Restore safe operation to your Goodman/Amana AMVC81005CNCA two-stage variable-speed furnace with this genuine OEM 0130F00508 air pressure switch. This diaphragm-actuated safety control proves adequate combustion-air and vent draft before allowing the ignition sequence to proceed. A failed pressure switch is one of the most common causes of a furnace that ignites briefly then shuts down, or that locks out on repeated failed light attempts.
This is a genuine OEM switch calibrated to the exact trip point specified for your furnace's inducer and heat exchanger design. Aftermarket switches with the wrong actuation setpoint can cause nuisance lockouts or, worse, allow operation under weak-draft conditions. We recommend OEM for any safety-related control.
Replacement takes about 15–20 minutes for a competent DIYer: cut power at the disconnect, photograph the wiring, transfer the two spade terminals and the silicone hose, and mount to the existing bracket. Always verify draft operation with a manometer after service. If you are not comfortable working around the combustion assembly, use a licensed HVAC technician.
