Hello. My name is XXXXX XXXXX I'll do my best to help. Troubleshooting often requires meters and test equipment. Let's get started and see what we can do.
What is the model on your furnace. It will be on a label inside of right hand panel?
You can often use other thermostats with these furnaces but sacrifice the modulating feature of the gas valve by doing so.

My recommendation is the RHC-TST412MDMS. It is a true modulating thermostat. You could use any 2 stage thermostat, you would not be as efficient as the modulating thermostats. Here is a link and you can also Google search to find best price. http://www.amazon.com/Rheem-RHC-TST412MDMS-Touchscreen-Modulating-Programmable/dp/B008O008SW
