I have 2008 Cat 305 C Cr min excavator ac not keep cab cool when it get above 90 , anyone else had this problem ? any suggestions ? Thank you
I believe most utility excavators have a Photo eye up in the monitor housing that monitors the the inside temp. If that eye is no longer functioning it will allow the temp to climb and not cool down the cab. Also check the condenser to see if the fans are keeping it cooled down. Just my 2 cents.
