The CAT 246D skid steer loader is widely used across construction, agriculture, and landscaping industries. Known for its robust performance and powerful engine, it is a popular choice among operators. Recently, some users have reported issues with the air conditioning (AC) system, specifically when the AC stops cooling or works intermittently. This article summarizes the reported issues and suggests possible solutions based on user discussions.
Symptoms and Manifestation of the AC Problem
From user feedback, several common symptoms of CAT 246D AC issues have been identified. The most common problem is that the AC works fine initially but loses cooling power after a short period, leading to a rising cabin temperature and reduced comfort during work.
Another common symptom is that the AC switch operates normally, but there is no cooling effect at all. This issue can occur shortly after the AC is turned on, or sometimes the cooling stops suddenly after a brief period of working.
Potential Causes of the Issue
The AC issues with the CAT 246D are typically related to low refrigerant, compressor malfunction, or electrical faults. Regular maintenance, such as checking refrigerant levels and cleaning the condenser, can help prevent AC failures. If the problem persists, it is advisable to seek professional assistance for a thorough inspection and repair. Timely resolution of AC issues ensures optimal comfort for the operator and maintains the machine’s performance.

Potential Causes of the Issue
- Low Refrigerant Levels
One of the most common reasons for poor AC performance is insufficient refrigerant. Low refrigerant levels can prevent the system from cooling effectively. It is recommended to periodically check the refrigerant levels in the system and add refrigerant if necessary.
- Faulty AC Compressor
Another potential cause is a malfunctioning AC compressor. If the compressor fails, it will not generate enough pressure, leading to insufficient cooling or no cooling at all. In this case, the compressor may need to be repaired or replaced.
- Electrical Issues in the AC System
Electrical issues, such as poor connections or faulty sensors, can also lead to AC failure. It is suggested to inspect the electrical connections to the AC system to ensure they are tight and corrosion-free.
- Clogged or Dirty Condenser
A dirty or clogged condenser can reduce the AC system’s efficiency. It is important to regularly clean the condenser, especially in dusty environments.
- Check Refrigerant Levels
The first step is to check the refrigerant levels in the AC system. If levels are low, adding refrigerant according to the manufacturer's specifications can often resolve the issue.
- Inspect the Compressor and Electrical System
If refrigerant levels are fine but the AC still isn’t cooling, check the AC compressor to ensure it is operating properly. Also, inspect the electrical connections, including the AC switch and sensors, to rule out electrical faults.
- Clean the Condenser and Radiator
Cleaning the condenser and radiator regularly is essential, particularly when working in dusty conditions, to ensure proper airflow and cooling efficiency.
