The Linear 2500-552 is an OEM replacement run capacitor designed for use in Linear and OSCO gate operator systems. Rated at 370 VAC. Capacitor with sealed housing, film or electrolytic dielectric construction. This part is manufactured by Nortek/Linear LLC/Linear PRO Access and is available through authorized distributors.
A: The 2500-552 is rated 20 MFD (microfarad) and 370 VAC, which are the standard run capacitor values for the Linear SWR and SLR gate operator motors.
A: A run capacitor improves motor efficiency and starting torque by maintaining a phase shift in the motor windings during normal operation, unlike a start capacitor which only assists during startup.
A: Symptoms of a failed run capacitor include slow gate movement, motor humming without rotation, overheating, or the operator failing to start under load.
A: The 2500-552 is confirmed compatible with Linear SWR and SLR models. Check your operator's parts manual to confirm the 20 MFD / 370 VAC specification before ordering for other models.
A: Run capacitors should be replaced as like-for-like: same MFD value (+/- 5%) and equal or greater voltage rating. Using an incorrect value can damage the motor or reduce operator performance.
