CONTROLLER SETTINGS
AND DIAGNOSTICS

MF3800 Test Mode

The controller "TEST MODE" is configured to run all of the
outputs (combustion fan, convection fan, igniter, air pump,
and auger motor) simultaneously at full power. During the test
mode, the auger will stop if the hopper door is opened, and
the "VACUUM FAULT CHECK SEALS" message will be displayed
if door or ash pan is open. The test mode is designed to test
that all of the outputs are working and the wiring harness
connections are correct. It is also designed to verify that the
vacuum switch and the hopper switch are functioning properly.
To activate the test mode, unplug the stove, wait 5 seconds,
and plug the stove back in. The display will first read "Ardisam
v1.00".

After three seconds, the screen will read "MF 3700 / 3800"
above, and "Ver 1-0-**" below (** denotes the version of the
software). When the screen reads "MF3700 / 3800 VER 1-0-**,
(one above the other) hold down the SCROLL key.

After three seconds, the screen will then read "<--| MF3700,
MF3800 (IGN)" (One above the other). Pressing the ENTER
key will activate the program that ignores all of the electric
ignite screens and sequences as the ENTER key activates the
controller to operate a model MF3700 (no igniter).

Pressing SCROLL will activate the MF3800 Test Mode. At this
point, the screen will read "MF3800 TEST MODE".

TEST MODE
In either case, all of the outputs on the controller will be on
full power at 110 to 120 Volts AC. Now all of the motors can
be checked for rotation and function, and the igniter and air
pump can be checked for heat production and air output.
If the auger does not run during the test mode, make sure
that the hopper switch is depressed. If the hopper switch is
depressed but the auger motor still does not turn, disconnect
the hopper switch and plug the wiring harness ends into each
other. If plugging the wiring harness ends into each other
turn the auger on, the hopper switch is defective. Replace the
switch. DO NOT LEAVE THE HARNESS BYPASSED.
USE EXTREME CAUTION WHEN METERING THE OUTPUTS
ON THE CONTROLLER. THE VOLTAGE IS 120V, AND, IF ONE
LEG OF THE METER TOUCHES TWO OUTPUT TABS AT THE
SAME TIME, THE BOARD WILL NEED TO BE REPLACED.
Always meter the OUTPUTS (1/4" tab terminals) in pairs as labeled
on the controller. Power wires are on the left, common wires are
on the right. The rest of the outputs (everything except the auger
motor) do not need input terminal bypassed to supply 120V AC to
the output DURING THE TEST MODE. SEE FIGURE 19.
If the auger motor still
doesn't turn, check the
voltage of the auger
motor leads and the
voltage of the auger
motor terminals on the
controller. Both should
read 110V to 120V AC.
If there is voltage to
the auger motor but it
doesn't turn, the auger
is either plugged, or
the motor is defective.
If there is no voltage
to the harness, put a
jumper wire between INPUT pins 1 and 2 on the input connector and
meter between OUTPUT tabs 3 and 4 on the control board. If there
is no voltage present, replace the control board (Interface Module
– Part Number 730054). This same procedure can be used for the
combustion blower, convection blower, air pump, and heat torch.
NOTE: When you have completed your work in the TEST MODE,
the only way to exit the TEST MODE sequence is to unplug the
stove. You will then need to go through the start-up process again,
reigniting the stove and selecting the appropriate fuel range.
