Troubleshooting the thermostat

We will start with the heating or cooling wall thermostat used in residences and commercial spaces.  
These thermostats are quite simple to troubleshoot if you have a situation where the heating or cooling unit does not work.  
You simply eliminate the thermostat.  If the unit works when you have bypassed the thermostat, the thermostat is the problem.  Below, we have a video demonstrating how to bypass a heating thermostat to determine if it is the problem.
