Rheem Furnace Ignitor Replacement: 801T Spark
If you smell gas or a CO alarm sounds, leave the home and call the gas utility or 911 from outside.
For Rheem 801T ignition service, contact an independent heating contractor and identify the direct-spark system before requesting an ignitor. The covered manual specifies direct spark and separate failed-ignition diagnostics. A hot-surface replacement description from another furnace does not establish the right component for this control family.

801T direct spark changes the replacement question
This service intent uses the common ignitor wording, but the documented component is part of a direct-spark system. Give the contractor the failed-ignition display and complete model. Ask for the diagnosed electrode, wiring or control concern rather than ordering a glowing hot-surface element by default.
