TROUBLESHOOTING GUIDE

22

1.    Fuse on control board blew.

Remove the control board. On the back, there is one fuse. If 

it appears to be bad, replace it with a 5 Amp 125 Volt fuse. 

Plug the stove back in and try to run the unit.

2.    High limit switch has tripped or is defective.

Wait for the stove to cool for about 30-45 minutes. It should 

now  function  normally.  If  not,  use  the  owner’s  manual  to 

locate the high limit thermodisc. To test if the thermodisc is 

bad, you can bypass it as described previously for the POF 

thermodisc.

3.    Bad auger motor.

Remove the auger motor from the auger shaft and try to run 

the unit. If the motor will turn, the shaft is jammed on some-

thing. If the motor will not turn, the motor is bad.

4.    Auger jam

Start by emptying the hopper. Then remove the auger motor 

by removing the auger pin. Remove the auger shaft inspec-

tion plate in the hopper so that you see the auger shaft. 

Gently lift the auger shaft straight up so that the end of the 

auger shaft comes up out of the bottom auger bushing. 

Next, remove the two nuts that hold the top auger biscuit in. 

Then rotate the bottom end of the auger shaft up towards 

you until you can lift the shaft out of the stove. After you 

have  removed  the  shaft,  inspect  it  for  bent  flights,  burrs, 

or broken welds. Remove any foreign material that might 

have caused the jam. Also, check the auger tube for signs 

of damage such as burrs, rough spots, or grooves cut into 

the metal that could have caused a jam.

4.    Loose wire or connector

Check all wires and connectors that connect to the auger 

motor, high limit switch, and the Molex connector. 

5.    Bad control board

If the fuse is good, the wires and connectors check out 

good,  and  the  high  limit  switch  did  not  trip,  test  fir  power 

going to the auger motor. If there is not a full current going 

to the auger motor when the fuel feed light is on, you have 

a bad control board.
