Filter Board
The filter board is part of the generator. Once a
selection is made by the end user, the interface
communicates with the filter board. The filter board
in turn sends power to the power board. This
energizes the inductor which induces energy into
the cooking vessel generating heat and the vessel
heats rapidly.
The filter board receives 240 VAC between L1 (X50)
and L2 (X52) and is protected by a 20 amp fuse
between E23 – E22. Verify 120 VAC between L1
(X50) and Ground (PE), 120 VAC between L2 (X52)
and Ground (PE), and 240 VAC between L1 (X50)
and L2 (X52) to the filter board, and that the fuse is
not open.
The filter board connects to the power board via
a cable X58 (filter board) to X10 (power board).
Ensure the cable connections are proper and wires
are not open. Input from the sensor is received
at X600 and should measure continuity at room
temperature. Input from the interface is received at
X67/X68 and connections as well as wiring should
be verified. If power is present, the fuse is not
open, connections and wiring are proper, the pot is
proper and no heat is generated, replace the filter
board.
