62-24164-03 – SPARK IGNITOR (5/16″ QUICK CONNECT, RHEEM)

If your Rheem furnace uses spark ignition (not a hot surface ignitor) and won’t light, this OEM spark ignitor is the replacement. It has a 5/16″ quick connect terminal — make sure yours matches before buying. Rheem also makes a version with a round pin (62-24164-01).

Replaces: 62-24164-03

Fits: Rheem and Ruud furnaces with spark ignition systems using 5/16″ quick connect.

How do I know if my spark ignitor is bad?

Furnace tries to fire but no audible spark or visible arc at the burner. Pull the ignitor — cracked porcelain or a rounded-off electrode tip means replace.

Are connector styles interchangeable?

No. Round pin and 5/16" quick-connect are NOT interchangeable on the same OEM family. Verify your existing connector before ordering — or bring the old part in.

How long do spark ignitors last?

5-10 heating seasons typical. Hard-water condensate, corroded burners, or a control board firing too many cycles per call all shorten life.
