Refrigerant Circuit Others
Compressor stuck Shortage of refrigerant Restricted liquid line Dirty air filter Dirty evaporator coil Insufficient air through evaporator coil Overcharge of refrigerant Dirty or parally blocked condenser Air or incompressible gas in refrigerant cycle Short cycling of condensing air High temperature condensing medium Insufficient condensing medium Broken compressor internal parts Inefficient compressor Expansion valve obstructed Expansion valve or capillary tube closed completely Leaking power element on expansion valve Poor installaon of feeler bulb Heavy load condion Loosen hold down bolts and / or screws Shipping plates remain aached Poor choices of capacity Contact of piping with other piping or external plate
Replace the compressor Leak test Replace restricted part Clean or replace Clean coil Check fan Change charged refrigerant volume Clean condenser or remove obstacle Purge, evacuate and recharge Remove obstrucon to air flow Remove obstrucon in air or water flow Remove obstrucon in air or water flow Replace compressor Test compressor efficiency Replace valve Replace valve Replace valve Fix feeler bulb Check heat load Tighten bolts or screws Remove them Choose AC of lager capacity or add the number of AC Recfy piping so as not to contact each other or with external plate
