I can’t figure this thing out. Here’s the situation. The thermostat is a Ritetemp 6022 and no matter what I do to the damn thing it will not bring the temp in the house past 65 degrees. The wires are correct. The installation guide tells you one way to set the jumpers, the back of the cover for the jumpers tell you another. I’ve tried both. I’ve reset the thing numerous times. Should I be trouble shooting the furnace? It’s gas by the way. Thanks for any suggestions.

I had a very similar problem last week. Turned out I had a 10" crack in the heat exchanger. Major failure, had to set a new unit. But the unit was about 18 years old.

I wouldn't know a heat
I wouldn't know a heat exchanger if it hit me on the head. It may be time to call in a pro.
It's the thing in the furnace
It's the thing in the furnace that transfers heat from the flame and combustion gases to the air that is circulated throughout the house. Think of it as a radiator of sorts. Your flame/gas is inside and the fan circulates air outside. That is a bit of an oversimplification, but that's essentially what it is doing.
I am reading from the following:

Could this be caused by the reprogrammed Energy Star program?
I saw that and thought it might be it but once you put in custom settings it shuts that program off and you have to use a pen or paper clip to push this very small button to turn it back on.
What does the thermostat say it's set at? If it keeps changing its set point to 65, that's probably the "default" program in the unit doing that. If it still says it's set at, say, 70, but the furnace shuts off when it reaches 65, then something else is wrong.
Note that with that sort of thermostat it will reset to the default program every few hours if you just use the up/down buttons to set temperature. Press the HOLD button first ("HOLD" should come on on the display) and then the up/down buttons will be "permanent" in their effect.
I'm going to give you the
I'm going to give you the same suggestion I did last week on a similar problem. Go check your filter. A clogged filter will restrict airflow enough that the overheat sensor on new furnaces turns off the gas. The blower will run and run but the gas will only cycle on and off.
BTW, after giving this suggestion last week. I woke up to a cold house and a constantly running furnace. I check the air coming out of the vents and it was cold/cool so I went down and changed the filter and I had warm air in a couple of minutes.
*Update*
After hours of playing around with that thermostat I decided to give a new one a try. And what do you know, it worked. Well, it worked until the outside temp fell to below freezing, but that's a different story. Thanks for all the suggestions.
