Carrier 58MVB Error Codes 32&34

Hi All. New to the forum - thanks in advance for the advice. A few days ago my wife and I noticed that the house was heating fast and at high heat. Aside from being able to feel it being too high, the thermostat was reading 72 but set at 68. When checking the furnace, I got error codes 32 and 34. The pressure switches did not read any resistance and all hoses were in good shape. I plan on having a service technician come out soon but I was hoping to get an idea of what could be wrong before he comes. It seems to make sense that it gets stuck on high heat mode when heating, but what needs to fail for that to happen?
