The New Holland LS170 skid steer loader is a popular piece of equipment, widely used for various tasks in construction, agriculture, and landscaping. However, like any machinery, it’s not immune to issues. One common problem that operators might face is a malfunctioning cab blower. The cab blower plays an essential role in keeping the operator comfortable by providing ventilation and air circulation inside the cab, especially during long hours of operation. When it fails, it can cause discomfort and distraction, affecting overall productivity. Let’s explore the potential causes of cab blower issues on the New Holland LS170 and how to fix them.
Symptoms of a Faulty Cab Blower
The cab blower on the LS170 is responsible for circulating air inside the operator’s cabin, and its failure is often evident when the air becomes stale, or the blower simply stops working. Common symptoms include:
Electrical Issues with the Cab Blower
One of the most common causes of a malfunctioning cab blower is an electrical issue. The blower relies on power from the machine’s electrical system, and any disruption in this can cause the blower to stop working. Common electrical problems include:
Fan and Motor Problems
Another common cause of cab blower issues is the fan or blower motor itself. Over time, the fan can accumulate debris, dirt, or other obstructions that block the airflow. This can cause the blower to run weakly or stop working altogether. Additionally, the motor could become worn out or damaged due to long-term use or exposure to harsh conditions.
To check for fan or motor problems, begin by inspecting the fan blades. Look for any signs of damage, debris, or obstruction that could be preventing the fan from turning properly. If the fan appears to be in good condition, test the motor by directly applying power to it (if possible) to see if it runs. If the motor is faulty, it may need to be replaced.
Clogged Vents and Filters
In addition to the blower itself, clogged vents and air filters can contribute to airflow problems. Dust, dirt, and other debris can accumulate over time, restricting airflow and causing the blower to work less efficiently. This issue is particularly common in machines that are frequently used in dusty or dirty environments.
To fix this, start by cleaning the vents and checking the air filter for any blockages. If the filter is dirty or clogged, it should be replaced. Regular maintenance and cleaning of the vents and filters can prevent this problem from recurring.
Addressing the Problem: Step-by-Step Guide
To effectively troubleshoot and fix the cab blower problem on the New Holland LS170, follow these steps:
As with any part of the machine, regular maintenance can help prevent future issues. Cleaning the vents and filters on a regular basis, checking the fuse and wiring periodically, and ensuring the blower motor is well-lubricated will help extend the lifespan of the cab blower. In addition, operators should be aware of the operating conditions—if you are working in particularly dusty or dirty environments, more frequent checks and maintenance might be necessary.
A simple example of how preventative maintenance can save money comes from the story of an operator using a Bobcat S650 skid steer. The operator regularly cleaned the machine’s air filter, and as a result, avoided clogging issues with the HVAC system, saving hundreds of dollars in repairs over the machine's lifespan.
Conclusion: Ensuring Comfort and Efficiency with a Properly Working Cab Blower
The cab blower problem on a New Holland LS170 may seem minor, but it can significantly affect the operator’s comfort and the machine’s overall efficiency. By understanding the symptoms and performing basic troubleshooting, operators can quickly identify and fix the issue. Regular maintenance and prompt repairs will ensure that the blower continues to function properly, keeping the cabin comfortable, and helping you stay productive throughout the workday.
Symptoms of a Faulty Cab Blower
The cab blower on the LS170 is responsible for circulating air inside the operator’s cabin, and its failure is often evident when the air becomes stale, or the blower simply stops working. Common symptoms include:
- No airflow: The most obvious sign of a problem is when the blower fails to turn on at all.
- Weak airflow: If the blower is running but the air pressure is low, it can be an indication of clogged vents, a failing motor, or an issue with the fan itself.
- Unusual noises: Grinding or rattling noises coming from the blower unit may indicate that the fan blades are obstructed or damaged.
- Inconsistent airflow: Fluctuating airflow can indicate electrical issues or a problem with the blower motor’s connections.
Electrical Issues with the Cab Blower
One of the most common causes of a malfunctioning cab blower is an electrical issue. The blower relies on power from the machine’s electrical system, and any disruption in this can cause the blower to stop working. Common electrical problems include:
- Blown fuse: The fuse for the cab blower may have blown due to an overload or short circuit. This is one of the simplest issues to check and fix.
- Wiring issues: Loose or corroded wiring can cause intermittent or complete failure of the blower. Inspecting the wiring connections to ensure they are secure and free from corrosion is a good first step.
- Faulty switch or relay: A malfunctioning switch or relay could prevent the blower from receiving power even if the fuse and wiring are intact.
Fan and Motor Problems
Another common cause of cab blower issues is the fan or blower motor itself. Over time, the fan can accumulate debris, dirt, or other obstructions that block the airflow. This can cause the blower to run weakly or stop working altogether. Additionally, the motor could become worn out or damaged due to long-term use or exposure to harsh conditions.
To check for fan or motor problems, begin by inspecting the fan blades. Look for any signs of damage, debris, or obstruction that could be preventing the fan from turning properly.

Addressing the Problem: Step-by-Step Guide
To effectively troubleshoot and fix the cab blower problem on the New Holland LS170, follow these steps:
- Check the fuse: Inspect the fuse that powers the cab blower. If it's blown, replace it with one of the same rating.
- Inspect the wiring: Look for any loose, frayed, or corroded wiring. Tighten or replace any damaged connections.
- Test the blower motor: Apply power directly to the motor to see if it runs. If not, it may need to be replaced.
- Clean the fan blades: Remove any debris that might be obstructing the fan’s movement.
- Check the air filter: Replace the air filter if it’s clogged or excessively dirty.
- Examine the switch and relay: If the blower still doesn’t work, test the switch and relay for proper operation.
As with any part of the machine, regular maintenance can help prevent future issues. Cleaning the vents and filters on a regular basis, checking the fuse and wiring periodically, and ensuring the blower motor is well-lubricated will help extend the lifespan of the cab blower.
