Oven Thermocouple Kit, 11/01

PS555 Gas - thermocouples with screw ter- minal connections (no terminal blocks)

Thermocouples on these ovens are located on the rear wall. They are secured in place by two screws that are inserted through the holes in the thermocouple flange. These ovens are equipped with a three-lead, flanged thermocouple iden- tical to the one in this Kit.

NOTE FOR HIGH LIMIT THERMOCOUPLES:

These ovens have a high limit thermocouple installed in the last mounting hole at the exit end of the oven.

The thermocouple supplied in this Kit can be used to replace ANY of the temperature-sensing or high limit ther- mocouples on the oven.

1.Remove the rear shrouds and blower motor covers. This allows access to the thermocouples (on the rear wall) and screw terminals (inside the blower motor compart- ments).

2.Remove the screws that hold the thermocouple to the wall. Slide the thermocouple out of its mounting hole.

3.Disconnect the thermocouple leads. Refer to Figure 9.

•High limit thermocouples are wired directly to the high limit control module. The thermocouple’s ground wire is connected to the mounting screw for the high limit control module.

•The red and white leads from ALL temperature-sens- ing thermocouples are joined at capped screw ter- minals, located inside the left blower motor com- partment. Leads from these screw terminals con- nect to the temperature controller at the front of the oven.

The ground leads for temperature-sensing thermo- couples are connected to the chassis ground lug inside the left blower motor compartment.

4.Remove and discard the thermocouple.

5.Install the new thermocouple into the original mounting hole. Fasten it in place with the supplied #6 x 3/8” screws.

6.Wire the thermocouple as shown in Figure 9.

6.Use the kit-supplied nylon clamp and #10-16 x 3/4” screw to secure the thermocouple leads so that they will clear the shrouds, blower belts, and pulleys.

7.Close the machinery compartment door. Replace all shrouds onto the oven.
