I have a Coleman Presidential II in my mobile home and it is summer time and I have my thermostat set to 76 and my unit keeps running even though my the temp is showing it is 72 in the house
I replaced the thermostat and it continues to run past the temp setting. What part in the Coleman unit do I need to replace to solve this problem?

It could possibly be in the unit but my first guess would be in the tstat or the wire. If the compressor contactor was sticking the coil would freeze because I don't think the blower would continue to run. Check the wire near the unit for rodent damage or simply dry rotted. Therefore the wires are touching each other and not shutting off. Also be sure your tstat is not overshooting the set point because it is trying to get to your humidity set point. This is referred to as temperature droop. Also verify it does not have a minimum run time. Good luck
