Low Side Pressure Is Low & High Side Pressure Is High

Some possible causes of low side system pressure being to low and high side system pressure being to high include:

• Restricted refrigerant flow through refrigerant lines.
• Restricted refrigerant flow through expansion valve.
• Restricted refrigerant flow through fixed orifice tube.
• Restricted refrigerant flow through receiver-drier.
• Restricted refrigerant flow through condenser.
