5.Check that the new controller is mounted into its sleeve. Then, slide the assembly into the opening in the panel from the outside. Check that the controller is upright, with the display on top and the keypad on the bottom.

6.Locate the rectangular holes on the top and bottom of the new controller’s sleeve. Attach the two kit- supplied mounting brackets against the inside panel of the oven, and into the holes in the sleeve, as shown in Figure 3. Check that the heads of the screws point to the rear of the controller.

7.Tighten the two screws evenly until the lip of the sleeve is seated tightly against the panel.

8.If there is a protective clear plastic strip on top of the display, remove it at this time.

1. Wire the new controller as follows:

•If you are replacing an Analog Temperature Controller, P/Ns 28071-0012 or 28071-0018 (see Fig. 1A), refer to Figure 4A for a listing of the new terminal numbers.

•If you are replacing an Analog Temperature Controller P/N 34983 (Fig. 1B - PS200VL models only), refer to Figure 4B for a listing of the new terminal numbers.

•If you are replacing any Digital Temperature Controller, simply reconnect ALL of the original wires and jumpers to the same terminals, as all terminals are numbered the same.

EXCEPTION: Controller P/N 32571(Fig. 1E - used on early PS360EWB ovens only) uses Termi- nals 4 & 5 for the mA output to the amplifier board. The current controller uses Terminals 15 & 16 for these connections, as shown in Figure 5A.
