As we discuss in this brief, the administrationâs reports to the court do not preclude the Legislature from assessing the measures identified by the administration and considering its own strategy for compliance with the court ruling based on its priorities.
The two most common causes of low head pressure at an air conditioner or heat pump compressor motor are: 1  Refrigerant under-charge, due to a refrigerant leak or improper charge.  TXV (TEV) malfunction, over-metering refrigerant.
1 Watch out: when an air conditioner or heat pump motor burns out the result is a costly contamination of the entire refrigeration system as burned lubricants and even shellac or coatings on motor windings will have been circulated through the refrigerant piping system.he effect of too much refrigerant in the system-overcharging, over-metering, or other high refrigerant pressure situations are detailed at EFFECTS of OVER CHARGING of REFRIGERANT. If your air conditioning or heat pump system has lost its cooling capacity or won't start see REPAIR GUIDE for AIR CONDITIONERS.
