62-24164-03 – SPARK IGNITOR (5/16″ QUICK CONNECT, RHEEM)
Spark ignitors arc to ignite the burner — cracked porcelain, a rounded-off electrode tip, or carbon buildup means it's done. Snap a phone pic of your existing connector before driving over, or just bring the old one in and we'll match it at the counter.

Symptoms of failure
- Furnace clicks and the inducer runs but the burners never light
- Ignitor glows dim orange instead of bright white
- Ignitor does not glow at all
- Furnace tries three times then locks out
- Visible crack or chip in the ignitor element
- Intermittent - lights fine some mornings, not others
Seeing these does not always mean this part is the culprit. Bring the old one in and we will meter it at the counter, free, before you buy.
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.

Installing it yourself
- Power off at the furnace switch and confirm 0V. Let the ignitor cool - it runs well over 1,800F.
- Never touch the element with bare fingers. Skin oil creates a hot spot and shortens its life.
- Photograph the bracket position and the plug routing.
- Remove the mounting screw and unplug the connector.
- Match the VOLTAGE, not just the shape. 80V, 95V and 120V ignitors look similar and are not interchangeable.
- Fit the new ignitor at the same depth and angle in the burner flame path.
- Restore power and watch a full cycle before you close the door.
- Bring the old one in - we will confirm the voltage family before you buy.
Power off at the disconnect first, every time. Not sure partway through? Bring it to the counter and we will walk it with you.
Fits these models
- Rheem Classic Series gas furnaces (RGRA, RGFD, RGLE families)
- Ruud Achiever Series gas furnaces (UGRA, UGFD, UGLE families)
- Most Rheem / Ruud gas furnaces using the 62-24164 ignitor family
- Verify connector style (round pin vs 5/16" quick-connect) before swapping
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.
