OVEN THERMOSTAT (Not Used on Models with ERC)

The oven thermostat maintains the correct oven tempera- tures in the bake, broil, and self-clean operations. The thermostat is located under the control panel.

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.
