Portillo said some of them just want him to fix whats broken and thats it.

There are multiple ways a thermostatic expansion valve (TXV) can become restricted.

A restricted filter drier will give the same symptoms as a restricted TXV, since it, too, is in the liquid line (see Figure 1). Some might answer that in the case of coil failure, its cheaper for the owner to replace the coil that has failed rather than replacing two coils.

The evaporator will have a tendency to ice up. As mentioned earlier, a system with a restricted metering device has the very same symptoms as a system with a liquid line restriction because of the TXV being part of the liquid line. WebA bad condenser can cause misfire and burning of the points. Service technicians often confuse an undercharged system with a restricted metering device, and adding refrigerant to a system with a restricted liquid line will only raise the condenser subcooling amounts to a level where the head pressure may elevate.
