Went on a call today where the high pressure switch was short cycling the outdoor unit. Coil was iced up and capillaries iced cleat to TXV. Suction line iced line clear out to outdoor unit. I looked at the txv sensing bulb and it was mounted vertical with the capillary coming out of the bottom. I checked the coil paperwork and it said bulb must have capillary coming out of the top of it. Has anyone else experienced such a thing, and did flipping it over solve the issue? After I thawed the coil and switched the bulb around I fired it up and had sub cool reading of 11 deg. This was in range with manufacturers chart- within 2 deg. I would appreciate any feedback.
