Trane 200A Contactor Rebuild Kit
Coil, armature, magnet and contact kit. Everything to rebuild a chattering 200A Trane chiller contactor in one teardown.
What's in the box
The core renewal parts, the same ones we sell individually, bundled at 21% off buying them separately.
New contacts, springs and hardware for all three poles, restoring the full current-carrying surfaces.
Fresh operating coil — the electromagnet that pulls the contactor in. A tired coil hums and runs hot.
The moving magnet face. Worn, pitted armature faces are the #1 cause of chatter — new contacts alone won't fix it.
The stationary magnet assembly. Mates with the new armature for a flat, quiet seal every time it closes.
Chattering contactor? This is the fix.
It's not just the contacts
That buzz and chatter comes from worn armature and magnet faces that can't seat flat anymore. Swap only the contacts and coil and the chatter comes right back.
Do it once, while you're in there
When you're already changing contacts and the coil, replacing the armature and magnet costs minutes. A second teardown costs another shutdown.
Quiet, full-current operation
New magnet faces, fresh coil, new contacts on all three poles. The contactor pulls in clean and holds silent, at a bundle price 21% below the parts alone.
