Match the part number on your old controller to confirm fitment before ordering.

Will the cab AC controller fit a Komatsu PC200-7?

Yes, the 20Y-979-6141 cab AC controller is listed to fit the Komatsu PC200-7 and PC200LC-7. The same controller also covers the PC210-7, PC220-7 and PC230-7 and their LC versions. Fitment can vary by serial number, so check the part number on your existing unit or confirm with the Broken Tractor parts team.

What does the cab AC controller do on a Komatsu excavator?

The cab AC controller is the module that controls cab climate and air conditioning output on Komatsu excavators. Broken Tractor carries it as a replacement for PC-series crawler excavators from the PC160 up through the PC1250, as well as several PW-series wheeled excavators.

Does the Komatsu PC1250-8 use the same AC controller as the PC-7 series excavators?

Yes, the 20Y-979-6141 cab AC controller is listed for the PC1250/1250LC-8 as well as many PC-7 series machines, including the PC300-7, PC350-7 and PC750-7. Because one controller covers so many models, the best way to confirm you have the right one is to match the part number on your current controller.

How do I make sure I order the right controller for my Komatsu excavator?

Start by comparing the part number on your existing controller to 20Y-979-6141, then check that your machine model is on the fitment list. Some Komatsu excavator parts change by serial number, so if anything does not match or the label is unreadable, call (800) 909-7060 and have your model and serial number ready.
