Touch Control Unit And Thermocouples - AGA RANGEMASTER eR7 Field Service Manual

Touch control unit and thermocouples:

The TCU is attached to the main chassis by 4 screws, remove the screws to either exchange or gain
access to the rear of the panel, REMEMBER to support the TCU when doing this.
The thermocouples and the communications cable are all connected to the rear of the TCU.
The thermocouples are connected to the TCU in a certain order, it is important when either
replacing the TCU or a thermocouple, that the thermocouples are replaced in their correct position.
The abbreviations of the cooking zones are imprinted on the back of the TCU
BO (Baking oven),HS (Hot Spot / Boiling plate), SS (Simmer spot), SO (Simmer oven), RO (Roast oven).
The thermocouples are routed into their zones via conduits that run through the cooker and they
are held in place in a bracket in their respective zone. When a thermocouple is replaced the rubber
bungs must be put back in position to seal the conduit (see picture below).
