King 5502 Powers on but doesn't feed

[DonnieVT]

Hi,

We have a King 5502M that got a new auger and blower fan last winter, the stove ran great when we last used it in the spring.
Now when we turn it on all we hear is that initial draft fan and nothing else happens, just that fan runs.
When we turn it off the lights on the board act as if it's powering down but it never does, that draft fan just keeps running.
There are no error codes displaying and I've tried the factory reset on the board a few times.

Bad board? Any help is appreciated.

Welcome to the forum. A few questions if you don't mind .
Is the stove on a Surge Protector?
Does the stove turn itself off in 15 min. or so when it does not fire up?
Do you have the manual?
Does the igniter get hot?
Is the stove clean from the door to the exhaust termination?

As johneh stated stove will run for 15 minutes before it finds fault and after you push off it will run another 15 minutes even if there has been no fire. I would first suspect that hopper switch is not working. Note that some 5502M do not have a hopper switch and some have been removed. Run the following test and tell us what happens, Pay special attention to 4 , 5 and 7. Manual attached if you don't have one.

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 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.

It isn't right now, it's been unplugged most the season.
it does not, it just runs the draft fan at a constant speed.
I don't but I believe it can be found online.
The igniter does not get hot.
The stove is clean.

Edit; I finally got an Error 3.

Thanks for helping out.

I have this working, I went outside and checked the exhaust venting and there was a blockage.
After I removed that it fired right up the first attempt.

The igniter does not get hot

If it is dropping pellets and the igniter does not get hot
check the wiring and check igniter circuit . Check for power to the igniter
Black and gray wires
