Measure input voltage and com-
pare to rating plate.
Check input power to determine
if it is three phase or single phase
Open steamer door. Disconnect
then connect electrical power
(circuit breaker or plug)
Input voltage is within 10% of
rated voltage
Steamer wiring matches
incoming power
Reset light illuminates
Wrong model (voltage) installed
Wrong model ordered. Change
wiring at terminal block to
match incoming power.

Measure 480vac in and
208+/- 10%vac out
Measure 208 or 240vac in
and 12vac +/- 20% out
Substitute to test
Check wiring diagram
Measure from j7-pin 12 to
ground. If 12vdc +/- 20%,
control board is good
Continuity, normally closed
Check per wiring diagram
Hi-temp light will illuminate if
open
Continuity, from terminals
4 to 3, normally closed
Measure across light.
If 12vdc, light is bad
Check per wiring diagram
