TESTING & TROUBLESHOOTING

Inputs

There are two input tabs to

accept 24VAC from the relay

board transformer (TR1).

There are two sense lines. This circuit is internal, and

signals the control to turn on the “HEAT” message in

the lower right corner of the display. One circuit is

for gas ovens, the second is for electric ovens. Both

will use the same common terminal.

There are two 2 wire connections, one

for each door switch connection

There are two tabs each for the sense of the

1000 ohm RTD probes. One cavity probe

that must always be present, and one for an

optional core probe for use with cooking.
