Delay in pellet drop

[Nobletango2186]

USSC model 6039. Replaced 3 button board to 4 button. Everything is working except now the auger has a 20 second delay after dropping pellets no matter what setting HR is on. ex: auger only turns about 1/4 turn, then it takes about 20 seconds until it turns again and the fire starts to go out. My other USSC stove turns like every 4-6 seconds. Any help would be greatly appreciated.

This the first time I ran the stove straight for over 24hrs. The glass was almost completely black and the burn pot seems to full to overflowing. I read in the manual that it comes set from the factory to burn corn,so does that mean something on the control panel needs to be set to burn pellets. In 24 hrs it used a little over one bag of ProPellets. Thanks in advance for the help.

USSC model 6039. Replaced 3 button board to 4 button.

What board did you replace with should have been 80507? USSC uses same board in many stoves they are just programed for that stove.

What is your agitator/pot stirrer doing is it running faster? Reason I ask is every 20 seconds sounds like stirrer speed. You could push Aux. down button set it to 9 and see if auger speeds up or stirrer speeds up.

Check your feed rates with the C Codes. Toggle through all the codes and write down what each reads, pay special attention to C2 and C3 the control feed rates should be 2.0 and 5.0.

6039 4 Digit Board C Codes
To adjust the operation constants, press the hold the MODE and AUGER DELAY buttons
simultaneously for 3 seconds. The display will show “C-1”. Use the HEAT RANGE UP or HEAT
RANGE DOWN buttons to change the constant number (see the list of vales below). When the
desired constant is displayed, press the ON button to toggle between viewing and editing the value.
While editing a parameter, use the AUX again to return to the constant number list. Press the OFF
button to exit the operational constants mode.
 C-1- Reset to defaults (hold mode and auger delay buttons for 3 seconds to reset all to
defaults)
 C-2- Fuel Lbs. Per hour HR 1 (0-6.5) - this is the fuel rate in pounds per hour for a heat
range setting of 1. The Default is 2.0lbs per hour.
 C-3- Fuel Lbs. Per Hour HR 9 (0- 6.5) - This is the fuel rate in pounds per hour for a heat
range setting of 9. The Default is 5.0lbs per hour. The fuel rates used between settings of 1
and 9 are linearly interpolated between the two settings.
 C-4-Agitator On Percentage HR1 (0-50) – this is the percent on time for the agitator for
setting of 1. The Default is 25%.
 C_5-Agitator On Percentage HR9 (0-50) – This is the percent on time for the agitator for a
setting of 9. The Default is 50%. The percent on time for the agitator used between
settings 1 and 9 are linearly interpolated between the two settings.
 C-6-Room Fan Level HR 1 (0-500) – This is the output level applied to the room fan for a
setting of 1. The Default value is 250/500.
 C-7-Room Fan Level HR 9 (0-500) – This is the output level applied to the room fan for a
setting of 9. The Default value is 370/500. The Room fan output levels used between
settings 1 and 9 is linearly interpolated between these two settings.
 C-8-Draft Fan Level HR 1 (0-500) – This is the draft fan output lever for a draft fan setting of
1. The Default is 230/500.
 C-9-Draft Fan Level HR 9 (0-500) – This is the draft fan output lever for a draft fan setting of
9. The Default is 270/500.
 C-10-Draft Fan Full On at Setting 9 (0-1) – If this parameter is set to 1 (default), the setting
for C9 is used for a fan speed of 8, and a value of 500 is used for a fan speed of 9. If the
parameter is set to 0, the setting for C9 is used for a fan speed of 9, and all remaining fan
speeds are set based on the interpolation between C9 and C8.
 C-11- Ramp Seconds for Increasing Level (0-300) – When the heat range setting is adjusted,
the control will ramp from the current setting to the target setting to avoid abrupt changes
in the outputs that could cause problems with the flame quality. The Ramp Seconds value
sets the amount of time to spend on each heat range setting as the current setting is
ramping toward the target. If the current setting is ramping down toward a lower target, the
ramp value is half the number. The default value is 90 seconds.
 C-12-Startup Minutes for Detection Warm Stove- (10-60) This is the amount of time the
control will wait for the stove to reach the warm temperature (110°F) after the stove

I did replace with the 80507. I will try your suggestion. I did run C codes and all passed

 

[Nobletango2186]

My agitator motor needs to be replaced. Part is currently in transit to me. This may be a stupid question but does the agitator need to be working in order for the auger to drop pellets faster?

No, when I burnt straight corn I would unhook agitator and use a deeper homemade pot.

What do you mean passed? Were all set at default settings? or are you talking about a board test? Run test and see what 4. does. Stove must be cold to test.

6039 4 Digit Control Board Test
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 then
press and hold the Off and Auger Delay buttons simultaneously for 3 seconds. To advance
through the test press the on key. If the Heat Range lLight is on during every test check
Hopper Switch Wires.
1. Exhaust Fan Output Test- The display will show “OUT1”. 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. Press the ON button to move
to the next step.
2. Room Fan Output Test – The display will show “OUT2”. The room fan is turned on full.
Press the ON button to move to the next step.
3. Agitator Output Test – The display will show “OUT3”. The Agitator motor is turned on
full. Press the ON button to move to the next step.
4. Auger Output Test – The display will show “OUT4”. The auger motor is turned on full.
The ON LED will be lit when the over temperature is in cool state. Press the ON button
to move to the next step.
5. Low Limit Switch Test – The display will show “IN 1”. If the stove is warm (above
110°F), the ON LED will turn OFF. If the stove is cool the ON LED will be on. Press the
ON button to move to the next step.
6. Thermostat Test – The display will show “IN 2”. If the thermostat input is closed, the ON
LED light will be on, otherwise it will be off. Press the ON button to move to the next
step.
7. Temperature Test – If equipped with an RTD sensor it measured the temperature and
will display in 0° F. Press the ON button to move to the next step.
8. AC Frequency Test - Displays the measured AC frequency in hertz followed by the letter
“H”.
This should read 59, 60, or 61H. Press the ON button to move to the next step

I did that as well and the auger turns on full. The reason I had to replace the 3 button was because the auger would not STOP turning so I bought a new one which is the 80507 4 button, now the auger takes the 20 seconds between turns to drop the pellets and the fire almost burns out before more pellets are dropped.

auger takes the 20 seconds between turns to drop the pellets and the fire almost burns out before more pellets are dropped.

If board test on 4. ran auger then should be wired right. But check Brown wire to agitator . Black wire from high limit switch to auger, red wire from board to high limit switch.

When you ran board test did the auger run at full speed? Also if you turn stove on then push and hold ON button does the auger continually run full speed as long as you hold button?

 

[ARC]

Can you test the auger motor, unplug stove unplug auger motor connect a old lamp cord to auger motor and plug that cord in, should run the auger motor at 4.1 revolutions per minute.

The auger runs continuously if I hold the on button. And yes when I ran the board test the auger ran at full speed. I am lost at this point...not sure what else to do to get the auger to drop pellets faster

 

[ARC]

what else to do to get the auger to drop pellets faster

Try going back to the C codes if C2 says 2.0 and C3 says 5.0 try increasing these numbers. If this does not work I would say you got a bad board. I have done the ABC to 4 button change on 4 stoves and they were all plug and play with no problems.

You could try to "jump" high limit switch unplug stove remove wires from high limit switch attach the two wires together with paper clip or jumper wire, tape so it does not touch stove, plug stove back in and try to start. I am wondering if high limit switch is bad and telling stove to go into shut down mode. You could also try "jumping" low limit switch only do one at a time so you can tell if one is bad.
