Goodman B1370819 Blower Door Safety Switch

The Goodman B1370819 is a factory OEM blower-compartment door interlock switch engineered for the DDS81155CXA gas furnace and compatible Goodman/Amana models. This normally-open safety switch cuts power to the blower and burner circuit whenever the blower access panel is removed, protecting the technician and preventing the furnace from operating with the door off. A failed or stuck door switch is one of the most common reasons a furnace will not start or shuts down intermittently.

Specifications

  • OEM Part Number: B1370819
  • Type: SPST plunger-style door interlock / safety cutoff switch
  • Function: Disables blower & ignition when access panel is open
  • Fits: Goodman DDS81155CXA and select Goodman/Amana furnaces
  • Direct factory replacement — no wiring modification required

OEM vs. Generic

The genuine OEM B1370819 uses the correct plunger throw, contact rating, and mounting geometry so the panel seats properly and the switch closes reliably. Aftermarket generics often have a shorter plunger or weaker spring that can cause nuisance no-heat calls. For a safety-critical interlock, we recommend the OEM part.

Installation Difficulty

Easy — Typical replacement takes 10–15 minutes with a nut driver and a wire connector. Disconnect furnace power at the breaker, remove the two wire leads, unclip the old switch, and snap the new one into the bracket. Basic DIY skill level.

Always shut off power before servicing. If you are unsure of your furnace model or wiring, consult a licensed HVAC technician.

Common symptoms: unusual noises, intermittent operation, complete failure, or visible damage. Visit our diagnostic hub for symptom-based troubleshooting.
Is this door switch compatible with Bryant or Payne too?
