CHECK LIST / CAUSES
Does the green power switch light?
No: - Check power receptacle or outlet for power.
- Check line or power cord connections.
- Check door that it is completely closed.
Door switch may be interrupting power.
Yes: - Check the control knob and verify that it is
turned to desired temperature.
- Check the fuse on the controller PCB.
- Check heating element plates for continuity.
- If muffle is hot but the meter reads a low
temperature check the thermocouple for
shorts to the cabinet.
The control will slowly approach the setpoint
temperature. Set to a higher temp and then turn
down to reduce the heatup time.
On the low voltage model (100-125VAC) the
heating element plates are wired in parallel. If one
plate fails the furnace will heat very slowly and not
reach the setpoint temperature.
Slight changes in the knob rotation will have a
significant impact on the setpoint temperature. If
major differences exist between the meter and the
knob scale a temperature adjustment can be make
as described on page 9 "Temperature Adjust-
ment".
The amount of force or drag on the door move-
ment can be changed by adjusting the hex screws
located on the upper rear corners of the furnace
cabinet. Turning the screw clockwise adds drag
and requires more force.
