Arrived at location on 6/29/21 - Found high pressure switch stuck open because the condenser coil was blanketed with dirt. I chemically cleaned the condenser, but the pressure switch wouldn’t reset. I replaced the switch and the condensing unit now runs. I also brushed off the evaporator coil, because it was also covered in dirt. Cooler temp is coming back down but it will take a while to bring it down to set temp because of the warm product inside.
