Can a Bad Compressor Cause High Head Pressure?
Some of these, such as a bad TXV

TXV

A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in vapor-compression refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the refrigerant that ...

Can a bad compressor cause high pressure?

Symptoms for an inefficient compressor are high suction pressures and low discharge (head) pressures. If the compressor is inefficient, the evaporator cannot handle the high heat load due to a decreased refrigerant flow rate and the conditioned space temperature will start to rise.

What is the most common cause of high head pressure?

Bad Fan Motor

This is actually the most common issue that causes high head pressure. You can have a bad fan motor due to a few different reasons. Your fan blades naturally wear down over time. The process of them wearing down can be expedited by debris finding its way into your air conditioner's outside unit.
