I just had replaced my home central AC and Furnace with New Amana 4 ton
18 SEER ASX18 and 95% AFUE GMVC95 Distinction Unit.
AC stays at Stage 1 and does not go to stage 2. even after several hours.
it gives the code flashing C1 and 12 alternate.
once temp get cold enough and condensor stops the code come as F7
Could any one tell me what is the fault?
Thanks for the Help
