Thermostat Contact Chart

In manual and timed bake operations, thermostat contacts

C-BA and 1-2 close completing the bake circuit through the

clock in a timed bake operation, the selector switch, bake

ignitor, and bake gas valve to neutral. Thermostat con-

tacts 1-2 are the cycling contacts that maintain the correct

oven temperatures.

In a broil operation, thermostat contacts C-BR and 1-2

close completing the broil circuit through the broil ignitor,

and broil gas valve to neutral. Thermostat contacts 1-2 are

the cycling contacts that maintain correct broiling tempera-

tures.

In the self-clean function with oven temperatures below

approximately 700°F., thermostat contacts COM-NO, 7-9

and 1-2 close completing the clean circuit through the latch

switch, the broil ignitor, and broil gas valve to neutral.

After the oven temperature reaches approximately 700°F.,

thermostat contacts COM-NO open and COM-NC close

now completing the circuit through the latch switch, selec-

tor switch, timer contacts, bake ignitor, and bake gas valve

to neutral. Contacts 1-2 cycle to maintain correct self-

cleaning temperatures.

The thermostat contacts can be checked for continuity by

a continuity tester or an ohmmeter set to the low ohms

range and following the thermostat contact chart. Power to

the oven must be turned off and the thermostat contact

chart. Power to the oven msut be turned off and the

thermostat wiring removed when checking the contacts for

continuity. Access to the thermostat contacts can be made

by removing the control panel.
