5. Check to be sure the oven’s thermocouple is the latest version flange mount style verses the obsolete version.
See Figure 4 below.
The obsolete thermocouple is not compatible with the latest temperature controller, p/n 36056, and must be
replaced with the latest thermocouple, kit p/n 33984 (300 Series ovens), and kit p/n 33985 (200 Series ovens).
The obsolete thermocouples leads are grounded to the protective sheathing which causes an error signal with
the latest controller’s thermocouple circuit.
6. After becoming familiar with the various electrical connections pertaining to the specific model oven and its
temperature controller, refer to table 2 for specific wiring instructions for all wires and any jumpers to be
reinstalled.
