Amana-Goodman 20028405 Pressure Switch
The Amana-Goodman 20028405 Pressure Switch is a critical safety component engineered for precision in high-efficiency Amana and Goodman furnaces. This 1.25" WC pressure switch serves as a diagnostic monitor, ensuring the inducer fan creates the necessary vacuum for safe combustion. Often referred to by its manufacturer part number 20028405 or the Tridelta series PPS10043-2335, this single-pole, single-throw (SPST) switch is a direct OEM replacement HVAC part. It effectively prevents the furnace from igniting if venting issues or restricted airflow are detected, protecting the heat exchanger and occupants. With its 1.25-inch water column sensitivity, it offers the exact calibration required for the closed-loop safety circuits found in modern gas heating systems. Integrating this robust furnace pressure sensor into your maintenance routine or repair ensures reliable system cycles and prevents "no-heat" calls during peak winter demand.
Key Benefits- Precise Safety Monitoring: Calibrated specifically to a 1.25" WC set point to ensure optimal venting and exhaust conditions.
- OEM Compatibility: Designed for a perfect fit in Goodman and Amana gas furnaces, eliminating the need for complex mounting modifications.
- System Protection: Automatically shuts down the heating cycle if pressure drops, preventing the buildup of dangerous combustion gases.
- High-Performance Construction: Built by industry leader Amana-Goodman to withstand the high-temperature environments of residential air handlers.
How do I know if my furnace pressure switch is bad?
If your furnace inducer motor runs but the igniter does not glow, or if you see a "pressure switch stuck open" error code on your control board, the 20028405 part may require replacement.
Is the Amana 20028405 compatible with other brands?
This part is specifically engineered for Amana, Goodman, and Janitrol units. Always verify the water column (WC) rating on your existing switch matches the 1.25" WC specification before installation.
Can I bypass a pressure switch temporarily?
No. Bypassing a furnace safety switch is dangerous and can lead to carbon monoxide leakage or equipment damage. Always replace a faulty switch with a certified OEM HVAC part.
