Does stove need to be cleaned, does fire look normal on start up? If normal looking fire:

First thing to check would be the low limit switch, follow blue wire from control board it will take you to low limit switch. Unplug stove, unplug both wires from low limit switch, connect the two wires together with paper clip or jumper wire, tape connection, plug stove back in and try to start stove. If stove starts and run clean switch front or replace switch if needed.

I'm new to pellet stoves so bear with me. The blue wire runs to part number 80599. When I jump the wire and plug in the stove the exhaust blower starts immediately without turning on the stove. When I turn on the stove pellets start feeding and the stove lights. Good flame and room fan comes on after stove warms up.

When I unplugged the stove and put the ohmmeter on the sensor (80599) there was no continuity. After the test I unplugged the stove, unplugged the jumper and, while the stove was still hot, put the ohm meter on it again. While hot there is continuity.

While hot there is continuity.

This is correct it is called a low limit snap disc. When cold it is normally close/NC which means off no continuity no flow of electricity. When heated to 140 F it Opens ie opens the circuit has continuity and electricity flows through it to the auger. When shutting stove down it stays "open" until it reaches 120 F and then closes and stops the auger. Sometimes the face gets dirty and stops working. More often the snap switch goes bad and stops working or works intermittently or doesn't "open" until a higher temperature is reached. If "jumping" the wires worked you should try cleaning the face of the switch if stove does not run properly after cleaning then replace switch. The switch cost between $15-20 so you might just want to buy one and if you don't have to replace the old one you will have a spare.

Took the switch out and it was covered with a thick layer of carbon. Took a picture of the face to pick up a new one and put it back in. We'll see how it works. There is another sensor on the other side above the room fan. This one has continuity while cold and I checked it while the stove was hot and it still had continuity. I'm guessing that this one is the high temp limit switch. Stays close until temperature exceeds a certain point.
Thanks for your help.

Correct

on the sensor (80599)

Order the low limit switch by part number as long as it is a 80599 it will work even if the advertisement does not quote your stove.
