Question about Coleman Mach 15 Air Conditioner
Unit runs fine at night breaks curcuit and cuts off during heat of day
These units should run in higher ambient conditions within limits. If your unit shuts down with an ambient temperature of 95°F there is a possibility that the system may have a slight over charge of refrigerant in the system or a slight undercharge. This can be easily checked under running conditions by checking the superheat of the gases returning to the compressor. You may also want to check the current draw and the voltage supply during these conditions that are causing the system shut down.
