3.
Ruptured Sensing Bulb If the sensing tube ruptures, the valve will remain closed.
4.
Sensing Bulb Loose If the sensing bulb works loose from its proper location on the evaporator output line, the valve will
remain open and flood the evaporator with refrigerant.
If it is determined that the valve is faulty, it must be replaced with another valve of exactly the same capacity and type. It
requires no adjustment.
EVAPORATOR CORE
This unit is very similar to the condenser, both in type of construction and in its trouble-free operating characteristics. When
checking this component, make sure that:
The air flow through the core is in no way obstructed by dirt, etc. clogging the fins of the core.
The sensing tube of the thermostatic control switch is in its proper place inside the evaporator core.
