replaced old ADC 1 with newer ADC IV - all seems to go okay, so far - damper activating, compressor and fans going
took about 1 hour to drop from 74º to 34º in fridge and another 30 minutes to bring it down to 37º - seems reasonable?
woke up at 6 this morning and all still working fine, temps on target,
but the freezer/evaporator fan was running constantly until about 7:30 - that seemed odd, but it shut off by itself
two little iffy issues not addressed in installation instructions with unit:
new harness did not have wire to replace for old pink wire at refrigerator control switch - back-tracked old harness and that wire went to switch on damper control not used in ADC IV - not problem, i guess?
new harness does not have wires to connect to fast freeze wiring at freezer control cap tube - i checked my new wiring harness with photos of other new ADC IV harnesses and they all seem to match up - what this about?
THANKS A TON for all your help here
