Just wanted to update everyone and I noticed another member having cooling issues here

after I got 3 bad thermostats
2 from ab and 1 from lucky 8
my forth Tstat solved my cooling issue

there could be a bad batch of thermostats going around

even though I tested them in hot water and they opened at 195 however when installed the flow was very poor

All 180

Ya maybe there is a problem with the 180 tstats lately
