TROUBLEShOOTING & FAq
The 50F Furnace is very trouble free in operation when properly maintained and quality fuel is used. When
the furnace fails to operate properly, use the following to troubleshoot.
1. No fuel is being dispersed.
Solution:
Insure the auger tube is primed. If it is, check for jams
or that the lid is closed (the micro switch on the hopper will
not let the auger run if open). If not, press manual feed to
prime the auger.
2. My furnace keeps overloading the burn pot.
Solution
: If burning corn check the moisture content of your
corn. It should be 16% or less. also make sure you are
using clean corn. Otherwise this is mainly caused by
improper combustion (See damper adjustment section of
the Operations Manual). Besides the damper adjustment,
there are several areas that can have an effect on the
combustion process. check all gaskets, doors and door
latching systems for air leaks. any leaks in these areas will
negatively affect the burn process and cause the pot to
overload.
3. My furnace isn’t burning and the control is
displaying LOSS of FLAME.
This message indicates the
Proof of Fire switch no longer senses a flame in the firebox
area of the furnace. What caused the furnace to go out?
a. Fuel stopped feeding.
b. Fire went out due to fuel overloading the fire pot.
c. The Proof of Fire switch is defective.
d. The Proof of Fire switch is defective.
e. Unit ran out of fuel.
Solution:
check hopper for fuel. Press the Prime button to
ensure fuel is being dispersed. check fire pot to ensure
proper installation and re-light the furnace.
4. My furnace isn’t burning and the controller is
displaying LOSS of vACUUM.
This message indicates
that the Sail switch no longer senses a vacuum in the fur-
nace.
a. The door of the unit was left open longer than 90 seconds.
b. The ash pan door was left open longer than 90 seconds.
c. Switch is defective.
d. Intake air or exhaust path obstructed.
e. Seals need replacing.
Solution
: Check inner door gasket and ash pan gasket to in
-
sure good seal. check combustion air path for obstruction.
check to see if combustion blower is still operating by at-
tempting to restart.
5. My furnace isn’t burning and the controller is dis-
playing LOSS of POWER.
This means the power was
interrupted at some point and the unit shutdown.
Solution
: Restart furnace if power has been restored.
6. I turned the furnace on with the On/Off switch
and nothing happens.
Solution
: First check to see if the Furnace is plugged in and the
receptacle has power to it. check the fuse on the back of
the control board. Replace with a 10 a fuse.
7. I turned the furnace on with the On/Off switch
and the board lights up and the fans come on,
but the pot doesn’t go into self-clean.
Solution:
Unit may be waiting for the sail switch therefore check
for proper seals and that the fire door and ash pan are
securely closed. actuators will not move unless vacuum is
detected.
8. Why is my glass dirty?
normal operation of your Fahrenheit Technologies Inc. Fur-
nace will produce a light build-up on the glass that wipes
off with a dry paper towel. However extended burning on
the low setting only will produce a light tan color. These
types of build-ups on the glass are normal. a heavy black
build-up on the glass could indicate a problem.
Solution:
adjust the combustion air setting to the proper set-
ting. If this doesn’t seem to help, make sure the clean out
cover plates are installed in the furnace. It also could be an
indication that the furnace is getting plugged and needs a
good cleaning. Refer to the section in the manual that
covers the daily, periodic and yearly maintenance of
the furnace.
CAUTION
During troubleshooting some components are hot. Allow unit adequate time to cool. Use gloves as needed.
