TROUBLESHOOTING GUIDE

20

1.    The hopper is out of pellets.

Refill the hopper

2.    The air damper is too far open for a low feed 

       setting.

If burning on the low setting, you may need to close the 

damper all the way (push the knob in so it touches the side 

of the stove).

3.    The burnpot is not pushed completely to the 

       rear of the firebox.

Make sure that the air intake collar on the burnpot is touching 

the rear wall of the firebox. 

4.    The burnpot holes are blocked.

Remove the burnpot and thoroughly clean it. 

5.    The air inlet, the interior chambers, or exhaust 

       system has a partial blockage.

Follow all cleaning procedures in the maintenance section of 

the owner’s manual.

6.     The hopper safety switch has failed or hopper

         s open. 

When operating the unit, be sure the hopper lid is closed so 

that the hopper safety switch will activate. Check the wires 

leading from the hopper safety switch to the control panel 

and auger motor for secure connections. Use a continuity 

tester to test the hopper safety switch, replace if necessary. 

7.    The auger is jammed.

Start emptying the hopper. Then remove the auger motor by 

removing the auger pin. Remove 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. 

8.    The auger motor has failed.

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. 

9.    The Proof of Fire (POF) thermodisc has 

       malfunctioned. 

Temporarily  bypass  the  POF  thermodisc  by  disconnecting 

the two brown wires and connecting them with a short piece 

of wire. Then plug the stove back in. If the stove comes on 

and works, you need to replace the POF thermodisc. This is 

for testing  only. DO NOT LEAVE THE THERMODISC BY-

PASSED. Your blowers will never shut off and if the fire went 

out, the auger will continue to feed pellets until the hopper is 

empty if you leave the POF thermodisc bypassed.

10.    The high limit thermodisc 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 lo-

cate the high limit thermodisc. To test if the thermodisc is bad, 

you can bypass it as described previously for the POF ther-

modisc.

11.    The fuse on the control board has blown.     

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. 

12.    The control board is not sending power to the

         POF thermodisc or other auger system 

         components. 

There should be a 5-volt (approximately) current going to the 

POF thermodisc after the stove has been on for 10 minutes.
