The Goodman B1370819 Blower Door Safety Switch is a genuine OEM interlock switch used on the ADV80703BXA gas furnace and compatible Goodman/Amana models. This normally-open door switch cuts power to the blower and control circuit whenever the blower access panel is removed, preventing the furnace from operating with the door off. A worn or stuck door switch is a common cause of a furnace that won't start, cycles unexpectedly, or trips only when the panel is secured.

Specifications

  • Part type: Blower-door safety interlock switch
  • OEM part number: B1370819
  • Fits: Goodman ADV80703BXA furnace
  • Function: Normally-open plunger interlock, de-energizes blower/control circuit when door is open
  • Mount: Direct OEM replacement — no bracket modification required

OEM vs. Generic

Our OEM Goodman switch is engineered to the exact plunger travel, contact rating, and mounting footprint of the original, ensuring the door closes fully and the interlock seats correctly. Generic universal switches may fit physically but can require plunger adjustment and may not match the original contact rating — we recommend OEM for a reliable safety circuit.

Installation Difficulty

Easy (1 of 5) — 10–15 minutes with a nut driver. Disconnect furnace power, remove the blower door, unplug the two spade terminals, unclip the old switch, snap in the new B1370819, reconnect, and reinstall the panel. Always verify power is off at the breaker before servicing.

What symptoms mean I need a new door switch?
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?

To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman door switch?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
