  • Page 6 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.
