As your patient was told by her ObGyn, it is safe to use combined birth control pills and Mirena at the same time and this practice may be helpful with regard to the irregular bleeding, prolonged bleeding, cramping or pain that can be associated with Mirena in the first months after Mirena insertion.
RE: AC compressor cycling. IP: Logged. Message: I have an '03 QC 4.7 v8 and the a/c unit will cycle when it's set to defrost and high heat on the temp gauge, a/c off. I read a post last night that talked about pulling the a/c defrost fuse # 24 (on the my truck) during the winter months to keep the a/c from cycling.
The defrost timer eventually switches into defrost mode and supplies power to the defrost heater(s) to melt any frost that has accumulated on the evaporator (cooling) coil. The cold control contacts remain closed but since the defrost timer is no longer feeding power to that circuit, the compressor does not run.
