Hello, I have a king ashley 5500 m in my garage turned it on,combustion motor ran ignighter doesnt work and auger motor as well. Everything worked fine when shutdown last season. Was wondering if there was a fuseable link between that and control board? Thanks for any information.

There are fuses on the back of the control board. Which control board do you have the older ABC control board or the newer 4 button control board.
One of the first things stove does is checks for vacuum if it does not find it ignitor will not come on auger will not feed pellets . Step 1 in either test checks vacuum. No. 1 reason bad vacuum is dirty exhaust. Check exhaust for birds nest or bee hive. Running through the entire test will tell you if all motors are working.
Run a factory test:
If 4 button board run this test.
PERFORMING AN INITIAL 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 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.
If ABC board run this
5500M/5500XL ABC BOARD TESTING PROCEDURE
To run this test the UNIT MUST BE COOLED OFF. Power up the unit by plugging in the power
supply cord to the back of the unit. Press the on button and the circuit board display will show a “2”
and a “0” or a “1” and “5”. When the display clears you can start the test.
Step 1: Press and Hold down the A and B buttons at the bottom of the board until the display shows
an “0” and a “1”. This steps checks the Exhaust Blower and Vacuum Switch. Check to see if the
Blower is running and if the Red LED is on above the A button. Open the door and see if the LED
goes off; shut the door and make sure it comes back on. If the A is not on in this step check the
gaskets on the door and clean the units exhaust blower and ash cleanouts Vacuum Issue. If so, Press
the ON button to go to the next step.
Step 2: Display will show an “0” and “2”. This step checks the room blower. Check to see if the
room fan is running. If so, Press the ON button.
Step 3: Display will show an “0” and “3”. This step is not for this unit. Press ON
Step 4: Display will show an “0” and “4”. This step checks the Auger Motor. With the hopper lid
closed, the auger motor should be running. If so, lift the lid to check the micro switch mounted on
the right side of the hopper; the motor should stop. Close the lid to make sure that the motor comes
back on. If so Press the ON button.
Step 5: Display will show an “0” and “5”. This step checks the igniter. If the board skips this step,
something is wired wrong or wires are missing. Do not skip this step. Check to see if the Igniter is
working and they can see it is glowing. If so have them Press the ON button.
Step 6: Display will show an “i” and “1”. This step does not pertain to this unit press the ON
button.
Step 7: Display will show an “i” and “2”. This step checks the Thermostat Plug. Make sure that
the LED (Red light) over the A button is on. If so, Press the ON button to go to the next step.
Step 8: Display will show a numerical value. This is the room temperature measured at the
thermistor attached to the exhaust housing. The displayed temperature should be close to the
room (ambient) temperature. NO temp reading (00) thermistor disconnected from the board
or bad board. Press the On button to go to the next step.
Step 9: Display will show the Frequency of the A/C input voltage. Display should show a 59, 60,
or 61. If so, Press the ON button to go to the next step.
The display will show a “2” and a “0” or “1” and “5” as it did when it first powered up. The
unit will turn off.

Main reason for loss of vacuum are:
1. Dirty/plugged exhaust path
2. Door gasket
3. Cracked or plugged vacuum switch hose
4. Hopper gasket
5. Weak/failing Exhaust motor
6. Failing vacuum switch
