Diagnostics From The Board
Heaters Voltage Reading
Check from the J7 WHITE
wire and the J2 BLUE wire
connecters on the board
to the Orange wires either
at the J8 or the J5
connecters. You should
read 0 VAC.
You should see
approximately 240 VAC
from any of these wires to
the L2 fuse with the unit
in the running position.
If you show 240 VAC at
these test points, the relay
is open. Replace the
board.
