When your RV range burner stops sparking, the ignitor electrode is almost always the culprit. This OEM-spec replacement electrode from Suburban restores reliable ignition to your cooktop or range without guesswork -- it is engineered specifically for Suburban SR3S (short oven), SR3L (long oven), and SC3 (slide-in cooktop) models and drops in with no modifications required.
The ignitor electrode is the small ceramic-mounted probe positioned beside each burner that generates the spark to light the gas. Over time, grease buildup, physical damage, or simple wear causes the electrode tip to fail or crack its ceramic insulator, resulting in weak, intermittent, or no spark. Replacing the electrode is a straightforward DIY repair that typically takes under 30 minutes with basic hand tools.
Suburban part number 525034 is also sold and referenced as NBK Parts 20280 -- both refer to the identical component. If you searched by either number, you are in the right place.
Engineered specifically for Suburban SR3S, SR3L, and SC3 ranges. No drilling, adapting, or bracket modification needed.
Electrode body is 1-3/8" long x 3/16" diameter -- matches the original footprint exactly for clean installation.
11/16" x 3/8" bracket keeps the electrode positioned at the correct gap distance from the burner head for consistent spark.
Listed as both Suburban 525034 and NBK 20280 -- confirmed same component, no substitution risk.
Ignitor electrodes on RV ranges take constant abuse from heat cycling, grease splatters, and vibration during travel. The ceramic insulator is particularly vulnerable -- a hairline crack allows spark energy to ground out before it ever jumps to the burner, causing a clicking igniter module to produce no visible spark at the burner. Inspect your electrode for:
Before ordering, confirm your range model by checking the data plate inside the oven compartment or on the back of the cooktop frame. The SR3S (short oven), SR3L (long oven), and SC3 (slide-in cooktop) are all served by this same electrode part number.
