Problem 3: Winnebago Rialta Poorly designed Air conditioning Compressor

As the title suggests, the air conditioning compressor may only be particularly poorly designed in Rialta. We will specifically discuss the two issues with the Rialta AC in our discussion.

What Causes the Rialta AC issues?

There are two reasons why the Rialta ac is subjected to many complaints. Unfortunately, Winnebago overflows the system with the incorrect number. 

They overfilled Freon with erroneous numbers. They put 48 oz of freon in it rather than 39 oz. One of the main causes of the Rialta compressor failing is an inaccurate freon level. 

Another factor contributing to the failure of the Rialta ac compressor is that VW altered its design in 2011. The design was not as expected as it should be. This newly redesigned compressor was not working as expected and was the reason for the failure.

Besides these two manufacturing faults, there are common problems you may face with the Rialta AC. For example, the AC is not cooling, or there is too much dust coming out of the AC.

In addition to the two manufacturing faults we have described earlier, you may face some other issues. However, Winnebago Riata has erased its inefficiency by changing the inaccurate amount of freon and replacing the faulty redesign compressor. 

The other problems include the ac not cooling properly or too much dust coming out of the ac. If you have these issues, you must first look for lack of coolant and a dirty filter.

If you have to change the compressor, the cost of replacing the compressor is somewhere between $1000 and $3000. If only the filter has to be changed, then the cost of the filter can be up to $20. In addition, the labor cost will be added if a mechanic does the job.
