Questions about this item

What temperature rating does the Goodman 10728343 limit switch use to open the circuit?

This safety control opens the burner circuit when the heat exchanger exceeds its calibrated trip point, then resets automatically once the temperature drops back into the normal operating range.

What mounting style and cabinet clearance does the 10728343 require inside the furnace?

The switch body fastens with two screws through its integral flange and slides into the existing bracket slot; allow enough depth for the probe to sit fully in the airstream without touching the heat-exchanger tubes.

Which step do installers most often miss when fitting the 10728343 limit switch?

After securing the switch, the wiring harness must be snapped onto the spade terminals in the correct polarity; reversing the leads prevents the control board from reading the limit state and leaves the furnace locked out.
