The feed motor is powered by 12v DC current. After the stove or insert has started (out of "SS" mode), the feed motor runs constantly. Readings will be between 3v-12v depending upon the fuel table and the demand cycle for heat.
If the feed system was recently removed or a new one was installed prior to feeding problems
- Make sure the feed system is mounted correctly.
- The top of the motor bracket must be hanging on both of two upper hooks.
- The bottom of the feed system needs to be secured with the phillips screw.
- The gasket for the feed system must be under the motor mount and between the top of the feed tube.
- The depth of the auger spring must be set to a depth of 13" from the bottom of the motor mount when secured to the feed motor.
If you keep getting random error codes for 'AUGER JAMMED' but ONLY after the unit has started and achieved fire.
- Check the auger spring set screw is tight. If it is not loose, replace the optical sensor, SRV7034-038.
- If your feed auger spring is bent, replace it, part SRV7001-046
If you are getting a MIN FP TEMP Error Code: UNIT IS OUT OF FUEL OR CHECK FOR PROPER FUEL SETTINGS. THIS CODE WOULD DISPLAY ANYTIME THE FIRE GOT UNDER 500 DEGREES DURING ITS NORMAL RUN MODE.
- Confirm that your fuel setting is correct for the fuel you are using.
- Check the auger spring set screw, make sure it is tight.
- Check the collar set screw, make sure it is tight. If it is loose, verify that there is 13" of depth from the motor mount to the end of the spring and then tighten the set screw.
- If both of these set screws are tight and there is 13" of depth, remove the feed system from the feed tube, seal the top of the feed tube with a rag and run start-up with the feed system removed.
- With the feed system removed try to run the unit so that you can watch the rotation of the feed spring. It should be rotating CW with the spring pointed away from you. If the motor is rotating CCW or starts CW then switches to CCW, with the feed system pulled from the stove, replace the optical sensor, part SRV7034-038.
- Remove the vacuum hose from the drop tube and make sure there is no obstruction. If there is anything blocking, or partially blocking the inlet, clear it with some wire from a paper clip.
- Verify that you are getting at least 3v of power to the motor across the black and white wires in the harness, if you are, replace the feed motor, SRV7000-313.
Other Items to check when the unit is not feeding:
- Check the Door & Hopper sensors 7000-375: *Make sure the door & hopper lid is closed and the icons on the wall control are not displayed.
- Check over heat snap disc 230-1290: *This is located on the pellet drop chute. Is it tripped? Reset if needed. This will kill power to the feed system.
- Check the vacuum switch SRV7000-531: *Check for an error code or test the vacuum switch.
- Replace the optical sensor, SRV7034-038: *Replace this part if all previous checks are good.
- Replace the feed motor SRV7000-313: *Replace this part if all previous checks are good.
- Check the 10-pin harness for a loose pin or broken wire: *Replace the harness if broken. (SRV7034-191)
