Fixed an Unmounted TEV Bulb on a Woodway Restaurant Walk-In Cooler 08.20.26
A Woodway restaurant called with a walk-in cooler running warm and a sight glass that would not clear on a system installed by others. Four pounds of R-404A went in on that reading before a twenty-pound pressure drop turned up across the filter drier, pointing at a restriction rather than a low charge. Clay returned with the part, replaced the drier, and cleared the drop, but heavy flashing remained. Checking the expansion valve turned up a sensing bulb that had never been installed, leaving the valve wide open with no superheat control. The bulb was mounted, strapped, and insulated to the suction line and the valve began metering properly. Call 254-272-2714 for commercial refrigeration service. Texas TACLA89963C, R290 Certified.
