How to Repair Excavator Air Conditioning Failure


If you are an excavator owner, it is very common for the excavator air conditioner to malfunction during daily use. At this time, what we need to do is to find professional maintenance personnel to repair it as soon as possible. Today, we will share some tips on repairing excavator air conditioning failures. We hope it will be helpful to you.

There are three main causes of common air conditioning failures:

  1. Insufficient air conditioning refrigerant;
  2. Excessive dust in the air conditioning filter;
  3. Failure of the excavator air conditioning system.

First, we can check whether the air conditioner refrigerant is sufficient. If it is insufficient, it needs to be added in time. Secondly, check whether the air conditioning filter is clean. If there is too much dust and debris, the cooling effect of the air conditioner will be greatly reduced.

The following are the detailed steps for replacing the excavator air conditioning filter element:

Step One: Find the Excavator’s Air Conditioning Filter

The air conditioning filter of the excavator is usually located inside the excavator body, and the internal cover needs to be removed first. In this location, you can find the fuzzy screen, which is the air filter that needs to be replaced.

Step 2: Remove dust and dirt from the surrounding area

Before removing the air conditioning filter element, you need to remove the surrounding dust and dirt to prevent dirt from adhering to the replacement filter element when replacing filter element. If necessary, use rubber gloves to protect hands from dust and dirt.

Step 3: Remove the old air filter

Now you can remove the old air filter. Tap gently from around to make sure all the dirt is loosened and falling off the filter element. Handle old air filters with care and avoid suddenly dropping or throwing them away.

Step 4: Install the new air filter

Before replacing the excavator air filter, please purchase a new air filter that is suitable for your excavator model. Insert the new air filter into the filter slot and press down to make sure it is securely in place.

Step 5: Clean up other parts

After installing the new air filter, other parts need to be cleaned to ensure that the inside of the excavator is clean and fresh. This allows the air filter to filter air more effectively, resulting in better air quality and longer filter life.

For excavator air conditioning failure repair, you first need to clean and inspect the air conditioning compressor, condenser, evaporator, and other major components to see if there is any damage and whether they need to be replaced. Subsequently, the maintenance personnel also need to check whether the air conditioning fan is working properly. If the fan is found to be damaged, it needs to be repaired or replaced. At the same time, you also need to check whether the connection between the air conditioning temperature controller and the electrical system is normal.

Finally, after the above steps of maintenance, we need to check whether the excavator air conditioner can work normally. If everything is normal, then the repair task is completed.
