Why is The thermostatic expansion valve is freezing up on your air conditioning unit?
The valve it's self may grow some ice on it sine it is common for TXVs to keep the suction pressure a little lower then a fixed orfice system would. When that pressure falls below 32 degrees at a saturated temperature then ice will start to grow on the first couple inches of the evap coil but should melt away on off cycle.

Where does the phial position for a thermostatic expansion valve?
The phial of a thermostatic expansion valve is typically positioned on the suction line downstream of the evaporator coil. It is important for the phial to be securely clamped to the suction line to accurately sense the temperature of the refrigerant leaving the evaporator.
Which component cosists of a thermal sensing element used to regulate the flow of liquid refrigerant into an evaporator?
Thermostatic expansion valve consists of a thermal sensing element that regulates the flow of liquid refrigerant into an evaporator based on the temperature of the refrigerant returning from the evaporator.
If the evaporator pressure does not change when heat is added or removed from the thermostatic expansion valve bulb the problem may be?
If the evaporator pressure does not change when heat is added or removed from the thermostatic expansion valve bulb, the problem may be due to a malfunctioning thermostatic expansion valve itself, which could be stuck or blocked. Additionally, issues such as low refrigerant levels or a refrigerant leak can also prevent pressure changes. Lastly, a faulty bulb sensing element or improper bulb placement may hinder the valve's ability to respond to temperature changes effectively.
