TROUBLE SHOOTING GUIDE
Tools Essential for Trouble Shooting
1.
Furnace Installation and Operation manual
2.
Circuit Tester / Volt Meter
3.
Molex pin Extractor
4.
Volt Meter
STEP #1
ATTENTION: Before attempting any trouble shooting:
1.
Check your wiring to control box to insure proper polarity and grounding.
2.
Check flue for any blockage.
3.
Take time to clean burn pot and heat exchangers.
4.
If you have replaced the fan limit control, make sure the brass connector in
the middle has been removed or snipped
.
STEP #2
CONFIRM POWER TO CONTROL BOARD
Turn Main power switch from the “Stove Off” position to the “Draft Fan” position. If
the red indicator light comes on, there is power to the control board. If the light does
not come on check the following:
A.
Power Source (See Step #1)
B.
Fuse
C.
Burner Manual Reset – If the fuse is not blown and the reset button has not
popped out, inspect the Molex connection. Finally, using a voltmeter, check for
power at the power switch. If the meter indicates 115v and the light still doesn’t
come on, replace the control board.
STEP 3#
CONFIRM DRAFT FAN OPERATION
Be sure the main power switch is in the “Draft Fan” position. This will cause the draft
fan to operate at full power (115v). The draft fan will operate at 70 – 75v when pilot
draft switch is set at high. It will receive 60 – 65v in the medium position and zero
volts in the off position when furnace is not feeding fuel. You should be able to hear
the draft fan come to full speed. You can check movement of air by placing you hand
over the fire pot. If movement of air is not obvious, make sure that the shutter is
open.
STEP #4
INSPECT FUEL METERING CUP FOR BLOCKAGE
To inspect the metering cup, first you will need to empty the hopper. Reach down
through the hopper and rock the cup back and forth. The cup should mover ¼ of an
inch. If it does not move, something is jamming it. Sometimes the obstruction can be
removed by rotating the blade on the cup motor counter clockwise. If this doesn’t
work you will have to remove the cup motor and cup to remove the blockage.
