According to Heil N96MSN manufacturer product information:
Performance 96 Gas Furnace
N96MSN checks the pressure-switch state before ignition
The N96MSN sequence starts with a control self-check and pressure-switch contacts before the inducer starts. Describe the observed sequence from outside the cabinet: whether the furnace attempts to start, lights, or loses flame. Internal pressure-switch and electrical checks belong to the contractor.
According to Tempstar-linked N96MSN installation, start-up, operating and service instructions, N96MSN-03SI:
The furnace control performs a self-check, verifies the pressure switch contacts LPS and HPS are open, and starts the inducer motor IDM.
Keep flame proving distinct from a blower complaint
The same manual describes a separate failure to prove flame after the gas valve opens. Preserve whether flame never establishes or disappears during the attempt, rather than treating every no-heat complaint as a blower replacement. Ask the contractor to identify the matching ignition and sensing checks.
The Tempstar-linked N96MSN installation, start-up, operating and service instructions, N96MSN-03SI also explains:
If the burner flame is not proved within two seconds, the control CPU will close the gas valve GV, and the control CPU will repeat the ignition sequence for up to three more Trials-For-Ignition before going to Ignition-Lockout.
