New 2 ton american standard a/c unit with a noticeable delay in the compressor start in ref. to the condenser fan motor start ( appox .50 sec. delay ). System has a hard shut-off TXV, factory start cap. with potental relay, voltage good ( 240 vac 1ph). System operation ok, 13 deg. superheat, 12 deg subcooling. 76psig/226psi.
Any suggestions on why? Never had this happen before. The very first start up no delay. cycled several times with consistant compressor delay.
