Description
Nobody likes sweating through a long day in the cab or having windows fog up when you need to see what you’re doing. When your tractor’s fan only works on high speed—or quits working altogether—your blower motor resistor has likely given up the ghost. This small but critical component controls your fan speeds, giving you the comfort control you need whether you’re dealing with a dusty harvest day or trying to clear frost off the windshield at dawn.
What You’re Getting
- Direct replacement resistor that restores all fan speed settings to your cab
- Heavy-duty construction designed for the continuous operation demands of farm work
- Proper electrical specifications to handle agricultural blower motor current draw
- Mounts in the original location with existing hardware and connectors
Built for Real Farm Work
This resistor fits a wide range of Case IH tractors from utility models like the 43 and 44 Series up through the big Magnum row-crop machines. Whether you’re running a compact tractor for chores around the farm or pulling implements with a 200+ horsepower machine, this part keeps your cab comfortable during those long days when the work just has to get done.
Made to Last
Blower resistors live a tough life—they’re constantly converting electrical energy into heat while sitting in an airstream that carries moisture, dust, and debris. This replacement uses heavy-duty resistor elements specifically designed for tractor service where the fan might run ten hours straight without a break.
Good to Know
Most blower resistors mount in the blower housing behind the dash or glove box area. The old one typically unplugs with a multi-wire connector and removes with two or three screws. Always disconnect the battery first and let things cool down if the blower’s been running. Test all fan speeds before putting everything back together, and if your resistor failed early, check your cabin air filter—restricted airflow makes the blower work harder and can shorten resistor life.
