If you apply power to the Thermolator and the control panel does
not light, you have a problem with the main power circuit or the
unit’s microprocessor board.
WARNING: Electrical Shock Hazard
Disconnect and lockout the main power supply
before proceeding.
Symptom
Applying power
does not turn on
the Thermolator or
light the control
panel.
The control panel is
lit, but the
Thermolator will
not operate when
RUN is pressed.
Possible cause
Is power reaching the
Thermolator?
Has the unit blown a
fuse?
Is the correct voltage
reaching the
Thermolator?
Is the unit in Test Mode?
Solution
❒
Verify that the main power
supply and any customer-
installed electrical discon-
nect or emergency stop
devices are in the ON posi-
tion.
❒
Verify correct electrical con-
nections between the unit
and the control, and
between the unit and the
power supply. Replace any
damaged wires or cables.
Check Fuse 1 on the mother-
board and any fuses or breakers
associated with customer-
installed disconnect devices.
Replace or reset as required.
Identify the cause of the ground
fault and correct it.
See Check-
ing and Replacing Fuses.
Check the electrical require-
ments on the unit nameplate.
Verify correct main supply
voltage to the unit and the sec-
ondary voltage supply from the
transformer to unit compo-
nents. Replace the transformer,
if necessary.
If the Test Mode LED is lit,
you must disable Test Mode on
the motherboard before resum-
ing operation.
