine OEM Goodman 0130F00038 auxiliary limit switch is a direct replacement for the DMP125-52AA gas furnace. This color-coded (light blue) thermal safety switch protects the furnace from overheating by interrupting power to the gas valve and control circuit if temperatures exceed its factory-set trip point. It is a normally-closed, temperature-activated cutout that automatically resets once the assembly cools.

Specifications

OEM Part Number: 0130F00038
Compatible Model: DMP125-52AA
Type: Auxiliary (rollout/high) limit switch, snap-disc
Color code: Light blue
Action: Normally-closed, auto-reset thermal cutout
Function: Overheat / secondary limit protection
Brand: Goodman / Amana

OEM vs. Generic

Because a limit switch is a safety device, the trip temperature matters. The genuine OEM 0130F00038 is calibrated to the exact set point the furnace was engineered for. Generic snap-disc switches may look identical but carry different trip temperatures — installing the wrong rating can either nuisance-trip or, worse, fail to protect the heat exchanger. Always match the OEM color code and part number.

Installation Difficulty

Easy (1/5). Usually two mounting screws and two push-on spade terminals. Shut off power and gas before servicing, and confirm the replacement carries the same light-blue calibration. Repeated tripping after replacement points to an airflow problem (dirty filter, blocked coil, or failing blower) that should be corrected.

Covered by our DMP125-52AA fitment guarantee. Contact info@nationalhvacparts.com with compatibility questions.
