We have a 5510 King that when shut down the draft fan stays running and will not shut down. Also if turned back on the auger motor isn't feeding. Can anyone help or should we scrap it and go new?

What happens when you unplug stove and plug it back in, does the draft fan still run? Try running the test mode after stove has cooled off. Unplug stove plug back in then run the test. Pay attention to test 1 and 7.
Check the Thermistor to see if it is tight on the draft fan box and tightly plugged into the control board.
Check Pressure switch to see if wires are connected firmly.
If the test reveals nothing wrong then most likely you have a triac sticking on your control board it can be repaired if you are good at soldering, a new control board is around $575 for the 5510.
Remember always unplug stove before working around the control board.
PERFROMING AN INTIAL TEST
This test is used at the factory where the stoves are assembled to test the functionality of the control and the stove
before the unit is shipped. To perform this test, press and hold the OFF and AUGER DELAY buttons simultaneously for
3 seconds. To advance through the test, press any key unless otherwise noted in the test step.
1 Exhaust Fan Output Test – The display will show “drft”. The exhaust fan is turned on full then reduced to a level just
above the typical minimum pressure switch setting. The ON LED indicates whether the pressure sensor is detected.
If the pressure switch is not detected, the fan ramps to full on for two seconds then returns to the previously established
level if the pressure switch closes. If the Draft Fan Fuse is not blown and the fuse detection circuit is functioning,
the Draft Fan LED will be lit and the other three top row LEDs will be off.
2 Room Fan Output Test - The display will show “rfan”. The room fan is turned on full. If the Room Fan Fuse is not
blown and the fuse detection circuit is functioning, the Room Fan LED will be lit and the other three top row LEDs
will be off.
3 Ignitor Output Test - The display will show “ignt”. The ignitor motor is turned on full. If the Ignitor (AUX) Fuse is not
blown and the fuse detection circuit is functioning, the Aux LED will be lit and the other three top row LEDs will be off.
4 Auger Output Test - The display will show “augr”. The auger motor is turned on full. If the Auger Fuse is not blown
and the fuse detection circuit is functioning, the Heat Range LED will be lit and the other three top row LEDs will be off.
5 Hopper Switch Test – The display will show “hppr”. The “ON” LED is lit. If the hopper switch is open (lid is open),
the “HEAT RANGE” LED will turn on. If the lid is closed, the “HEAT RANGE” LED will be off.
6 Thermostat Input Test – The display will show “stat”. If the thermostat input is closed, the ON LED will turn on,
otherwise it will be off.
7 Flue gas Thermistor Test – The display will show the flue gas temperature in degrees F.
8 AC Frequency Test - Displays the measured AC Frequency in hertz (59-60) followed by the letter ‘H’.
9 Watchdog Reset – The watchdog timer is tested to ensure that the board can be reset. The message “BYE” is
displayed until the watchdog resets the board.
Check the Thermistor to see if it is tight on the draft fan box and tightly plugged into the control board.
Check Pressure switch to see if wires are connected firmly.
