TROUBLESHOOTING GUIDE

When your stove acts out of the ordinary, the first reaction is to call for help. This guide may save time and money by en-

abling you to solve simple problems yourself. Problems encountered are often the result of only five factors: 1) poor fuel; 

2) poor operation or maintenance; 3) poor installation; 4) component failure; 5) factory defect. You can usually solve those 

problems related to 1 and 2. Your dealer can solve problems relating to 3, 4 and 5. Refer to diagrams on page 20 to help 

locate indicated parts.

For the sake of troubleshooting and using this guide to assist you, you should look at your heat level setting to see which 

light is flashing.  

1.    Airflow switch hose or stove attachment pipes    

       for hose are blocked. 

Unhook air hose from the air switch and blow through 

it. If air flows freely, the hose and tubes are fine. If air 

will not flow through the hose, use a wire coat hanger to 

clear the blockage. 

2.    The air inlet, burnpot, interior combustion air 

       chambers, combustion blower, or exhaust 

       pipe are blocked with ash or foreign material.      

Follow all clearing procedures in the maintenance sec-

tion of the owner’s manual.

3.    The firebox is not properly sealed.

Make sure the door is closed and that the gasket is in 

good shape. If the ash door has a latch, make sure the 

ash door is properly latched and the gasket is sealing 

good.  If  the  stove  has  just  a  small  hole  for  the  ashes 

to fall through under the burnpot, make sure the slider 

plate is in place to seal off the firebox floor.

4.    Vent pipe is incorrectly installed.

Check to make sure vent pipe installation meets criteria 

in owner’s manual.

5.    The airflow switch wire connections are bad. 

Check the connectors that attach the gray wires to the 

air switch.

6.    The gray wires are pulled loose at the Molex 

       connector on the wiring harness. 

Check to see if the gray wires are loose at the 

Molex connector. 

7.    Combustion blower failure

With the stove on, check to see if the combustion blower 

is running. If it is not, you will need to check for power 

going to the combustion blower. It should be a full cur-

rent. If there is power, the blower is bad. If there is not, 

see #8. 

8.    Control board not sending power to combus-

       tion blower.

If there is no current going to the combustion blower, 

check all wire connections. If all wires are properly con-

nected, you have a bad control board.

9.    Control board not sending power to air 

       switch. 

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

to the air switch after the stove has been on for 30 sec-

onds. 

10.    Air switch has failed  (very rare).

To test air switch, you will need to disconnect the air 

hose from the body of the stove. With the other end still 

attached to the air switch, very gently suck on the loose 

end of the hose (you may want to remove the hose en-

tirely off the stove and the air switch first and make sure 

it is clear). If you hear a click, the air switch is working. 

BE CAREFUL! TOO MUCH VACUUM CAN DAMAGE 

THE AIR SWITCH.
