Overview
A hands-on diagnostic fix for the well-known A/C freeze-up issue on Massey Ferguson 4700-series tractors, focused entirely on repositioning the evaporator temperature probe. The creator explains why bypassing the probe switch makes things worse, walks through his trial-and-error testing process with pressure gauges and a vent thermometer, and gives a target cycling range of roughly 45-50°F. Most useful to owners already wrestling with this specific problem.
Posted by the DLH Farms channel; the creator describes himself as a non-owner doing repair work on a neighbor's tractor, suggesting a practical hobbyist or small-operation perspective rather than a professional shop or dealership.
