What to do if my Harman Super Magnum Coal Stoker Stove won't turn off?
- A
  andrew84Aug 13, 2025
  If your Harman Stove won't shut down when turned to 'OFF', it could be due to several reasons. First, the shut-down sequence requires a minimum feed time until the ESP cools. Second, the ESP may be dirty or failed, in which case you should remove and clean the probe. Finally, ensure the mode selector is truly in the 'OFF' position; the status light will turn off when the knob is correctly positioned (unless there is a 3 blink error code.)

  If your Harman Stove doesn't respond when plugged in, there are several potential causes. First, check the circuit breaker at the service panel to ensure there is current to the outlet. Second, inspect the power cord and connection for defects, and re-connect or replace the power cord if necessary. Also, check the fuse on the circuit board and replace it if defective. Finally, the circuit board itself may be defective and require replacement.

  If the fire is out but the grates are full of fuel in your Harman Stove, consider these possibilities: * The combustion blower restrictor might be closed, so re-set it using a draft meter. * Ensure the combustion blower is correctly positioned in its mount. * There may be ash build-up under the grates; remove the grates and clean the air chamber. * The starting process might have failed; follow the start-up procedure. * The ESP may have failed; if the temperature on the DDM reads abnormally high when the stove is cold, replace the ESP.

  If the fire is out and there's no fuel on the grates in your Harman Stove, consider the following: * Check the hopper and fill it with fuel if it's out. * Avoid loading wet coal into the hopper, as it can cause bridging. * Empty the hopper and search for any foreign object obstructions. * With the hopper empty, examine the feed throat for obstructions. * Verify the operation of the motor, pusher arm, and pusher block for any feed system malfunctions.

Why is my Harman Super Magnum Coal Stoker Stove distribution blower not operating?
- A
  anthony70Aug 28, 2025
  The distribution blower in your Harman Stove might not be operating because the room temperature demand has been met, causing the blower to stop. Alternatively, the distribution blower will not run until the ESP senses a high enough temperature to ensure that the discharged air is warm, which means the ignition was unsuccessful.

Why is there unburned coal in the ash pan of my Harman Stove?
- N
  Nicholas WilsonSep 1, 2025
  If you find unburned or partially burned coal in the ash pan of your Harman Stove, it could be due to black rocks in the coal, so try different coal. Alternatively, the feed rate might be too high, so set the feed adjuster to a lower setting.

Why is coal pushing out the sides of the grate frame on my Harman Stove?
- T
  Timothy DicksonSep 5, 2025
  If coal is pushing out the sides of the grate frame in your Harman Stove, it is likely due to clinkers in the ashes restricting the flow of fuel over the burn grates. Re-set the restrictor using a draft meter to resolve this issue.

Why are there excessive fines in the fines tray of my Harman Stove?
- R
  Richard JonesSep 8, 2025
  Excessive fines in the fines tray of your Harman Stove can be caused by a dirty coal supply, so try different coal. It could also be due to a feed restriction causing grinding; remove coal from the hopper and check for a foreign object or large piece of coal. Also, the fines scraper adjustment might be off; re-adjust the scraper.
