Frequently Asked Questions

What does the A/C high pressure switch do on a Case 580K?

The high pressure switch protects the A/C system by cutting power to the compressor clutch if refrigerant pressure gets too high. On the 580K and 580SK, a faulty switch can cause the compressor to stop cycling or the A/C to stop cooling. Match the part number to confirm the right switch for your machine.

Why is my blower only working on high speed on a Case 580M?

When a cab blower only runs on the highest speed, the blower speed resistor is usually the cause. Broken Tractor carries multi-speed blower resistors for the 580M, 580 Super M, 580N, and 580 Super N. Replacing the resistor typically restores the lower fan speeds.

What is the difference between the high and low pressure switch on a Case backhoe?

The high pressure switch shuts the compressor off when pressure spikes, while the low pressure switch prevents operation when refrigerant is too low. Both protect the compressor. We carry each type for the 580 and 590 series, so confirm which one your system needs.

Will a rotary thermostat switch fit my Case 580 Super L?

Broken Tractor offers rotary thermostatic switches that fit 580L, 580 Super L, 580K, 580 Super K, 590 Turbo, and 590 Super L backhoes with cab A/C. Fitment can depend on the A/C setup, so match the part number or call the parts team at (800) 909-7060 to confirm.
