TECH TIPS DID YOU KNOW? — The expansion valve is a refrigerant metering device that creates a temperature/ pressure drop. It also divides the system into two zones — high pressure and low pressure. The most common block valve failure is loss of gas charge inside the power element head. Plugged-up expansion valves cannot be flushed out and must be replaced. When replacing a capillary type expansion valve, make sure the capillary coil or bulb is properly attached to the outlet side of the evaporator line and well insulated with prestite insulation tape.
