closed. If it takes significantly longer than 5 seconds, if it doesn’t click at
all and never closes, or if the switch is constantly closed and never opens,
replace the switch.
If the switch is not defective, unplug the 2
Brown
wires from the switch
and jump them together. Turn the stove on and wait 5 minutes. After five
minutes you should see 2 things:
1.
The room fan comes on.
2.
The ON/OFF light will quit blinking and be ON constantly.
If the 2 items listed above do not occur and the ON/OFF light keeps
blinking, check to make sure the
Brown
wires are inserted properly into
the Molex connector that plugs into the control board. They may appear to
be inserted properly, but sometimes are not connected to the pins on the
control board. Push the 2 Brown wires into the Molex connector to ensure
they are seated properly.
If they are inserted properly, use an OHM meter and check both
Brown
wires for continuity.
As a last resort the control board should be replaced. If this problem is
intermittent, it most likely is not the control board.
Remember: Once the stove is turned on, both fans come on for 30 seconds, and then
the room fan shuts off and goes into the Start-up Cycle. If the control board does not
sense the P.O.F. switch in the first 15 minutes, the stove will shut down and once all
fans shut down the #3 LED light will start blinking.
The Auger Motor
Auger Motor -
Located near the back-center of the stove and mounted to the Auger
Shaft. This 2-RPM motor rotates the Auger Shaft, which in turn feeds the fuel into the
Burn Pot. The Auger Motor rotates when the Auger Light is ON, the duration of the ON
and OFF cycle will vary depending upon which level has been selected using the Heat
Advance button, level 1 through level 5.
Assuming the diagnostic lights are not indicating a problem that has shut down the stove
and the auger is not jammed in any way, let’s focus on circumstances that could interrupt
power to the motor. Power (line voltage) is applied to the auger motor intermittently. If
the auger motor is not running when it should, check the following:
•
Check to see if the High Limit switch has tripped. This will prevent the Auger
motor from running.
•
Check the Fuse on the back of the control board, replace with a 120 Volt, 5 Amp
fuse, 5 MM x 20 MM fast acting fuse. First Generation Digital Control Boards
have 2 fuses, check the fuse labeled F1. (See Figure 9 on Page 71)
