Question about Heating & Cooling
If you have a volt meter, check to see if you have 24 volts coming from the thermostat on the yellow wire.
If you do, and it is set on emer heat, you have a bad T-stat.
It looks like it is wired properly.
If you have no meter, you could try changing the stat, I reccomend Honeywell or white rodgers.
Let me know if you eliminate the Tstat as the problem and we can go from there.
Chances are its the stat.
